  • [Title] Characterization of breast precancerous lesions and myoepithelial hyperplasia in sclerosing adenosis with apocrine metaplasia.
  • The strategy we have been pursuing to identify early apocrine breast lesions is based on the postulate that invasive apocrine carcinomas evolve from epithelial cells in terminal duct lobular units (TDLUs) in a stepwise manner that involves apocrine metaplasia of normal breast epithelia, hyperplasia, atypia, and apocrine carcinoma in situ.
  • First, we identify specific protein biomarkers for benign apocrine metaplasia and thereafter we search for biomarkers that are highly overexpressed by pure invasive apocrine carcinomas.
  • Here we present studies in which we have used antibodies against components of a benign apocrine signature that includes 15-prostaglandin dehydrogenase (15-PGDH), a protein that is expressed by all benign apocrine lesions, and markers that are highly overexpressed by pure invasive apocrine carcinomas such as MRP14 (S100A9), psoriasin (S100A7), and p53 to identify precancerous lesions in sclerosing adenosis (SA) with apocrine metaplasia.
  • The latter is a benign proliferative lesion of the breast that exhibits an increase in the size of the TDLUs and characterized by retained two-cell lining, and myoepithelial (ME) and stromal hyperplasia.
  • SA with apocrine metaplasia, i.e. apocrine adenosis (AA), presents with a higher degree of atypical apocrine hyperplasia, and these lesions are believed to be precursors of apocrine carcinoma, in situ and invasive.
  • Analysis of 24 selected SA samples with apocrine metaplasia revealed non-obligate putative apocrine precancerous lesions that displayed some, or in same cases all the three markers associated with pure invasive apocrine carcinomas.
  • These studies also revealed p53 positive, non-apocrine putative precancerous lesions as well as novel phenotypes for ME and some luminal cells characterized by the expression of cytokeratin 15.

  • [Title] Apocrine cysts of the breast: biomarkers, origin, enlargement, and relation with cancer phenotype.
  • Here we present an extensive proteomic and immunohistochemistry (IHC) study of breast apocrine cystic lesions aimed at generating specific biomarkers and elucidating the relationship, if existent, of apocrine cysts with cancer phenotype.
  • To this end we compared the expression profiles of apocrine macrocysts obtained from mastectomies from high risk cancer patients with those of cancerous and non-malignant mammary tissue biopsies collected from the same patients.
  • We identified two biomarkers, 15-hydroxyprostaglandin dehydrogenase and 3-hydroxymethylglutaryl-CoA reductase, that were expressed specifically by apocrine type I cysts as well as by apocrine metaplastic cells in type II microcysts, terminal ducts, and intraductal papillary lesions.
  • IHC analysis of the corresponding 93 primary tumors indicated that most apocrine changes have little intrinsic malignant potential, although some may progress to invasive apocrine cancer.
  • None of the apocrine lesions examined, however, seemed to be a precursor of invasive ductal carcinomas, which accounted for 81% of the tumors analyzed.
  • Our studies also provided some insight into the origin, development, and enlargement of apocrine cysts in mammary tissue.
  • The successful identification of differentially expressed proteins that characterize specific steps in the progression from early benign lesions to apocrine cancer opens a window of opportunity for designing and testing new approaches for pharmacological intervention, not only in a therapeutic setting but also for chemoprevention, to inhibit cyst development as both 15-hydroxyprostaglandin dehydrogenase and 3-hydroxymethylglutaryl-CoA reductase are currently being targeted for chemoprevention strategies in various malignancies.

  • [Title] Molecular characterization of apocrine carcinoma of the breast: validation of an apocrine protein signature in a well-defined cohort.
  • Invasive apocrine carcinomas (IACs), as defined by morphological features, correspond to 0.3-4% of all invasive ductal carcinomas (IDC), and despite the fact that they are histologically distinct from other breast lesions there are currently no standard molecular criteria available for their diagnosis and no unequivocal information as to their prognosis.
  • In an effort to address these concerns we have been using protein expression profiling technologies in combination with mass spectrometry and immunohistochemistry (IHC) to discover specific biomarkers that could allow us to molecularly characterize these lesions as well as to dissect some of the steps in the processes underlying breast apocrine metaplasia and development of precancerous apocrine lesions.
  • Establishing these apocrine-specific markers as best practice for the routine pathology evaluation of breast cancer, however, will require their validation in large cohorts of patients.
  • Towards this goal we have composed a panel of antibodies against components of an apocrine protein signature that includes probes against the apocrine-specific markers 15-prostaglandin dehydrogenase (15-PGDH), and acyl-CoA synthetase medium-chain family member 1 (ACSM1), in addition to a set of categorizing markers that are consistently expressed (AR, CD24) or not expressed (ERα, PgR, Bcl-2, and GATA-3) by apocrine metaplasia in benign breast lesions and apocrine sweat glands.
  • This panel was used to analyze a well-defined cohort consisting of 14 apocrine ductal carcinoma in situ (ADCIS), and 33 IACs diagnosed at the Cancer Institute Hospital, Tokyo between 1997 and 2001.
  • Samples were originally classified on the basis of cellular morphology with all cases having more than 90% of the tumour cells exhibiting cytological features typical of apocrine cells.
  • Using the expression of 15-PGDH and/or ACSM1 as the main criterion, but taking into account the expression of other markers, we were able to identify unambiguously 13 out of 14 ADCIS (92.9%) and 20 out of 33 (60.6%) IAC samples, respectively, as being of apocrine origin.
  • Our results demonstrate that IACs correspond to a distinct, even if heterogeneous, molecular subgroup of breast carcinomas that can be readily identified in an unbiased way using a combination of markers that recapitulate the phenotype of apocrine sweat glands (15-PGDH(+), ACSM1(+), AR(+), CD24(+), ERα(-), PgR(-), Bcl-2(-), and GATA-3(-)).

  • [Title] 15-prostaglandin dehydrogenase expression alone or in combination with ACSM1 defines a subgroup of the apocrine molecular subtype of breast carcinoma.
  • The remaining 10% include rarer types such as tubular, cribriform, mucinous, papillary, medullary, metaplastic, and apocrine breast carcinomas.
  • An additional subclass termed "molecular apocrine" has recently been described, but these lesions did not exhibit all the histopathological features of classical invasive apocrine carcinomas (IACs).
  • By comparing the protein expression profiles of apocrine macrocysts and non-malignant breast epithelial tissue we have previously reported the identification of a few proteins that are specifically expressed by benign apocrine lesions as well as by the few IACs that were available to us at the time.
  • Here we reiterate our strategy to reveal apocrine cell markers and present novel data, based on the analysis of a considerably larger number of samples, establishing that IACs correspond to a distinct molecular subtype of breast carcinomas characterized by the expression of 15-prostaglandin dehydrogenase alone or in combination with a novel form of acyl-CoA synthetase medium-chain family member 1 (ACSM1).

  • [Title] Benign breast biopsy diagnosis and subsequent risk of breast cancer.
  • BACKGROUND: We examine benign breast biopsy diagnoses as reported by community pathologists in New Mexico and investigate associations with future breast cancer development.
  • METHODS: Using data collected between 1992 and 2000 by the New Mexico Mammography Project and cancer data through 2003 from the New Mexico Tumor Registry, we calculated breast cancer rates following 14,602 benign breast biopsies for women ages 30 to 89 years.
  • RESULTS: We identified 480 subsequent breast cancer diagnoses among 14,602 women with benign breast biopsies and 4,402 breast cancer diagnoses among 215,283 women with mammograms assigned a "negative" or "benign finding" assessment.
  • Among low-risk histologic diagnoses, the strongest associations with subsequent breast cancer development included adenosis, apocrine metaplasia, calcifications, and ductal hyperplasia.
  • CONCLUSIONS: The observed breast cancer occurrence contributes to evidence of increased risk following benign biopsy.

  • [Title] Diagnostic significance of the immunoexpression of CD34 and smooth muscle cell actin in benign and malignant tumors of the breast.
  • PURPOSE: Our aim was to investigate the distribution of CD34 and smooth muscle cell actin positive myofibroblasts in the stroma of the normal mammary gland, benign and malignant tumors.
  • RESULTS: We have found normal breast tissue, sclerosing adenosis, fibroadenomas, fibrocystic diseases, phyllodes tumor, DCIS, ductal invasive, lobular, squamous, medullary, mucinous, and papillary carcinomas.
  • We also found apocrine metaplasia, florid ductal hyperplasia, atypical hyperplasia, papilloma and LCIS associated with the malignant tumors.
  • All the normal breast tissues and most of benign lesions were positive for CD34 and negative for SMA.
  • The exceptions were represented by a case of fibroadenoma and the phyllodes tumor, with CD34 positivity and a focal acquisition of SMA; fibrocystic disease with associated apocrine metaplasia adjacent to a squamous carcinoma with loss of CD34 expression and focal acquisition of SMA.
  • CONCLUSIONS: Although there were some exceptions especially when one of the two markers was interpreted separately and in some cases associated with sclerotic stroma, we conclude that the combined expression of CD34 and a-SMA is of potential diagnostic value in the distinction between benign and malignant tumors in some difficult cases.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Apocrine hidrocystoma of the cheek.
  • BACKGROUND: Apocrine hidrocystoma is an uncommon benign cystic proliferation of the apocrine sweat glands.
  • An exocrine tumor or, more unlikely, a melanoma was considered as a differential diagnosis.
  • Pathologically, the lesion was determined to be an apocrine hidrocystoma.
  • CONCLUSIONS: This benign lesion can be excised by a narrow margin.
  • Therefore, knowledge of this benign entity in head and neck surgery including the differential diagnosis can prevent an unnecessarily large defect by too large margins.

  • [Title] Cell turnover in apocrine metaplasia and apocrine adenosis of the breast.
  • Apocrine metaplasia (APM) is a common finding in the breast of postmenopausal women and is seen in a broad spectrum of lesions ranging from microscopic cysts to invasive apocrine carcinoma.
  • Apocrine metaplasia within sclerosing adenosis is known as apocrine adenosis (AA) and is considered a benign lesion of the breast.
  • Apocrine metaplasia and AA have been the subject of many studies; however, little is known about the dynamics of cell turnover in these lesions.

  • [Title] Cytokeratin 15 expression in apocrine mixed tumors of the skin and other benign neoplasms with apocrine differentiation.
  • To clarify the features of apocrine mixed tumors (AMT) of the skin among benign neoplasms with apocrine differentiation in their relationship to follicular stem cells, we investigated the immunohistochemical expression of CK15 (LHK15 and C8/144B), which is a relatively specific marker of hair follicle stem cells in the bulge, in 35 cases of eight different benign neoplasms with presumed apocrine differentiation.
  • All eight cases of AMT of the skin showed CK15 immunostaining of the neoplastic cells, and all four cases of syringocystadenoma papilliferum, all five cases of spiradenoma, and both cases of cylindroma also showed a focally positive reaction to CK15.
  • None of the other benign neoplasms with presumed apocrine differentiation showed CK15 expression.
  • In AMT of the skin, the proportion of CK15-positive cells in the follicular or sebaceous differentiation group (78.8%, average of four cases) was significantly higher than the group without this differentiation (8.8%, average of four cases).
  • AMT of the skin are unique among benign neoplasms with apocrine differentiation in their substantial and constant CK15 expression, suggesting that they derive from multipotent epithelial stem cells in the bulge.
  • AMT of the skin with follicular or sebaceous differentiation are considered to show an immature stage of apocrine differentiation still rich in stem cells or to originate from stem cells with an incompletely established apocrine fate.
  • The partially positive reaction for CK15 in syringocystadenomas papilliferum and spiradenoma/cylindroma may depend on the ability to express CK15 in stem cells with an apocrine fate or result from the follicular and apocrine nature of this neoplasm.

  • [Title] Fine-needle aspiration cytologic features of four special types of breast cancers: mucinous, medullary, apocrine, and papillary.
  • Recognition of special types of breast cancers by fine-needle aspiration (FNA) cytology may have prognostic implications but some difficulties still exist in the ability of cytopathologists to determine the tumor subtypes.
  • Papillary carcinomas were also compared with 10 benign papillary lesions.
  • In mucinous carcinoma, the frequency of signet ring cells (62.5%), and background pools of mucin (87.5%) were significantly higher than those of duct cell carcinoma (NOS), medullary carcinoma, apocrine carcinoma, and papillary carcinoma (P = 0.0408 to < 0.0001).
  • In medullary carcinomas, lymphomononuclear cell infiltration (100.0%) was observed in significantly higher number of cases than in papillary, mucinous, and apocrine types (P < 0.0001).
  • Abnormal apocrine cells and papillary formation, characterizing all the apocrine carcinomas and papillary carcinomas, respectively, were present in significantly lower number in other variants and in duct cell carcinoma (NOS) (P = 0.0002 to <0.0001).
  • Glycogen vacuoles (63.6%) were observed in a significantly higher number of papillary carcinoma as compared to duct cell carcinoma (NOS), apocrine, and medullary carcinomas (P = 0.0047 to 0.0022).
  • The significant parameters differentiating papillary carcinoma and benign papillary lesions were loose cohesive clusters (P = 0.001) and acinar formation by neoplastic cells (P = 0.0237).
  • Histopathology reports available in 36 cases, confirmed the cytodiagnosis of carcinoma in all 35 cases and the benign lesion in one case.
  • Thus, special and unusual variants of duct cell carcinomas like mucinous, medullary, apocrine, and papillary have specific cytomorphological features, which differentiate them from one another and from duct cell carcinoma (NOS).
  • However, differentiating features between papillary carcinoma and benign papillary lesions were very few in this study.

  • Although some adnexal neoplasms that develop in association with a nevus sebaceus may exhibit conjoint sebaceous, follicular, or apocrine differentiation, reflecting close embryological relations of the folliculosebaceous-apocrine unit, the feature we report on has not previously been described to the best of our knowledge.

  • [Title] Apocrine mixed tumors of the skin with architectural and/or cytologic atypia: a retrospective clinicopathologic study of 18 cases.
  • We present a series of 18 atypical apocrine mixed tumors of the skin characterized by architectural and/or cytologic atypia but which nevertheless do not qualify these lesions as carcinomas.
  • There were 15 males and 3 females, and all but 1 presented with solitary nodules ranging in size from 4 to 20 mm; 1 female had a large tumor of 12 cm.
  • Overall, the lesions manifested a rather benign architecture, usually with good circumscription, lack of capsular breach or hypercellularity; however, some asymmetry, focally irregular infiltrationlike or pushing tumorous borders were seen.
  • As controls, 4 authentic malignant mixed tumors were studied, but these likewise tested negative for HER-2/neu protein expression and showed no gene amplification; 1 malignant mixed tumor had polysomy 17.
  • We conclude that some atypical cytoarchitectural features in apocrine mixed tumors, albeit worrisome, do not indicate a malignant change.

  • [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.
  • 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.

  • [Title] Adenosis tumor of anogenital mammary-like glands: a case report and demonstration of clonality by HUMARA assay.
  • In mammary pathology, adenosis tumor is defined as a clinically recognizable lesion that histologically primarily consists of adenosis, but also exhibits various combinations of diverse epithelial changes seen in other benign breast diseases.
  • A lesion that occurred in the anogenital area of a 46-year-old woman and apparently arose in anogenital mammary-like glands is described and which, in our opinion, is best classified as adenosis tumor.
  • Several histological patterns within the same tumor mass were recognizable: sclerosing adenosis-like changes, variably sized microcysts and cysts, some with rare short papillary projections having hyalinized cores, rare tubular structures exhibiting epithelial features reminiscent of simple ductal hyperplasia, areas with oxyphilic (apocrine) metaplasia, and clear cell epithelial changes resembling mucinous metaplasia.
  • The cells in the oxyphilic (apocrine) metaplasia areas stained for mitochondrial antigen and Bcl-2.
  • As our case exhibited a number of patterns identical to those seen in diverse benign breast diseases, its classification as adenosis tumor seems justifiable.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • In our routine practice, we observed that CD23 reacted strongly with eccrine and apocrine secretory coils.
  • METHODS: Immunohistochemical staining of CD23 was performed in a total of 131 cases of apocrine, eccrine, follicular and other cutaneous non-lymphoid tumors.
  • RESULTS: CD23 expression was detected in all benign apocrine tumors and in half of benign eccrine tumors, particularly those derived from secretory coils.
  • CD23 staining was seen in 42% (8/19) of microcystic adnexal carcinoma (MAC), while no staining was observed in tumor cells of desmoplastic trichoepithelioma, morpheaform basal cell carcinoma and syringoma.
  • CONCLUSION: CD23 appears to be a reliable immunohistochemical marker of the eccrine/apocrine secretory coil and helpful in identifying sweat gland tumors of such origin.

NCI CPTC Antibody Characterization Program. NCI CPTC Antibody Characterization Program .

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: The overlap in histopathologic features and immunoprofile of eccrine and apocrine neoplasms confounds basic issues relating to lineage of these entities.
  • 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).
  • 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] Granular cell tumor of the breast: a case report and review of literature.
  • Histological evaluation revealed a rare benign neoplasm - granular cell tumor.Granular cell tumor is rare neoplasm that may arise in virtually any body site, and in 5% it occurs in the breast.
  • The histogenesis of this tumor is still rather controversial and currently the most acceptable theory is a Schwann cell origin.
  • The main histological feature is granular cytoplasm of the tumor cells.From a clinical point of view there is a similarity between granular cell tumor and mammary carcinoma on mammography and ultrasound.
  • Pathohistologically, sometimes, differential diagnostic difficulties exist concerning apocrine carcinoma, histiocytic lesions and metastatic neoplasms.

  • 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.

Genetic Alliance. consumer health - Syringoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • INTRODUCTION: Chondroid syringoma is a rare skin tumor that presents as a slow growing, indolent lesion, that is more frequent in male adults and is usually benign.
  • It can be classified as eccrine and apocrine according to its pathological characteristics.
  • Five of the eight cases were apocrine, one of them with follicular and sebaceous differentiation.
  • DISCUSSION: The chondroid syringoma is usually a small-sized skin tumor, frequently on the head and neck.
  • As a general rule, it is a benign tumor.
  • Some authors have proposed the term of atypical mixed tumor of the skin for those chondroid syringomas with histological traits of malignancy but without evidence of metastasis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVE: To study the differences in ultrastructural findings between prostatic carcinoma and benign prostatic hypertrophy, and the various ultrastructural features seen in moderately to poorly differentiated prostatic carcinoma.
  • In contrast to that seen in benign prostatic hypertrophy, the ultrastructural findings of the tumor cells commonly seen in prostatic carcinoma included the centrally located giant nucleoli, a direct contact with stroma, and formation of cytoplasmic microcyst.
  • Similar to their counterparts in benign prostatic cells, prostasomes and storage vesicles in prostatic carcinoma cells were formed in the Golgi apparatus and released into the lumen by apocrine excretion and exocytosis.
  • CONCLUSIONS: Electron microscopy is helpful in distinguishing between benign and malignant prostatic lesions.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • OBJECTIVES: To estimate whether breast uptake of (99m)Tc-(V)DMSA and (99m)Tc-sestamibi in usual ductal epithelial breast hyperplasia (UDH) and apocrine metaplasia is related to cell proliferation rate (Ki-67) and oestrogen receptor (ER) expression, both of which are associated with the potential risk of evolving to malignancy.
  • METHODS: Among patients referred for suspicious breast findings on palpation and/or mammography and evaluated preoperatively with both radiopharmaceuticals, we retrospectively studied 17 (10 with UDH: group I; and seven with apocrine metaplasia: group II).
  • This could prove useful in identifying women with benign but high-risk breast pathologies who might benefit from chemoprophylaxis.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Increasingly more coherent data on the molecular characteristics of benign breast lesions and breast cancer precursors have led to the delineation of new multistep pathways of breast cancer progression through genotypic-phenotypic correlations.
  • The ER-negative group is more complex and heterogeneous, comprising distinct molecular entities, including basal-like, HER2 and molecular apocrine lesions.

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.
  • Overlying skin was normal, and the swelling was fixed to the skin but freely mobile over underlying structure.

Genetic Alliance. consumer health - Syringoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • We performed excisional biopsy of the lesion and lateral advancement skin flap for reconstruction of the skin defect.
  • Chondroid syringoma is a rare skin tumor that occurs, very rarely, in the eyelids, especially the lower eyelid.
  • Chondroid syringomas are classified as two types, the apocrine type characterized by tubular and cystic branching lumina lined by two layers of epithelial cells, and the eccrine type, which has small tubular lumina lined by a single layer of epithelial cells.
  • The tumor can have benign, atypical, and malignant variants.
  • Our patient had the atypical variant, which is characterized by benign cytological features, as well as the presence of infiltrative margins and/or satellite nodules.
  • Even benign chondroid syringomas, if incompletely excised, can recur with malignant transformation; thus, complete excision and regular follow-up is recommended for all chondroid syringomas.

MedlinePlus Health Information. consumer health - MRI Scans.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Magnetic resonance imaging (MRI) of the breast has become important not only for assessing the extent of breast cancer for breast-conserving surgery but also for the evaluation and diagnosis of other benign and malignant pathologies.
  • We will illustrate the MRI features of various breast pathologies including malignant tumors such as invasive and noninvasive ductal carcinoma, special types of invasive carcinoma (mucinous, apocrine, lobular carcinoma, spindle cell carcinoma, and so on), inflammatory carcinoma, semimalignant tumor (phyllodes tumor), benign tumors (fibroadenoma, intraductal and intracystic papilloma), inflammatory conditions, and postsurgical changes.

49. Barbarino S, McCormick SA, Lauer SA, Milman T: Syringocystadenoma papilliferum of the eyelid. Ophthal Plast Reconstr Surg; 2009 May-Jun;25(3):185-8
Genetic Alliance. consumer health - Syringocystadenoma papilliferum.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • PURPOSE: To describe 6 patients with syringocystadenoma papilliferum of the eyelid and to review the literature regarding this rare eyelid tumor.
  • The PubMed database was searched for reported cases of syringocystadenoma papilliferum of the eyelid (keywords: syringocystadenoma, eyelid, apocrine, eccrine).
  • Nine lesions (64%) were associated with apocrine, eccrine, or sebaceous tumors or malformations.
  • None of the lesions was associated with a malignant neoplasm.
  • CONCLUSIONS: Syringocystadenoma papilliferum can rarely affect eyelid skin.
  • Although syringocystadenoma papilliferum of the eyelid can be associated with other benign lesions, no malignant transformation or association with malignant neoplasms has been reported.
  • The evidence suggests that this tumor should be managed with conservative complete excision.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • Each presented clinically with a small, solitary tumor in the anogenital region.
  • This finding could be likened to apocrine metaplasia, a term used in breast pathology.
  • Other histopathological findings observed in this series, analogous to benign breast disease, included sclerosing adenosis-like changes, atypical apocrine adenosis-like changes, changes corresponding to usual ductal epithelial hyperplasia, epitheliomatosis with a streaming growth pattern, lamprocyte-like changes, clear cell change of the myoepithelium, foamy histiocyte reaction, and stromal fibrosis.
  • Oxyphilic metaplasia, areas with solid growth, and changes simulating atypical apocrine adenosis are rare and poorly recognized in hidradenoma papilliferum and may cause diagnostic difficulties; in our cases several submitting pathologists suspected malignancy.
  • The exact role of the HPV in etiology and pathogenesis of this neoplasm has yet to be determined.
