  • [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 addition, a comparison with squamous cell carcinoma has not been reported previously.
  • 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.

  • [Title] Sex steroid hormone receptors in human skin appendage and its neoplasms.
  • Sex steroids have been postulated to influence pathophysiology of human skin through various skin appendages.
  • The presence of sex steroid receptors has been also reported in adnexal tumors but its details still remained unknown.
  • Therefore, in this study, we immunolocalized sex steroid receptor protein (estrogen receptor (ER)alpha, ERbeta, progesterone receptor (PR)A, PRB and androgen receptor (AR)) in 23 cases of non-pathological skin (male: 10, female: 13) and in 50 cases of skin adnexal tumors (male 24, female 26; 38 benign and 12 malignant).
  • ERalpha immunoreactivity was detected exclusively in basal cells of sebaceous glands of non-pathological skin.
  • In sebaceous gland neoplasms, the number of ERalpha positive cases was significantly lower in skin appendage neoplasms than non-pathological skin.
  • Therefore sex steroids are considered to play important roles in regulation of non-pathological skin appendage function and pathogenesis and/or development of its neoplasm.
  • In addition, the status of the great majority of sex steroid hormone receptors was maintained throughout the process of neoplastic transformation of skin appendages, except for AR and ERalpha in sweat and sebaceous gland neoplasms.

  • [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.
  • 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.

  • [Title] Five new CYLD mutations in skin appendage tumors and evidence that aspartic acid 681 in CYLD is essential for deubiquitinase activity.
  • Brooke-Spiegler syndrome, familial cylindromatosis, and familial trichoepithelioma are autosomal-dominant genetic predispositions for benign tumors of skin appendages caused by mutations in the CYLD gene localized on chromosome 16q12-q13.
  • We investigated five families affected with these skin neoplasms and identified four premature stop codons and the novel missense mutation D681G in a family in which 11 of 12 investigated tumors were trichoepitheliomas.

  • [Title] Adnexal skin tumors in Zaria, Nigeria.
  • BACKGROUND: Adnexal skin tumors share many features in common and differentiate along one line.
  • 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.
  • Forty-six lesions (88.5%) were benign and six (11.5%) malignant.
  • 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] Secretory carcinoma in the axilla: probable origin from axillary skin appendage glands in a young girl.
  • Invasive carcinoma in the axilla may arise from skin appendage glands or ectopic breast tissue or it may be a metastasis.
  • Carcinomas of the skin adnexal glands and breast can be difficult to distinguish from each other as they often display the same patterns of growth.
  • Tubular, cribriform, papillary, apocrine, mucinous, and adenoid cystic are histologic types of carcinoma seen in the breast and skin appendage glands.
  • To our knowledge, secretory carcinoma, the most common form of mammary carcinoma in children, has not yet been described as a morphologic pattern of skin adnexal carcinoma, although we cannot exclude the possibility that such a case was reported with a different diagnosis.
  • We report a case of a young girl with secretory carcinoma that seems to have arisen from skin appendage glands in the skin of the axilla in the absence of demonstrable ectopic breast tissue.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] CYLD mutations in familial skin appendage tumours.
  • BACKGROUND: Germ-line mutations in CYLD are found in patients with familial skin appendage tumours.
  • Brooke-Spiegler syndrome (BSS) is characterised by cylindromas, trichoepitheliomas and spiradenomas, whereas in familial cylindromatosis (FC) patients present with cylindromas and in multiple familial trichoepitheliomas (MFT) with trichoepitheliomas as the only skin tumour type.
  • Although described as distinct entities, recent studies suggest that they are within the spectrum of a single entity.
  • Genotype-phenotype analysis failed to reveal a correlation between the types of mutations and their location within the gene and the patients' phenotypes and disease severity.
  • CONCLUSIONS: This study provides further evidence on the role of CYLD in the pathogenesis of skin appendage tumours characterised by cylindromas, trichoepitheliomas and/or spiradenomas, but the molecular mechanisms of CYLD in skin tumorigenesis and the reasons for phenotypic variability remain to be explored.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Bowen's disease with invasive adnexal carcinoma: the pluripotential nature of Bowen's disease cells.
  • 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.
  • The plaque lesions possessed clinical features typical of Bowen's disease.
  • 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.
  • The present cases support a notion that Bowen's disease maintains a pluripotential nature.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Monoclonal antibody Ber-EP4 reliably discriminates between microcystic adnexal carcinoma and basal cell carcinoma.
  • 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.
  • Only one basal cell carcinoma was weakly positive.
  • Twelve of the 16 desmoplastic trichoepitheliomas were immunoreactive with Ber-EP4 and the staining was more variable than those of basal cell carcinomas.
  • 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.

  • [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.
  • 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.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Bazex-Dupré-Christol syndrome: an ectodermal dysplasia with skin appendage neoplasms.
  • Bazex-Dupré-Christol syndrome is a rare X-linked genodermatosis characterized by early-onset nonmelanoma skin cancers, atrophoderma follicularis, hypotrichosis, hypohidrosis, and multiple milia.
  • We report a 5-year-old child presenting sparse hair, reduced sweating, ice-pick skin depressions of the dorsum of hands, facial and limb milia, perianal skin hyperpigmentation, and hyperpigmented papules of the axillae and neck.
  • Histologic examination of a skin papule obtained from the index case revealed features consistent with trichoepithelioma.
  • Our findings indicate that trichoepitheliomas are an early sign of Bazex-Dupré-Christol syndrome and may guide the diagnosis even before the development of basal cell carcinomas.
  • The high frequency of hypotrichosis, hypohidrosis and dry skin in Bazex-Dupré-Christol syndrome indicates that it may be better classified as an ectodermal dysplasia.
  • Comparison with other conditions combining features of ectodermal dysplasia and proneness to skin tumors suggests the involvement of a common pathogenic pathway implicated in both skin development and cancer.

  • OBJECTIVE: To describe a previously unrecognized, distinctive cutaneous adnexal carcinoma capable of an aggressive clinical course.
  • DESIGN: Clinicopathologic analysis of a series of 12 cases.
  • Histologically, adnexal clear cell carcinoma with comedonecrosis was characterized by dermal proliferation of nests of epithelial cells showing distinctive zonal arrangement.
  • 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.

  • [Title] Rare skin cancer: a population-based cancer registry descriptive study of 151 consecutive cases diagnosed between 1980 and 2004.
  • BACKGROUND: There are few epidemiological data available on rare skin cancer, including Merkel cell carcinoma, Paget's disease, adnexal carcinoma, and sarcoma.
  • We conducted this study to investigate the epidemiology of rare skin cancer diagnosed in the department of Doubs from 1980 to 2004.
  • Diagnosis was based on the 3(rd) edition of the International Classification of Diseases for Oncology.
  • Median age for the diagnosed disease was 63 years.
  • Fifty nine cases (39%) were sarcomas, 35 (23%) adnexal carcinomas, 27 (18%) Merkel cell carcinoma and 27 (18%) Paget's disease.
  • The standardized incidence rates were 0.37/100 000 (0.27-0.47) for sarcomas, 0.16 (0.10-0.22) for adnexal tumors, 0.13 (0.08-0.18) for Merkel cell carcinoma, and 0.15 (0.09-0.21) for Paget's disease.
  • CONCLUSIONS: Our results based on a population-based cancer registry showed an increase of the standardized incidence rate for all types of rare skin tumors.

  • In mammals, the precise arrangement of hair follicles in the skin is due to the amount and distribution of signals that promote and inhibit hair placode formation.
  • Continued development of a hair follicle after placode formation requires a complex cross-talk between the mesenchyme and epidermis.
  • The study of normal hair development may suggest ways to restore or eliminate hair and might identify possible targets for the therapy of basal cell carcinoma, a cancer which strongly resembles embryonic hair follicles.

  • We present the case of a 77-year-old Japanese male with an asymptomatic red nodule on his left cheek.
  • On the basis of these results, we suggested that skin appendage differentiation, particularly sweat glandular differentiation, was present in this case.

  • [Title] Cytologic features of primary malignant tumors of skin and adnexae.
  • STUDY DESIGN: Cases of primary malignant tumors of skin and adnexae diagnosed on cytology with histopathology confirmation were retrieved from case records of 1998-2005.
  • RESULTS: Thirty primary malignant tumors of skin and adnexae were analyzed.
  • Melanoma was the most common (n=12), followed by squamous cell carcinoma (SCC) (n=5).
  • There were 3 basal cell carcinomas and 2 cases each of sebaceous carcinoma, Paget's disease of the breast and lymphoma.
  • There were single cases of eccrine carcinoma, malignant trichilemmal tumor, undifferentiated carcinoma and extramedullary myeloid cell tumor.
  • All the cases of hemopoietic tumors (n=3) and the majority of the cases (4 of 7) of adnexal were seen to arise from head and neck region.
  • CONCLUSION: Cytodiagnosis of primary malignant tumors of skin and adnexae is possible based on morphology and clinical presentation.

  • [Title] [A case of primary mucinous carcinoma with endocrine differentiation of the skin].
  • 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.
  • 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.
  • MCS resembles mammary mucinous carcinoma not only in morphological appearance but also in immunohistochemical phenotypes, such as positive immunoreactivity to gross cystic disease protein fluid-15, MUC2, MUC6, estrogen receptor and progesterone receptor.
  • 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.
  • To clarify the difference and/or similarity between mucinous carcinoma of the breast and MCS, immunohistochemical and cytogenetic analyses of additional cases of MCS are required.

  • [Title] Primary cutaneous neuroendocrine cell carcinoma (Merkel cell carcinoma) with prominent microcystic features, mimicking eccrine carcinoma.
  • Although primary cutaneous neuroendocrine cell carcinoma [Merkel cell carcinoma (MCC)] may show divergent features, including microcystic ('tubuloglandular'), squamous, eccrine and rhabdomyoblastic, a diffuse microcystic pattern is exceedingly rare.
  • In this study, we present two cases of MCC with prominent microcystic features, which precluded a definitive diagnosis in the initial punch biopsy.
  • Punch biopsies from both patients revealed an infiltrating neoplasm with prominent microcystic features that mimick tubuloglandular structures, lined by hyperchromatic basaloid cells, which were strongly positive for chromogranin and BerEP4, variably positive for CK7 and CK5/6 and negative for CK20, synaptophysin, S-100, epithelial membrane antigen (EMA), gross cystic disease fluid protein-15 (GCDFP-15), estrogen/progesterone receptors (ER/PR), thyroid transcription factor 1 (TTF1) and carcinoembryonic antigen (CEA).
  • Although the lack of CK20 staining is unusual, the histologic characteristics along with the remaining immunohistochemical studies favor the diagnosis of a primary cutaneous neuroendocrine cell carcinoma over the variants of eccrine carcinoma or basal cell carcinoma with neuroendocrine differentiation.

  • [Title] Adnexal skin carcinomas of the face.
  • Skin adnexal neoplasms are rare tumors, and knowledge on their exact histological development and pathogenesis remains fragmented.
  • Their diagnosis and management are frequently troublesome, especially for malignant tumors.
  • We present a retrospective case series of malignant appendageal tumors of the face.
  • Records of patients with histologically confirmed adnexal skin carcinoma managed at a single department during the period 1995 to 2004 were reviewed.
  • Patient biodata, surgical management, and main outcome measures such as locoregional recurrence, distant metastasis, and disease-free and overall survival were recorded.Eleven patients were identified from record analysis.
  • Nine of 11 patients were alive and free of local and/or regional disease on final follow-up.
  • Two patients died of causes unrelated to the disease.
  • Clinical and histological features, tumor biological behavior, diagnostic difficulties, and recommended management are discussed.In conclusion, adnexal skin tumors should be considered in the differential diagnosis of skin tumors, particularly in view of their more sinister prognosis compared with other nonmelanoma skin tumors.

  • [Title] Trichilemmal carcinoma of the upper eyelid: a case report.
  • We report a very rare case of trichilemmal carcinoma (TLC) involving the upper eyelid.
  • To the best of our knowledge, this is the first report of trichilemmal carcinoma of the upper eyelid in Korea.
  • A 51-year-old man presented to our hospital complaining of a bloody discharge from his left upper eyelid.
  • A diagnosis of TLC was made, and total excision of the mass and reconstruction of the eyelid were performed.
  • Trichilemmal carcinoma is a rare malignant tumor, though it appears to be an indolent neoplasm with no metastatic potential.
  • The treatment of choice for trichilemmal carcinoma of the eyelid is complete excision with tumor-free margins due to the locally invasive nature of the lesion.

  • BACKGROUND: Desmoplastic trichoepithelioma (DTE) is an uncommon form of adnexal tumour that was described for the first time as a separate clinicopathological entity in 1976.
  • We carried out a retrospective histopathological study of a large series of cases of DTE in order to better characterise this tumour and compare it with sclerodermiform basal cell carcinoma (BCC), which is in fact the most common as well as the most complex type of differential diagnosis.
  • Diagnosis was confirmed by two different examiners and all microscopic elements were reviewed.
  • The diagnosis was only made by the clinician in four cases; in 38 cases the diagnosis made was BCC.
  • A common finding was granulomas with foreign bodies and calcifications.
  • There is a significant association with naevus, a singular feature among adnexal tumours.
  • A suggested clinical diagnosis is thus possible.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] High-grade trichoblastic carcinoma arising in trichoblastoma: a rare adnexal neoplasm often showing metastatic spread.
  • It has been debated whether malignant transformation of trichoblastoma occurs.
  • The concept was recently forwarded that basal cell carcinoma is as a malignant neoplasm of follicular germinative cells and should be named trichoblastic carcinoma to show its relationship to trichoblastoma.
  • Almost all basal cell carcinomas are low-grade malignant neoplasms and develop metastases only very rarely, and if so, only after very long duration and untreated growth.
  • Only rare basal cell carcinomas arise in trichoblastomas.
  • Up to now there have only been two reports of high-grade trichoblastic carcinoma arising in trichoblastoma, showing systemic metastatic spread and death.
  • We add two further cases of trichoblastic carcinoma with anaplastic nuclei, arising in trichoblastoma.
  • The other one was a trichoblastic carcinoma at the base of a trichoepithelioma on the right thigh of an 87-year-old woman with Brooke-Spiegler syndrome.
  • Our cases emphasize that high-grade trichoblastic carcinoma develops via malignant transformation of trichoblastoma, and is very rare.

  • [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.
  • 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%).

  • A 63-year-old man with hepatocellular carcinoma consequent to chronic viral hepatitis C presented with severe dermatitis on the lower right side of the back after transcatheter arterial chemoembolization (TACE) via the 10th intercostal artery, because his hepatic artery had already collapsed due to repeated usage for TACE.
  • The regional skin showed redness and hardness with pustules.
  • Histologically, there was epidermal and appendage necrosis, as well as exocytosis of red blood cells.
  • With a diagnosis of skin injury due to leakage of lipiodol ultrafluid, mitomycin, and epirubicin, administered via the 10th intercostal artery, onto the skin tissue, topical application of 0.06% fluocinonide-containing cream was prescribed.
  • After several weeks of conservative local treatment, the leakage skin injury improved significantly, leaving pigmentation, hardness, and a small necrotic mass, as reported elsewhere (Honda T, Matsushima S, Fujii S, et al.
  • A case of skin injury following transcatheter arterial chemotherapy through intercostal artery for hepatocellular carcinoma.
  • Skin Res 2003; 2: 18-22).
  • Subsequently, the patient again consulted the Dermatology Department with further dermatitis in an almost identical skin region on the right side of the abdomen (irregularly spreading erythematous and edematous eruptions with itching; Fig. 1).
  • The medical records showed that the patient had received 16 ultrasonic examinations with the same ultrasonic gel before the leakage skin injury.
  • The 19th examination was performed using Sono Jelly, which contains no PG, and no skin problems were observed.

  • [Title] Squamous cell carcinoma with clear cells: how often is there evidence of tricholemmal differentiation?
  • Clear-cell carcinoma of the skin was described by Kuo in 1980 as a cutaneous tumor composed of clear cells that lacked cytoplasmic glycogen or evidence of tricholemmal keratinization.
  • Tricholemmal carcinoma (TC) is conventionally considered to be a neoplasm derived from adnexal keratinocytes with glycogenated clear cells and evidence of outer root sheath or tricholemmal differentiation.
  • The existence of TC has been questioned as it has been argued that without clear immunohistochemical evidence of outer root sheath differentiation, TC cannot be distinguished from clear-cell carcinoma of the skin.
  • Our laboratory has not routinely stained the cases that appear to be carcinomas with clear keratinocytes to determine if glycogen is present and has not made the diagnosis of TC.
  • We sought to test whether the presence of glycogen, light microscopic features said to be typical of TC, or immunohistochemical findings would delineate a group of "true" TC among the cases that we have been recording as squamous cell carcinomas with clear cells (SCC-C).
  • 40 cases of SCC-C were evaluated for 7 histologic and histochemical criteria (a lobular arrangement, peripheral palisading, tricholemmal keratinization, folliculocentricity, evidence of a preexisting tricholemmoma, the presence of intracytoplasmic glycogen, and a thickened basement membrane) said to characterize TC.
  • Overall, the carcinomas showed a spectrum of the above aggregated criteria ranging from 0 to 5.
  • The glycogen-free clear-cell carcinoma described by Kuo seems uncommon in our patient population.

  • 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.
  • Seventy percent of the tumors were wrongly diagnosed initially as basal cell carcinoma.
  • 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] Differential expression of mucin core proteins and keratins in apocrine carcinoma, extramammary Paget's disease and apocrine nevus.
  • BACKGROUND: Apocrine carcinomas are rare, the immunohistochemical characterizations that are incomplete.
  • The purpose of this study was to determine the immunohistochemical characteristics of mucin core proteins and keratins in apocrine carcinoma, extramammary Paget's disease (EMPD) and apocrine nevus.
  • METHODS: We report four cases of apocrine carcinomas along with immunohistochemical analyses: (i) an axillary apocrine carcinoma with an apocrine nevus, (ii) an inguinal apocrine carcinoma, (iii) a vulvar apocrine carcinoma with EMPD and (iv) an axillary apocrine carcinoma with EMPD and an apocrine nevus.
  • RESULTS: The tumor cells of apocrine carcinomas, EMPD and apocrine nevi displayed a positive reaction to MUC-1 and CK7 and a negative reaction to CK20.
  • Apocrine carcinomas had high molecular weight (HMW) cytokeratin(+)/CK5(+)/CK14(-)/MUC5AC(-), EMPD with underlying apocrine carcinoma had HMW cytokeratin(-)/CK5(-)/CK14(-)/MUCA5AC(-) and the apocrine nevi had HMW cytokeratin(+)/CK5(+)/CK14(+)/MUCA5AC(+).
  • CONCLUSION: The immunohistochemical findings suggest that apocrine carcinomas, apocrine nevi and EMPD with underlying apocrine carcinomas are quite different, even though they are all derived from apocrine glands.

MedlinePlus Health Information. consumer health - Skin Cancer.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Hybrid skin adnexal tumors are common, and spiradenocylindroma is well described.
  • OBJECTIVE: However, malignant transformation in this setting is infrequent, especially resemblance to lymphoepithelioma-like carcinoma of skin, which is not associated with Epstein-Barr virus.
  • METHODS: A 65-year-old female presented with ataxia and a skin nodule composed of a hybrid adnexal tumor (spiradenoma and cylindroma) that transitioned into an undifferentiated carcinoma with attendant lymphocytes and plasma cells.
  • RESULTS: The undifferentiated component resembled a lymphoepithelioma-like carcinoma and showed focal evidence of tubular and squamous differentiation.
  • CONCLUSION: This case highlights the transition of a benign hybrid tumor (spiradenocylindroma) into a spiradenocarcinoma that resembled lymphoepithelioma-like carcinoma of skin.

  • [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.
  • 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.
  • One of the most challenging diagnoses in dermatopathology is differentiating morphoeic basal cell carcinoma from desmoplastic trichoepithelioma.
  • 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.
  • RESULTS: All 17 desmoplastic trichoepitheliomas were immunoreactive with > 80% of the cells stained, whereas 12 of the 14 (86%) morphoeic basal cell carcinomas were p75NTR negative.
  • In the two positive cases of morphoeic basal cell carcinoma < 30% of cells were labelled.
  • 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] An unusual composite pilomatrix carcinoma with intralesional melanocytes: differential diagnosis, immunohistochemical evaluation, and review of the literature.
  • We report a case of an extremely rare histologic combination of pilomatrix or pilomatrical carcinoma with admixed melanocytes within the same tumor mass.
  • Pilomatrix carcinoma is a neoplasm of low-grade malignancy that is characterized by a tendency for recurrence but low risk of metastasis.
  • In addition, intermingled with the pilomatrix carcinoma, several easily identified pigmented cells with dendritic processes were present singly and as small aggregates.
  • Pilomatrix carcinoma with melanocytes should be distinguished from the conventional pilomatrixoma with pigmentation, melanocytic matricoma, melanoma, and pigmented basal cell carcinoma with matrical differentiation.
  • Clinicians and pathologists should be aware of the occurrence of pilomatrix carcinoma with melanocytes because of its potential for diagnosis as melanoma.

  • [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.
  • 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.

  • 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.
  • 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.

  • MATERIAL AND METHODS: A total of 30 cases of benign tumours of cutaneous appendages originating from the hair follicle and 30 cases of basal cell carcinoma were retrieved from the archives deposited from 2004 to 2008.
  • However, peripheral CD10 of basal cell carcinoma was stronger than the other for [1+] immunopositivity (p = 0.03).
  • CONCLUSIONS: CD10 may be very useful for the differential diagnosis between them particularly in the small and superficial biopsies and it may be even a life-saving method in some selected cases.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Cutaneous appendageal carcinoma incidence and survival patterns in the United States: a population-based study.
  • OBJECTIVE: To examine incidence patterns of patients diagnosed as having cutaneous appendageal carcinoma (CAC).
  • RESULTS: Cutaneous appendageal carcinomas are uncommon (age-adjusted IR, 5.1 per 1 million person-years), with the IR among men statistically significantly higher than women (6.3 vs 4.2, respectively; male to female IR ratio 1.51; P < .001).
  • Apocrine-eccrine carcinoma overall was the most common category (IR, 2.6), and the IR was highest among non-Hispanic white (IR, 2.8) compared with other ethnic/racial groups (P < .001).
  • Cutaneous appendageal carcinomas IRs rose 100-fold with age, from 0.37 among those aged 20 to 29 years to 37.3 among those 80 years or older.
  • From 1978-1982 to 2002-2005, the CAC IRs increased 150%, from 2.0 to 5.0; the apocrine-eccrine carcinoma and the sebaceous carcinoma IRs rose 170%, from 1.0 to 2.7, and 217%, from 0.6 to 1.9, respectively.
  • Five-year relative survival rates overall were 99% for localized and 43% for distant disease.
  • CONCLUSIONS: Cutaneous appendageal carcinomas are rare tumors with IRs that vary by sex and racial/ethnic group.
  • Cutaneous appendageal carcinoma IRs are increasing in the United States, especially for sebaceous carcinoma, perhaps related to improved recognition and classification, but factors such as UV exposure and immunosuppression may also play a role.

  • METHODS: We evaluated expression of follicular stem-cell markers, cytokeratin (CK) 15 and nestin, in 78 benign and 23 malignant adnexal neoplasms.
  • 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.
  • Reinforcing this and a novel finding of our study is the preferential expression of nestin in myoepithelial cells of these lesions.

  • This approach appears to be superior to conventional surgical excision in the treatment of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), the two most common cancers of the skin.
  • Its efficacy in treating BCC and SCC has led clinicians to explore the role of Mohs micrographic surgery in the management of less common cutaneous neoplasms, such as melanoma, Merkel cell carcinoma, dermatofibrosarcoma protuberans, extramammary Paget's disease, and microcystic adnexal carcinoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Trichilemmal carcinoma arising in seborrheic keratosis: a case report and published work review.
  • The secondary skin malignancies arising in seborrheic keratosis (SK) are uncommon, and the causal association between the pre-existing lesion and subsequent malignant transformation remains uncertain.
  • Among these enigmatic conditions, trichilemmal differentiation and/or neoplasms in SK have rarely been reported thus far.
  • Herein, we describe a case of invasive trichilemmal carcinoma arising in a long-standing SK of the abdominal skin, and clinicopathologically review this rare complication with a computerized medical published work search (PubMed) and citations from earlier reports.
  • To our knowledge, only four cases of trichilemmal tumors arising in SK have been observed, and, interestingly, all cases, including ours, were Japanese.
  • Four of five cases (80%) developed the tumors in non-sun-exposed SK, and indeed had no apparent actinic damage in the histology.
  • The pre-existing SK itself is more likely to act as the primary pathogenic event for developing the secondary trichilemmal tumors than a coincidental phenomenon and a consequence of skin damage by cumulative sun exposure.

  • All mammary and extramammary Paget's disease were labeled with CD23.
  • In comparison, pagetoid Bowen's disease, melanoma in situ and sebaceous carcinoma exhibited negative staining.
  • In addition, CD23 reacted diffusely with cutaneous mucinous eccrine carcinoma in a manner similar to breast or colonic adenocarcinoma.
  • CD23 is a useful addition to the diagnostic immunohistochemical panels for Paget's disease.

  • Extramammary Paget's disease is a rare cutaneous adenocarcinoma of epidermal origin, which is frequently associated with adnexal carcinoma and internal malignant conditions.
  • Clinically, extramammary Paget's disease is characterized by a red, moist, eroded plaque in the anogenital region.
  • Extramammary Paget's disease usually behaves as a slow-growing intraepithelial adenocarcinoma; however, it may become invasive and may metastasize through dermal lymphatics.
