  • [Title] Low-grade adnexal carcinoma of the skin with multidirectional (glandular, trichoblastomatous, spiradenocylindromatous) differentiation.
  • The conjoint occurrence of follicular, sebaceous, or apocrine differentiations in a cutaneous adnexal neoplasm is a known event, more often encountered in benign neoplasms, whereas reports of cutaneous malignant adnexal tumors with bilineage or trilineage differentiation are few.
  • A new case of a cutaneous malignant adnexal neoplasm with multidirectional differentiation is reported here.
  • A 57-year-old woman presented with a long-standing, slowly growing, asymptomatic solitary tumor the size of a large nut in the coccygeal area, which was surgically excised.
  • Microscopically, the neoplasm was located in the dermis with focal extension into the subcutis.
  • We classified this tumor as a well-differentiated adnexal carcinoma demonstrating combined follicular and apocrine differentiation.
  • It differs from previously published cases of malignant adnexal tumors with multidirectional differentiation and further exemplifies the spectrum of diversity encountered in malignant proliferations with differentiation toward the folliculosebaceous-apocrine unit.

COS Scholar Universe. author profiles.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Pilomatricoma, also known as 'calcifying epithelioma of Malherbe', is a common skin adnexal tumor that mimics hair growth.
  • Its proliferating cells seem distinctly programmed to undergo terminal differentiation and death.
  • Trisomy 18 was present in a small subset of cells, suggesting a role in pilomatricoma progression, rather than in tumor initiation.
  • We conclude that trisomy 18 is a consistent feature in pilomatricoma, suggesting that genes carried on this chromosome, such as that for the antiapoptotic oncoprotein BCL2, may have a role in the growth and differentiation of this benign self-limited tumor.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Lipomatous mixed tumor of the skin.
  • An unusual tumor of the neck in a 56-year-old female is reported.
  • The tumor was composed of tubules and small cords of epithelial cells dispersed in the fibromyxoid and adipose stroma.
  • At the periphery, the tumor was not encapsulated and its border was intermingled with the subcutaneous fat.
  • Lack of decapitation secretion and the absence of long tubules suggested an eccrine origin; however, in some of the tumor areas, the cells showed brightly eosinophilic copious cytoplasm that may indicate an apocrine differentiation.
  • As an area of chondroid metaplasia was identified, the diagnosis of a mixed tumor was rendered.
  • This unusual type of skin adnexal neoplasm with unique relation of the epithelial component to the surrounding adipose tissue requires differentiation with the primary cutaneous and metastatic carcinomas.

  • [Title] The diagnostic utility of immunohistochemistry in distinguishing primary skin adnexal carcinomas from metastatic adenocarcinoma to skin: an immunohistochemical reappraisal using cytokeratin 15, nestin, p63, D2-40, and calretinin.
  • Often the distinction of primary adnexal carcinoma from metastatic adenocarcinoma to skin from breast, lung, and other sites can be a diagnostic dilemma.
  • Current markers purportedly of utility as diagnostic adjuncts include p63 and D2-40; however, their expression has been demonstrated in 11-22% and 5% of metastatic cutaneous metastases, respectively.
  • We performed CK15 and nestin, as well as previously reported stains (such as p63, D2-40, and calretinin) on 113 cases (59 primary adnexal carcinomas and 54 cutaneous metastases).
  • Expressions of p63, CK15, nestin, D2-40, and calretinin were observed in 91, 40, 37, 44, and 14% of primary adnexal carcinoma, respectively, and in 8, 2, 8, 4, and 10% of cutaneous metastases, respectively. p63 appeared to be the most sensitive marker (with a sensitivity of 91%) in detecting primary adnexal carcinomas.
  • Using chi(2) analysis, statistically significant P-values (<0.05) were observed for p63, CK15, nestin, and D2-40 in the distinction of primary adnexal carcinoma versus cutaneous metastases.
  • In logistic regression and stepwise selection for predicting a primary adnexal carcinoma, statistical significance was observed for p63, CK15, and D2-40 (P-values: <0.001, 0.0275, and 0.0298, respectively) but not for nestin (P-value=0.4573).
  • Positive staining with all three markers argues in favor of a primary cutaneous adnexal neoplasm.

11. Kumar B: Chondroid syringoma diagnosed by fine needle aspiration cytology. Diagn Cytopathol; 2010 Jan;38(1):38-40
MedlinePlus Health Information. consumer health - Salivary Gland Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Chondroid syringoma is a rare benign skin adnexal tumor of eccrine/apocrine origin affecting commonly the head and neck region.
  • It used to be previously called as mixed tumor of skin because of the presence of both the epithelial and mesenchymal components.
  • There are only few case reports describing the fine needle aspiration cytologic features of chondroid syringoma for diagnosis.
  • Overlying skin was normal, and the swelling was fixed to the skin but freely mobile over underlying structure.
  • A clinical diagnosis of dermoid cyst was entertained, and the case was subjected to FNAC.
  • On the basis of these cytologic features, a diagnosis of chondroid syringoma was made.
  • We concluded that Chondroid syringoma may be considered as a rare differential diagnosis in the swelling of head and neck region and the diagnosis can be easily confirmed or ruled out by means of fine needle aspiration cytology.

  • [Title] Adnexal skin tumors in Zaria, Nigeria.
  • BACKGROUND: Adnexal skin tumors share many features in common and differentiate along one line.
  • They may be clinically confused with other cutaneous tumors.
  • The aim of this report is to review and classify all adnexal tumors seen in a pathology department over a 16-year period.
  • METHOD: A 16-year retrospective analysis of all adnexal skin tumors seen in a large University Teaching Hospital in Nigeria from January 1991- December 2006.
  • RESULTS: Fifty-two adnexal tumors were seen, accounting for 0.9% of all cutaneous tumors seen within the same period.
  • Only two cases had a clinical diagnosis of adnexal tumor.
  • CONCLUSION: Adnexal skin tumors have distinct histological patterns which differentiates them from other cutaneous tumors.
  • Malignant adnexal tumors are uncommon in our setting.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Microcystic adnexal carcinoma: an immunohistochemical reappraisal.
  • Even though immunohistochemical comparisons of microcystic adnexal carcinoma vs infiltrative basal cell carcinoma and desmoplastic trichoepithelioma exist, they are mostly restricted to the use of a single stain.
  • In this study, we compare the expression of cytokeratin (CK) 15, CK7, CK20, CK903, carcinoembryonic antigen (CEA), CD10, CD15 and BerEP4 in 13 microcystic adnexal carcinoma, eight desmoplastic trichoepithelioma, 10 infiltrative basal cell carcinoma, and eight squamous cell carcinoma of which five exhibited ductal differentiation.
  • We found that the majority of microcystic adnexal carcinoma (92%) and desmoplastic trichoepithelioma (100%) cases expressed CK15 while the infiltrative basal cell carcinoma and squamous cell carcinoma cases were all negative.
  • Forty percent of infiltrative basal cell carcinoma expressed CK7; while only two microcystic adnexal carcinoma cases (15%) and one squamous cell carcinoma with ductal differentiation (12%) expressed CK7 in the remaining three tumor categories.
  • While the neoplastic cells were negative, luminal staining of ductal structures was noted for CK7, CD15 and CEA in some of the microcystic adnexal carcinoma, desmoplastic trichoepithelioma and squamous cell carcinoma with ductal differentiation cases.
  • Sixty percent of infiltrative basal cell carcinoma, 31% of microcystic adnexal carcinoma, and 25% of squamous cell carcinoma express CD10.
  • BerEP4 expression was noted in 38% of microcystic adnexal carcinoma, 57% of desmoplastic trichoepithelioma, 100% of infiltrative basal cell carcinoma, and 38% of squamous cell carcinoma.
  • In conclusion, we found CK15 to be a useful marker in distinguishing microcystic adnexal carcinoma from infiltrative basal cell carcinoma and squamous cell carcinoma with ductal differentiation.
  • Our experience indicates that microcystic adnexal carcinoma and desmoplastic trichoepithelioma have a similar immunohistochemical profile that is, CK15+ and BerEP4+/-; thus, additional studies are needed to separate these two entities.

  • OBJECTIVE: Metastatic cutaneous neoplasms may be difficult to differentiate from primary cutaneous neoplasms.
  • Herein, we report an unusual case of metastatic cutaneous carcinoid tumor mimicking an adnexal poroid neoplasm.
  • METHODS: A 53-year-old male man presented with a neoplasm on the vertex of the scalp, clinically resembling a pigmented basal cell carcinoma.
  • After acquiring additional clinical information and the complete excision of the neoplasm, further immunohistochemical stains supported the diagnosis a metastatic carcinoid tumor.
  • CONCLUSION: To our knowledge, this is the first case of metastatic carcinoid tumor reported that has mimicked a poroid neoplasm.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Microcystic adnexal carcinoma: an often misdiagnosed, locally aggressive growing skin tumor.
  • Microcystic adnexal carcinoma (MAC) belongs to the spectrum of locally aggressive adnexal carcinomas and most commonly occurs in the head and neck region.
  • Recently it has been proposed that MAC is an apocrine tumor.
  • In 1982, Goldstein and colleagues first reported MAC to be a distinct histologic entity characterized by a combination of keratinous cysts in the upper dermis, islands and strands of small basaloid, benign-appearing keratinocytes or squamous cells in the deeper dermis within a dense desmoplastic stroma, and areas of ductular differentiation.
  • The authors report the case of a 78-year-old woman in whom a diagnosis of MAC was made when a tumor on the right cheek recurred for the second time.
  • Local recurrences of the tumor occurred, despite histographic surgery because in hematoxylin and eosin stains, small islands of the deceptively benign-appearing small basaloid cells of MAC were not recognized as tumor cells.
  • The reported case demonstrates the difficulties in diagnosing MAC and indicates that MAC should always be considered in the differential diagnosis of slowly growing tumors in the head and neck region.

  • Primary mucinous carcinoma of the skin (MCS) is a rare skin appendage tumor and only a few cases of MCS with endocrine differentiation have been reported.
  • Here we report an additional case of primary pure MCS with endocrine differentiation arising in the face.
  • Histopathologically, the tumor was located in the dermis and subcutis, and nests of slight atypical epithelial cells were floating in the mucinous pools.
  • This tumor did not accompany carcinoma in situ or invasive non-mucinous carcinoma and was difficult to differentiate from metastatic mucinous carcinoma of the skin.
  • There was no tumor in the other organs and synaptophysin and chromogranin A were sporadically shown immunohistochemically in the tumor cells; a diagnosis of primary pure MCS with endocrine differentiation was made.
  • Although endocrine differentiation is not uncommon in pure mucinous carcinoma of the breast, there have been only a few reports published on endocrine differentiation in MCS.

  • [Title] Estimation of yttrium-90 Zevalin tumor-absorbed dose in ocular adnexal lymphoma using quantitative indium-111 Zevalin radionuclide imaging.
  • OBJECTIVE: The purpose of this investigation was to estimate radiation-absorbed dose in orbital tumors from yttrium-90 ibritumomab tiuxetan (Zevalin) radioimmunotherapy of ocular adnexal lymphoma.
  • METHODS: Three patients participating in a prospective research protocol involving treatment of ocular adnexal lymphoma with yttrium-90 Zevalin consented to quantitative radionuclide imaging to estimate tumor radiation-absorbed doses.
  • Each patient received 185 MBq of indium-111 Zevalin, followed by serial planar whole-body scanning, to derive an activity versus time curve for the tumor.
  • Single photon emission computed tomography (SPECT) and computed tomography (CT) imaging, including a calibration source, were performed at 24 h on a SPECT/CT scanner, to obtain a SPECT estimate of the radioactivity (in megabequerels) in the tumor and correct the planar curve, as well as estimate the tumor mass (M) from CT.
  • RESULTS: A right orbital tumor in one patient was visualized in both the planar and SPECT/CT images, with an estimated absorbed dose of 3.57 Gy.
  • Tumor uptake in the other two patients was not visualized.
  • CONCLUSION: The radiation dose to the orbit and ocular structures during radioimmunotherapy of ocular adnexal lymphoma is well below the threshold for significant radiation-induced ocular toxicity and about 10 times lower than that delivered during external beam radiotherapy.

  • [Title] Podoplanin is a highly sensitive and specific marker to distinguish primary skin adnexal carcinomas from adenocarcinomas metastatic to skin.
  • Distinction of primary skin adnexal carcinomas from cutaneous metastasis of adenocarcinomas is challenging.
  • In this study, we evaluated podoplanin immunoreactivity in a series of primary skin adnexal tumors and adenocarcinomas metastatic to skin using a D2-40 antibody.
  • The initial test series were composed of a total of 93 cases including 32 primary skin adnexal carcinomas, 46 benign primary adnexal tumors, and 15 cutaneous metastatic adenocarcinomas.
  • We found that variable D2-40 reactivity was seen in all of the primary cutaneous carcinomas including sebaceous carcinomas (10/10), squamous cell carcinomas (10/10), porocarcinomas (4/4), trichilemmal carcinomas (4/4), skin adnexal carcinomas not otherwise specified (4/4), and in the majority of benign skin adnexal tumors.
  • In contrast, no podoplanin immunoreactivity was seen in any of the 15 (0/15) cutaneous metastases.
  • To confirm the initial findings and to further explore the utility of podoplanin reactivity in the distinction of these tumors, we also examined a test set of 35 unknown cases, including 21 adenocarcinomas metastatic to skin and 14 primary adnexal tumors, in a blinded fashion.
  • Of the 13 D2-40 positive cases, 12 were proven to be primary adnexal tumors.
  • Our results suggest that podoplanin can be a useful tool to distinguish primary skin adnexal carcinomas form adenocarcinomas metastatic to skin with high sensitivity (94.5%) and specificity (97.2%).

  • The expression of p63 was evaluated in epidermal cells, skin appendages and metastatic tumor cells. p63 was consistently expressed in the basal and suprabasal cells of epidermis and cutaneous appendages, including the basal/myoepithelial cells of sweat glands.
  • Out of 20 benign adnexal tumors, 13 (65%) showed strong (score 3) p63 expression; the remaining seven (35%) cases had score 2.
  • All primary cutaneous carcinomas, including adenocarcinomas, expressed p63.
  • In contrast, none of the metastatic adenocarcinomas to the skin was positive for p63 (P<0.001).
  • Based on our findings, analysis of p63 expression may help in the differential diagnosis of primary vs metastatic cutaneous adenocarcinomas.

  • Bowen's disease rarely exhibits multiple combinations of premalignant and/or malignant skin lesions.
  • Bowen's disease with invasive adnexal carcinoma was originally described by Kao, but is not well recognized by clinicians due to its rarity and lack of specific clinical features of this condition.
  • Herein, we describe three unusual cases of Bowen's disease with invasive adnexal carcinoma.
  • In cases 1 and 3, we confirmed the adnexal tumor within tumors of Bowen's disease, the diagnosis of which is eccrine porocarcinoma.
  • The tumor in case 2 was characteristic to trichilemmal carcinoma.
  • Immunohistochemically, the tumor cells of Bowen's disease and the adnexal carcinoma differed in antigenicities.

  • METHODS: We evaluated expression of follicular stem-cell markers, cytokeratin (CK) 15 and nestin, in 78 benign and 23 malignant adnexal neoplasms.
  • RESULTS: CK15 and nestin expression were noted in 39 of 78 (50%) and 36 of 78 (46%) cases in the benign group, respectively (8 cutaneous mixed tumor, 10 hidradenoma papilliferum, 9 apocrine cystadenoma, 11 cylindroma and/or spiradenoma, and 9 poroma/dermal duct tumor).
  • CK15 and nestin expression were noted in 11 of 23 (48%) and 7 of 23 (30%) cases in the malignant group, respectively (6 microcystic adnexal carcinoma, 7 porocarcinoma, and 9 eccrine carcinoma).
  • Except 1, both markers were negative in 4 syringocystadenoma papilliferum, 10 hidradenoma, 1 syringofibroadenoma, 10 syringoma, 1 eccrine adenoma, 8 poroma/dermal duct tumor, 5 eccrine hidrocystoma, and 1 apocrine carcinoma.
  • CONCLUSIONS: Given that follicular germinative cells give rise to the folliculosebaceous apocrine unit, expression of CK15 and nestin in the majority of cutaneous mixed tumor, hidradenoma papilliferum, apocrine cystadenoma, and cylindroma/spiradenoma is suggestive of an apocrine origin/differentiation of these neoplasms.

  • [Title] Monoclonal antibody Ber-EP4 reliably discriminates between microcystic adnexal carcinoma and basal cell carcinoma.
  • BACKGROUND: Sclerosing cutaneous neoplasms often represent a diagnostic challenge.
  • It is diagnostically highly reliable in the differentiation between basal cell carcinoma and cutaneous squamous cell carcinoma.
  • In this study, we report its application in the differential diagnosis of microcystic adnexal carcinoma, desmoplastic trichoepithelioma and basal cell carcinoma.
  • METHODS: Biopsy samples from 28 sclerosing and infiltrating basal cell carcinomas, 13 microcystic adnexal carcinomas and 16 desmoplastic trichoepitheliomas were examined after immunohistochemical staining with Ber-EP4.
  • RESULTS: Ber-EP4 did not label any of the microcystic adnexal carcinomas, whereas all 28 basal cell carcinomas were Ber-EP4 positive.
  • CONCLUSIONS: Ber-EP4 reliably differentiates microcystic adnexal carcinoma from basal cell carcinoma to the same extent as it distinguishes the latter tumor from squamous cell carcinoma.
  • While it stains the majority of desmoplastic trichoepitheliomas, these tumors still have to be considered in the differential diagnosis with microcystic adnexal carcinoma, when Ber-EP4 is applied.

  • BACKGROUND: Granular cell tumor (GCT), also known as Abrikossoff tumor, is an uncommon benign neoplasm, probably of neural origin derived from Schwann cells.
  • OBJECTIVES: We aimed to analyze the clinical, histologic, and immunohistochemical characteristics associated with this tumor and to determine whether these findings correspond to those reported to date in the literature.
  • METHODS: In this retrospective study of 34 patients with histologic diagnosis of GCT, we analyzed clinical characteristics (site, age, sex, duration, and suspected diagnosis), histological findings (border, cell atypia and mitoses, involvement of adnexal structures, pseudoepitheliomatous hyperplasia, and presence of the recently described pustulo-ovoid bodies), and immunohistochemical findings (S-100 staining in 16 randomly selected cases).
  • The most frequently suspected clinical diagnosis was fibroma (17.65 %).
  • CONCLUSIONS: Our series confirms the characteristics described previously for GCT, except for certain peculiarities, and supports the presence of pustulo-ovoid bodies as an additional histologic finding for diagnosis of this tumor.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Adnexal clear cell carcinoma with comedonecrosis: clinicopathologic analysis of 12 cases.
  • CONTEXT: Cutaneous clear cell tumors can pose a diagnostic challenge even to the experienced dermatopathologist; this is partly because of limitations of existing diagnostic categories.
  • OBJECTIVE: To describe a previously unrecognized, distinctive cutaneous adnexal carcinoma capable of an aggressive clinical course.
  • Histologically, adnexal clear cell carcinoma with comedonecrosis was characterized by dermal proliferation of nests of epithelial cells showing distinctive zonal arrangement.
  • The periphery of the tumor nests was formed by squamoid cells merging with centrally located clear cell areas containing foci of comedonecrosis.
  • No ductal, cuticular, or apocrine differentiation was seen.
  • CONCLUSIONS: Adnexal clear cell carcinoma with comedonecrosis appears to be a distinctive adnexal neoplasm that has to be distinguished from more indolent squamous cell and tricholemmal carcinomas.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Expression of Bcl-x in normal skin and benign cutaneous adnexal tumors.
  • Little is known about the expression of Bcl-x in cutaneous adnexal structures and benign cutaneous adnexal tumors.
  • METHODS: Tissues from 31 cases of benign cutaneous adnexal tumors (five trichofolliculomas, five trichoepitheliomas, two sebaceous adenomas, five apocrine hidradenomas, five eccrine poromas, five eccrine spiradenomas, and four syringomas) were immunostained for Bcl-x.
  • RESULTS: Strong staining for Bcl-x was seen in cells of the epidermal granular layer and inner root sheath of hair follicles.
  • CONCLUSIONS: The degree of Bcl-x expression in cutaneous adnexal glandular structures appears to be related to their mode of secretion, being strongest in cells with apoptotic degradation of the entire cell (sebocytes).
  • This pattern is recapitulated in the corresponding benign cutaneous adnexal tumors.
  • Bcl-x may be useful in identifying cells with sebaceous differentiation in poorly differentiated adnexal tumors.

  • [Title] Cutaneous adnexal tumor with an unusual presentation--discussion of a potential diagnostic pitfall.
  • The clinical presentation of skin adnexal tumors is nonspecific, and histologically; the differential diagnosis between primary cutaneous adnexal malignant carcinomas and metastatic tumors with a visceral origin can be challenging.
  • The biopsy showed an intradermal proliferation of malignant epithelioid cells with ductal differentiation, histologically compatible with metastatic breast carcinoma.
  • However, the tumor cells labeled strongly and diffusely not only for pancytokeratin and cytokeratin (CK7) but also with p63 and CK5/6; carcinoembryonic antigen highlighted the ductal structures.
  • Based on the p63 and CK5/6 positivity, the differential diagnosis also included the possibility of a primary adnexal neoplasm and a complete excision was advised.
  • The reexcision specimen revealed residual infiltrating dermal tumor and an overlying intraepithelial component with marked cytologic atypia and focal duct formation, diagnostic of a primary cutaneous adnexal tumor with ductal differentiation (porocarcinoma).
  • Immunohistochemical studies (like p63 and CK5/6) can help to differentiate a primary cutaneous neoplasm from a metastatic lesion.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Use of p63 expression in distinguishing primary and metastatic cutaneous adnexal neoplasms from metastatic adenocarcinoma to skin.
  • p63, a recently identified homologue of the p53 gene, is mainly expressed by basal and myoepithelial cells in skin.
  • Others and we have shown the value of p63 in distinguishing primary adnexal tumors from visceral adenocarcinomas metastatic to skin.
  • We now investigate the pattern of p63 expression in metastases from skin adnexal carcinomas and their cognate primaries and evaluate p63 expression in a larger case series of malignant cutaneous adnexal neoplasms.
  • Immunohistochemical analysis for p63 was performed on 13 metastases of adnexal carcinomas and their corresponding primary tumors.
  • Twenty visceral metastatic adenocarcinomas to the skin and 7 primary mucinous carcinomas with cutaneous or visceral origin were compared.
  • The majority (90.9%) of primary adnexal tumors strongly expressed p63 and their metastases labeled similar to their cognate primary tumors.

  • [Title] Cutaneous carcinosarcoma: adnexal vs. epidermal types define high- and low-risk tumors. Results of a meta-analysis.
  • OBJECTIVE: We report four cases of cutaneous carcinosarcoma (CS) and perform a meta-analysis of the cutaneous CS literature.
  • RESULTS: CS occurred in elderly patients (mean of 80 years) on sun-damaged skin, and were keratotic papules of short duration.
  • Literature review identified 38 cases of cutaneous CS that could be broadly classified into two distinct groups.
  • Epidermal-derived (basal or squamous cell carcinoma epithelial component) CS arose on the sun-damaged skin of the head and neck of elderly males (mean age 72 years) and had a 70% 5-year disease-free survival.
  • In contrast, adnexal CS (spiradenocarcinoma, porocarcinoma, proliferating tricholemmal cystic carcinoma, or matrical carcinoma) occurred in younger patients (mean age 58 years), showed recent growth in a long-standing nodule and had a 25% 5-year disease-free survival.
  • Age less than 65 years, recent growth, long-standing skin tumor, and tumor size greater than 2 cm significantly correlated with poor outcome.
  • CONCLUSIONS: Cutaneous CS is an aggressive skin cancer with high risk for advanced disease.

  • [Title] Mutations in exon 3 of the CTNNB1 gene (beta-catenin gene) in cutaneous adnexal tumors.
  • Previous studies suggested that mutant beta-catenin gene cells in cutaneous adnexal tumors with matrical differentiation contribute to their tumorigenesis.
  • Except for pilomatricoma and pilomatrical carcinoma, only a handful of other cutaneous adnexal tumor types have been studied.
  • DNA was extracted from 86 lesions including 17 proliferating tricholemmal and trichilemmal tumors, 15 trichoblastomas, 7 trichoadenomas, 4 pilomatricomas, 1 pilomatrical carcinoma, 4 basal cell carcinomas (BCCs) with shadow cells, 2 trichofolliculomas, 3 BCCs with sebaceous differentiation, 9 sebaceous adenomas, 6 sebaceomas, 14 sebaceous carcinomas (both ocular and extraocular forms), 2 gigantic horns, and 2 apocrine mixed tumors with shadow cells and subjected to polymerase chain reaction with newly designed primers encompassing glycogen synthase kinase-3beta phosphorylation sites of the CTNNB1 gene.
  • These included 5 different point mutations, 3 of them identified in 2 different tumors: S23N (cribriform trichoblastoma), D32Y (pilomatricoma and craniopharyngioma), G34R (pilomatrical carcinoma and craniopharyngioma), S37F (2 BCCs with shadow cell differentiation), and G34V (craniopharyngioma).

  • INTRODUCTION AND OBJECTIVES: Microcystic adnexal carcinoma is a rare and aggressive tumor that manifests clinically as a subcutaneous nodule located on the head or neck.
  • The tumor can be confused clinically and histologically with other benign and malignant skin lesions, often leading to inappropriate initial treatment.
  • The chief concern with microcystic adnexal carcinoma is the elevated morbidity and the high rate of recurrence after wide local excision.
  • MATERIAL AND METHODS: We reviewed the medical histories of 6 consecutive patients with microcystic adnexal carcinoma who underwent Mohs micrographic surgery in our dermatology department between 1995 and 2007.
  • This would provide a rationale for definitive radical treatment of the primary tumor from the outset to avoid the complications associated with recurrence.
  • The site and the absence of recurrence in all our patients who underwent Mohs micrographic surgery support the use of this technique as the treatment of choice in microcystic adnexal carcinoma.

  • [Title] Periocular microcystic adnexal carcinoma: management and outcome with Mohs' micrographic surgery.
  • PURPOSE: To report a series of patients with periocular microcystic adnexal carcinoma (MAC) treated with Mohs' micrographic surgery (MMS).
  • METHODS: This series included all patients treated with MMS for periocular MAC, who were monitored by the Skin and Cancer Foundation Australia between 1993 and 2002.
  • The tumor was initially misdiagnosed as basal cell carcinoma in 3 patients and squamous cell carcinoma in 1 patient.
  • The average number of excision levels required for complete removal of the tumor during MMS was 2.2 (range 1-6).
  • Perineural invasion was recorded in one patient.Five-year follow-up data was available for 3 patients, and there was no tumor recurrence in any of these cases.
  • CONCLUSION: The low 5-year recurrence rate of periocular MAC with MMS emphasizes the importance of margin-controlled excision of this tumor.

  • OBJECTIVE: To find the risk factors of torsion and malignancy for adnexal tumors during pregnancy.
  • PATIENT(S): Patients from 1990 to 2004 with adnexal tumors >or=4 cm during pregnancy.
  • MAIN OUTCOME MEASURE(S): Tumor size, progression, pathology, incidence of malignancy, and torsion.
  • In 174 patients who were followed through pregnancy with known tumor existence, 14.84% +/- 3.05% encountered tumor torsion.
  • Adnexal masses with sizes between 6 and 8 cm had a significantly higher risk of torsion compared with other sizes (22.41% vs. 9.48%; odds ratio 2.8, 95% confidence interval [CI], [1.1, 6.6]).
  • Tumor diameters >or=10 cm at initial diagnosis had a higher risk of malignancy versus smaller sizes (8.77% vs. 0.85%; odds ratio 11.2, 95% CI, [1.3, 97.9]), and tumor growth rates >or=3.5 cm/week also had a significantly higher risk of malignancy versus lower rates (8.33% vs. 0.88%; odds ratio 10.2, 95% CI, [1.0, 101.2]).
  • CONCLUSION(S): Adnexal tumors bearing higher risks for torsion and malignancy should be strongly considered for an aggressive strategy of management during pregnancy.

  • [Title] "Squamoid eccrine ductal carcinoma": an unusual low-grade case with follicular differentiation. Are these tumors squamoid variants of microcystic adnexal carcinoma?
  • Squamoid eccrine ductal carcinoma is a rare primary cutaneous tumor exhibiting both squamous and adnexal ductal differentiation.
  • The cell of origin of these tumors is unknown, and they have been classified both as variants of cutaneous squamous cell carcinoma and as a type of eccrine carcinoma.
  • We report an additional case of a slow-growing tumor, occurring on the great toe of a 61-year-old woman, which was unusual as it showed follicular differentiation in addition to squamoid and ductal areas.
  • The lesional cells were positive for cytokeratins 7 and 17, carcinoembryonic antigen (which highlighted the ductal structures), and p63 (favoring a primary cutaneous tumor) and showed low levels of staining with Ki-67 and p53, consistent with a low-grade tumor.
  • We postulate that these tumors may be closely related to microcystic adnexal carcinoma and similarly show differentiation along both follicular and ductal lines, likely indicating folliculosebaceous-apocrine, rather than eccrine, origin or differentiation.

  • Several important cutaneous neoplasms present with basaloid cells in the dermis.
  • Desmoplastic trichoepithelioma (DTE), infiltrative/morpheaform basal cell carcinoma (BCC), and microcystic adnexal carcinoma (MAC) are tumors in this category that may be difficult to differentiate, especially when evaluating thin biopsy specimens.
  • An accurate diagnosis has important clinical implications.
  • While DTE is a benign neoplasm with indolent behavior, infiltrative/morpheaform BCC and MAC can be highly aggressive, leading to substantial local destruction and potential metastasis.
  • We present a patient with an unusual tumor demonstrating basaloid cells in the dermis and discuss the diagnostic approach for these lesions, emphasizing the potential role of cytokeratin 20 (CK20) in determining the need for Mohs micrographic surgery.

  • [Title] Cutaneous clear cell adnexal carcinoma in a dog: special reference to cytokeratin expression.
  • A 5-year-old, male Bichon-Frise dog presented with a cutaneous mass in the basal region of the auricle.
  • Histologically, the cutaneous neoplasm was comprised of lobules with solid cellular proliferation separated by thin fibrous septa.
  • Immunohistochemical examinations showed that tumor cells were positive for pan-cytokeratin (CK) (AE1/AE3 and CAM5.2), CK8 and CK18, but negative for pan-CK (KL1), CK7, CK14, CK16 and CK20.
  • Double-labeled immunofluorescence testing indicated that neoplastic cells frequently co-expressed CK and vimentin, suggesting divergent differentiation of tumor cells.
  • Based on these findings, the tumor was diagnosed as canine clear cell adnexal carcinoma.

  • Endometrioid carcinoma is a common tumor of the female genital tract, mainly affecting the uterus corpus and ovary.
  • The female adnexal tumor of probable wolffian origin (FATWO), although occasionally seen elsewhere, is most typically encountered in the broad ligament.
  • The tumor was confined to the tube and strongly resembled FATWO.
  • Immunohistochemically, the tumor cells were positive for AE1/AE3, epithelial membrane antigen (EMA), and p16, but negative for CD10, inhibin-alpha, calretinin, vimentin, myogenin, and desmin, CD99,CgA, and Syn.
  • We review the previously published cases of endometrioid carcinomas of the fallopian tube resembling FATWO, and discuss the principal differential diagnosis of the tumor in the fallopian tube.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] SOX9 expression is a general marker of basal cell carcinoma and adnexal-related neoplasms.
  • Activation of the Shh pathway is a major cause of cutaneous basal cell carcinoma (BCC).
  • Here we test whether activation of SOX9 is a general feature of BCC, or whether it could be used as a biomarker to better define subtypes of these skin tumors.
  • In addition we investigated SOX9 expression in other skin epidermal tumors.
  • Staining was heterogeneous and could be detected among the basaloid cells of the palisading cell layer as well as in the tumour nest.
  • SOX9 expression was detected in all adnexal tumors analyzed and absent in Bowen's disease and Merkel tumor.
  • CONCLUSIONS: SOX9 expression is a general feature of BCC and adnexal skin neoplasms, suggesting a contribution of SOX9 to the pathogenesis of these tumors.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Microcystic adnexal carcinoma involving a large portion of the face: when is surgery not reasonable?
  • BACKGROUND: We report a case of microcystic adnexal carcinoma (MAC) involving a large portion of the face, one of the largest of any MAC reported thus far in this area, and review the literature regarding the nature of the tumor and available treatments.
  • We also review all of the reported cases of metastases and the possible role of radiation in the etiopathogenesis of this tumor.
  • CONCLUSION: Mohs surgery should be the treatment of choice for this tumor; however, when extirpation entails sufficiently large morbidity, given the low rate of metastases and mortality, observation is a reasonable alternative.

  • OBJECTIVES: The purpose of this study was to compare 2-dimensional and 3-dimensional color and power-Doppler as measured with blood flow indices for the prediction of malignancy in complex adnexal masses.
  • METHODS: Two hundred eighty women with complex adnexal masses (mean age, 46,3 years (range, 13-83 years) were evaluated by 2-dimensional and 3-dimensional power-Doppler imaging.
  • Complex adnexal mass was defined as the presence of at least one of the following features: solid areas, thick papillary projections, thick septa, or purely solid echogenicity.
  • Tumor volume, sonomorphology and Doppler indices (PI, RI), as well 3-dimensional power-Doppler assessment (VI, FI, VFI) were calculated.
  • All tumors were surgically removed and definitive histological diagnosis was obtained in each case.
  • However, the highest sensitivity of 3D indices for malignant tumor detection was found for FI (42.9%).
  • CONCLUSION: Three-dimensional power-Doppler imaging has diagnostic potential for the discrimination of benign and malignant complex adnexal masses, but specific, possibly most vascularised areas of each tumor have to be examined in detail to improve not yet satisfactory predictive values of this method.

  • [Title] p75 Neurotrophin receptor differentiates between morphoeic basal cell carcinoma and desmoplastic trichoepithelioma: insights into the histogenesis of adnexal tumours based on embryology and hair follicle biology.
  • BACKGROUND: Tumour development is frequently described in the basic pathology literature as a recapitulation of embryogenesis.
  • However, a link between the embryology of the skin and the histogenesis of adnexal tumours has been largely overlooked.
  • We therefore speculated that it is involved in the histogenesis of follicular adnexal tumours.
  • OBJECTIVES: To describe the expression pattern of p75NTR during cutaneous embryogenesis, in the adult hair follicle and in morphoeic basal cell carcinoma and desmoplastic trichoepithelioma.
  • In contrast, the lack of p75NTR expression in morphoeic basal cell carcinoma favours a concept of this tumour as a more primitive follicular lesion with the characteristics of a carcinoma and not a hamartoma.
  • We suggest including p75NTR as a tool in the differential diagnosis between morphoeic basal cell carcinoma and desmoplastic trichoepithelioma.

  • [Title] PAX8 discriminates ovarian metastases from adnexal tumors and other cutaneous metastases.
  • BACKGROUND: The distinction of metastatic ovarian carcinoma from other metastatic carcinomas and primary adnexal lesions in the skin is often difficult.
  • Identification of ovarian cutaneous metastases may be of benefit in patients with familial breast-ovarian carcinoma syndrome.
  • METHODS: PAX8 immunohistochemical analysis was performed on 24 cases of metastatic adenocarcinomas to the skin and compared with 7 cases of primary adnexal lesions and also compared with p63 immunohistochemical staining results.
  • Patients with metastatic adenocarcinomas had clinically documented primary malignancies, and patients with primary adnexal carcinomas had no known history of another adenocarcinoma.
  • RESULTS: Cutaneous ovarian and renal cell carcinoma metastases (2/2 and 8/8, respectively) showed positive nuclear expression of PAX8.
  • PAX8 immunohistochemical staining in primary adnexal and other cutaneous metastases was completely negative (0/7 and 0/16, respectively).
  • The p63 expression profile supported the distinction between adnexal and metastatic adenocarcinomas.
  • CONCLUSIONS: Although cutaneous ovarian metastasis is a rare phenomenon, the prognosis is extremely poor.
  • PAX8 expression is a useful marker that effectively discriminated metastatic ovarian carcinomas from metastatic breast carcinomas and primary adnexal tumors.

  • [Title] Sentinel lymph node biopsy for ocular adnexal melanoma: experience in 30 patients.
  • PURPOSE: To report the findings on sentinel lymph node biopsy (SLNB) in 30 patients with ocular adnexal (conjunctival or eyelid) melanomas.
  • PARTICIPANTS: Thirty patients with diagnosis of eyelid or conjunctival melanoma.
  • METHODS: All patients with ocular adnexal melanoma who underwent SLNB at The University of Texas MD Anderson Cancer Center between December 2000 and July 2008 are the subject of this report.
  • MAIN OUTCOME MEASURES: Findings on preoperative lymphoscintigraphy, SLNB, histopathologic examination of the primary tumor and sentinel lymph nodes (SNL), and nodal recurrence after SLNB.
  • RESULTS: Tumor sites were as follows: bulbar conjunctiva only, 14 patients; palpebral conjunctiva only, 8 patients; both bulbar and palpebral conjunctiva, 4 patients; and eyelid skin only, 4 patients.
  • CONCLUSIONS: Sentinel lymph node biopsy is effective for identifying nodal micrometastasis in patients with ocular adnexal melanoma and provides important prognostic information.
  • We recommend consideration of SLNB for patients with intermediate-thickness ocular adnexal melanoma and those with ulceration.

  • [Title] A case of canine cutaneous clear cell adnexal carcinoma with prominent expression of smooth muscle actin.
  • Cutaneous clear cell adnexal carcinoma was found in the right lip of a 14-year-old male castrated Shih Tzu.
  • Histologically, the tumor mostly consisted of neoplastic cells with clear or vacuolated cytoplasms and contained frequent tubular structures.
  • In addition, immunohistochemistry revealed that the tumor cells were positive for pan-CK (AE1/AE3, KL1, CAM 5.2), CK-7, CK-8, CK-14, CK-15, CK-18, vimentin and alpha-smooth muscle actin (SMA) with varied intensity and positivity.
  • Among these marker proteins, SMA was positive in 75% of the tumor cells.
  • On the other hand, CK-15, which is a specific marker of follicular stem cells, was expressed in less than 1% of the tumor cells.
  • Based on these findings, the tumor showed diverse differentiation in apocrine sweat glands and the inner and outer root sheaths of hair follicles, indicating the follicular stem cell to be the origin of this tumor.

  • We suggest that this may be a clue to the adnexal nature of BCC and propose that BCC is the most primitive follicular tumor.

  • We report a rapidly growing nodular swelling misdiagnosed as round cell tumor cytologically and found to be pilomatricoma histopathologically.
  • CASE: A 32-year-old man presented with a rapidly growing, mobile nodule on his left arm for 4 months with fixed, shiny overlying skin.
  • Cytologically the diagnosis of blue round cell tumor was made.
  • The diagnosis was pilomatricoma bistopathologically.
  • To avoid misdiagnosis, all skin-based nodules should undergo extensive cytologic sampling from diferent sites.
  • Pilomatricoma should be considered in diferential diagnosis when primitive-appearing cells are aspirated, especially in rapidly growing early lesions.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Tumor of the follicular infundibulum: an epidermal reaction pattern?
  • Our recent experience indicates that the desmoplastic variant of tumor of the follicular infundibulum (TFI) is not, as previously believed, entirely uncommon.
  • To clarify the defining clinical and microscopic features of TFI with special relevance to the histologic variants, we retrospectively reviewed cases with a histologic diagnosis of TFI between 1999 and 2008.
  • Other features included an eosinophilic cuticle (70%), ductal differentiation (45%), cornoid lamellae (17%), and desmoplasia (11%).
  • Of interest, approximately one fourth (25%) were associated with other cutaneous lesions, which included basal cell carcinoma, actinic keratosis, desmoplastic malignant melanoma, junctional melanocytic nevus, tricholemmoma, and epidermal inclusion cyst.
  • In addition to expanding the constellation of the clinical and histopathologic findings, the increased association with other cutaneous lesions in the current study suggests that TFI may represent an epidermal reaction pattern.

  • Histologically, a nodular dermal proliferation composed of poorly differentiated epithelioid cells in nests and focally forming ducts with pseudopapillary architecture comprised the primary tumor.
  • Metastatic tumor involved nine of 28 nodes.
  • Interphase fluorescence in situ hybridization (FISH) demonstrated chromosomal amplification of the Her-2/neu locus within the tumor and a nodal metastasis.
  • We believe this to be the first demonstration of Her-2/neu amplification in a malignant skin adnexal tumor.
  • In analogy to breast carcinoma, these findings suggest the applicability of trastuzumab for patients with metastatic adnexal carcinomas demonstrating Her-2/neu amplification.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Eccrine porocarcinoma of the head: an important differential diagnosis in the elderly patient.
  • BACKGROUND: Eccrine porocarcinoma is a rare malignant tumor of the sweat gland, characterized by a broad spectrum of clinicopathologic presentations.
  • Instead, eccrine porocarcinoma frequently occurs on the lower extremities, trunk and abdomen, but also on the head, resembling various other skin tumors, as illustrated in the patients described herein.
  • All patients were initially diagnosed as having epidermal or melanocytic skin tumors.
  • Only after histopathologic examination were they classified as eccrine porocarcinoma, showing features of epithelial tumors with abortive ductal differentiation.
  • CONCLUSION: Eccrine porocarcinomas are potentially fatal adnexal malignancies, in which extensive metastatic dissemination may occur.
  • Porocarcinomas are commonly overlooked, or misinterpreted as squamous or basal cell carcinomas as well as other common malignant and even benign skin tumors.
  • Knowledge of the clinical pattern and histologic findings, therefore, is crucial for an early therapeutic intervention, which can reduce the risk of tumor recurrence and serious complications.

  • Spindle cell lipoma (SCL), dermatofibrosarcoma protuberans (DFSP), and solitary fibrous tumors (SFT) are cutaneous CD34+ spindle cell tumors that may exhibit histopathologic and immunophenotypic overlap.
  • Ten morphologic characteristics were analyzed in a group of 5 SCLs, 6 cutaneous SFTs, and 12 DFSPs.
  • However, adnexal entrapment, defined as diffuse proliferation of tumor cells around pilosebaceous and eccrine structures with minimal disruption or expansion of the dermis, was a feature seen in 10 of the 12 DFSPs and in none of the SFTs or SCLs.
  • The number of samples included in the study is relatively small, in part due to the rarity of cutaneous solitary fibrous tumors.

  • [Title] A case of implantation dermatosis that formed a tumor.
  • A 51-year-old man visited our hospital complaining of a tumor located above his lip.
  • The lesion turned into a tumor and gradually enlarged.
  • The tumor was well circumscribed, smooth and covered with reddish, partially milk-white skin.
  • During surgery to remove the tumor, a piece of a chopstick was found in the subcutaneous tissue, and a diagnosis of implantation dermatosis (ID) was made.
  • On histology, the tumor appeared as an abscess that had increased fibroblasts, small vessels and a large number of neutrophils.
  • In the Japanese published work, we found 86 cases of ID; three were similar to our case and had been clinically diagnosed as adnexal tumors.

  • BACKGROUND: Eccrine mixed tumors of the skin are rare adnexal neoplasms, and their morphological spectrum is not well established.
  • METHODS: Among 70, 000 skin biopsies, 5 were diagnosed as eccrine mixed tumors.
  • No signs of follicular or sebaceous differentiation were seen.
  • The stroma was mucinous and chondroid, calcification ranging from little to extensive with bone formation in 3 examples giving the impression of a chondroid or osseous neoplasm.

  • The seminal article of Drs Franz Enzinger and Renyuan Zhang in 1988 defined plexiform fibrohistiocytic tumor (PFHT) as a distinctive entity.
  • Perineural growth was observed in 5 cases, peri-Pacinian corpuscle growth in 2 cases, adnexal trapping in several, and, increased hyalinized collagen in 17 cases.
  • Overall, the findings were very similar to the original observations made by Dr Enzinger and his colleague, with the minor exceptions of roughly equal sex distribution (possibly due to timely referral bias), and additional morphologic features of myxoid change, adnexal sparing, increased inflammation, and microfat similar to recently described lipofibromatosis.

  • [Title] Report of a case: primary mucinous carcinoma of the skin.
  • Primary mucinous carcinoma of the skin is an extremely rare adnexal tumor that is thought to originate from eccrine sweat glands.
  • The neoplasm usually arises on the head and neck, with the most commonly involved area being the periorbital region.
  • The tumor is typically a solitary, asymptomatic nodule, cyst, or ulcer that is slow growing with low metastatic potential.
  • Since primary mucinous carcinoma of the skin is such a rare neoplasm (fewer than 130 cases have been reported to date), a complete workup should be conducted to rule out other internal malignancies that may metastasize to the skin.
  • We report a case of primary mucinous carcinoma of the skin, and discuss the clinical presentation, histology, treatment, course, and prognosis.

  • A 1-cm-diameter, red, raised, cutaneous mass over the dorsal surface of the left third metacarpal of a 6-year-old neutered male yellow Labrador Retriever was aspirated.
  • The cytologic interpretation was malignant neoplasia with histiocytic inflammation.
  • Histologically, the tumor was diagnosed as a basal cell epithelioma.
  • Neoplasms that once were lumped into the broad histologic diagnosis of basal cell tumors have since been split into distinct entities, dependent on evidence of differentiation into epidermis, trichofollicular epithelium, or sweat or sebaceous glands.
  • Although histologic reclassification has resulted in removal of most of these entities from the original basal cell tumor category, a cytologic diagnosis of basal cell tumor continues to be used to represent the large, heterogeneous group of epidermal, trichofollicular, and adnexal skin tumors with basal cell characteristics.
  • The case in this report demonstrates the heterogeneity of neoplasms that may be diagnosed cytologically as basal cell tumors and supports the need for cytologic criteria and nomenclature that better reflect potential variation in tissue differentiation.

  • We report 18 cases of cutaneous angiosarcoma with predominant or exclusive epithelioid morphology.
  • In elderly patients scalp or facial lesions and cutaneous lesions arising within irradiated breast skin predominated.
  • Microscopically, the tumors were composed of packed polygonal cells with focal evidence of endothelial differentiation.
  • Diverging phenotypes included syncytial growth of large cells with clear nuclei and prominent nucleoli, micronodules of tumor cells scattered in dermis, predominance of discohesive plasmacytoid polygonal cells with abundant bright eosinophilic cytoplasm, sheets of clear cells with coarse granular cytoplasm, trabecular and cord arrangement of tumor cells splaying the dermal collagen, or a pseudoglandular appearance owing to clear cell tubular arrangement with open lumina.
  • These cases posed further diagnostic challenges simulating lymphoma, melanoma, lymphoepithelioma-like carcinoma, adnexal carcinoma, and neuroendocrine carcinoma.
  • Of the 9 patients available for follow-up, 5 were alive and apparently well, 2 had recurrent disease, and 2 had died of tumor.
  • Our data show that epithelioid cutaneous angiosarcoma may have a broad morphological spectrum, raising interpretive challenges on microscopy.

  • [Title] Value of p63 and podoplanin (D2-40) immunoreactivity in the distinction between primary cutaneous tumors and adenocarcinomas metastatic to the skin: a clinicopathologic and immunohistochemical study of 79 cases.
  • The distinction of metastatic carcinomas to the skin from poorly differentiated primary cutaneous carcinomas and sometimes primary benign adnexal tumors can pose a significant diagnostic challenge.
  • The purpose of this study was to evaluate the role of p63 and podoplanin (D2-40) immunoreactivity for separating primary skin tumors vs. cutaneous metastases of carcinomas from internal organs.
  • Thirty seven primary tumors and 42 cutaneous metastatic adenocarcinomas were evaluated.
  • The 37 primary cutaneous tumors included 14 cases of benign adnexal tumors, 9 malignant skin adnexal neoplasms, and 14 primary squamous and basal cell carcinomas.
  • The 42 metastatic adenocarcinomas all corresponded to metastases from patients with a well-documented history of a primary tumor at another location.
  • We found variable positivity with podoplanin in all primary cutaneous neoplasms including spiradenoma (6/6), hidradenoma (2/4), cylindroma (3/3), desmoplastic trichilemmoma (1/1), poorly differentiated squamous cell carcinoma (4/4), sebaceous carcinoma (1/1), basal cell carcinoma (4/10), trichilemmal carcinoma (2/2), eccrine carcinoma (3/3), microcystic adnexal carcinoma (1/1), adnexal carcinoma NOS (1/1), and porocarcinoma (1/1).
  • In regards to p63, all cases of primary cutaneous tumors were positive for p63 (37/37); in contrast, all cutaneous metastatic carcinomas were negative (0/42).
  • Sensitivity, specificity, and positive and negative predictive values of podoplanin and p63 immunoreactivity to separate primary skin neoplasms from metastatic carcinomas were 78.4, 100.0, 100.0 and 84.0% for podoplanin, respectively, and 100.0, 100.0, 100.0 and 100.0% for p63, respectively.
  • The differences in p63 and podoplanin immunohistochemical expression between primary skin tumors and metastatic carcinomas to the skin were statistically significant (p < 0, 0001).
  • The results of our study suggest that the combined expression of p63 and podoplanin are a useful adjunct for the diagnosis of skin tumors in the clinical setting of a questionable metastasis and may be relatively specific for distinguishing primary skin tumors from metastatic carcinomas to the skin.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Ocular adnexal pseudo-cyst formation as a characteristic feature of perineural spread in squamous cell carcinoma.
  • All cases had associated cutaneous squamous cell carcinoma involving the face or scalp, and, in 4 cases, the primary tumor could be identified in the vicinity of the affected orbit.
  • The cystic tumor deposits were assessed histologically with both hematoxylin and eosin and immunoperoxidase stains (S100 protein for neural structures identification and MNF116 as a keratin marker).
  • This demonstrated malignant squamous epithelium both within and around the wall of the tumor deposit and, in continuity, within the nerve running through the lesion.
  • Some nerves showed substantial areas of fibrosis, representing obliteration of the nerve structure caused by involvement by tumor.
  • CONCLUSIONS: The presence of a cystic lesion in association with sensory or motor deficit in the periorbital region should suggest a diagnosis of perineural spread from a cutaneous squamous cell carcinoma.
  • Because these patients may present to the ophthalmologist first, an awareness of this entity is of critical importance to avoid the delayed diagnosis seen in half of our cases.

  • [Title] CK7 expression in primary cutaneous squamous cell carcinoma.
  • AIM: To evaluate cytokeratin 7 (CK7) immunoreactivity in invasive primary cutaneous squamous cell carcinomas (SCCs).
  • METHODS: Twenty-seven primary cutaneous SCCs from 25 patients were evaluated for tumor grade using hematoxylin and eosin-stained slides and for percentage and intensity of immunoreactivity for CK7.
  • No glandular or tubular differentiation was present.
  • Of immunoreactive cases, percentage of tumor staining and distribution of immunoreactivity was documented.
  • The remaining immunoreactive tumor was moderately differentiated, with 1+ intensity and 5% staining in an area of microinvasion.
  • CONCLUSION: A subset of cutaneous SCCs, in particular, poorly differentiated tumors, may show focal-to-partial immunoreactivity for CK7.
  • This is important to bear in mind when immunohistochemistry is used to distinguish SCC from simulants, such as porocarcinoma, or other adnexal carcinomas with squamous metaplasia.
