Diagnosis
• Mammary Analogue Secretory Carcinoma (MASC) •? Primary salivary gland origin v. primary cutaneous tumor
• Rule out metastasis
![Page 14: Mammary Analogue Secretory Carcinoma of Salivary Gland … Conf PDFs/23 B - Sat Case...sweat duct tumor (solid and cystic hidradenoma) First, one sees bland-appearing tumors which](https://reader035.vdocument.in/reader035/viewer/2022063020/5fe339d4cea21850e3687b64/html5/thumbnails/14.jpg)
Background
• MASC first described in 2010 by Skalova et al.
• Morphologic overlap between acinic cell carcinoma and secretory carcinoma of the breast
• Tumors affect all ages (range 14-77), slightly male-predominant
![Page 15: Mammary Analogue Secretory Carcinoma of Salivary Gland … Conf PDFs/23 B - Sat Case...sweat duct tumor (solid and cystic hidradenoma) First, one sees bland-appearing tumors which](https://reader035.vdocument.in/reader035/viewer/2022063020/5fe339d4cea21850e3687b64/html5/thumbnails/15.jpg)
MASC
• Presents as slowly growing mass, often near parotid gland
• No evidence of primary cutaneous origin, as of yet
• Most treated with non-radical excision +/-radiotherapy
• Cases of lymph node metastases, local recurrences, low mortality Chiosea et al, Histopathology 2012

Histology of MASC
• Unencapsulated, lobulated
• Intercalated duct cells in tubular, microcystic, papillary patterns
• Lumina with ample “bubbly” secretions (mucicarmine +)
• Absence of serous acinar granules

Fusion Gene
• Almost all MASC had fusion gene ETV6-NTRK3
Normal Cells No ETV6 Split Signals Abnormal ETV6 split signals

Clinical Course
• Patient had neoplasm completely excised by the ENT service
• Work-up for primary underlying neoplasm is on-going and imaging studies are negative for primary salivary gland tumor
![Page 22: Mammary Analogue Secretory Carcinoma of Salivary Gland … Conf PDFs/23 B - Sat Case...sweat duct tumor (solid and cystic hidradenoma) First, one sees bland-appearing tumors which](https://reader035.vdocument.in/reader035/viewer/2022063020/5fe339d4cea21850e3687b64/html5/thumbnails/22.jpg)
Summary
• MASC is likely an under-recognized diagnosis and can present a diagnostic pitfall, easily being confused with a primary adnexal tumor given that it is a newly-described entity and too bland to be immediately interpreted as a metastasis or recurrence. The origin of this particular tumor is still uncertain, as no salivary gland primary has been detected in this patient.
• Immunohistochemical stains for S100, CK7, p63, cytokeratin 5/6, mammaglobin, and identification of the ETV6-NTRK3 fusion gene would be required to completely evaluate tumors of this type
• ? Primary cutaneous/subcutis MASC v. unusual primary apocrine sweat duct tumor (solid and cystic hidradenoma)

Cutaneous Metastases v. Primary Adnexal Carcinoma
• Histopathologic Characteristics of Metastases •Tumor growth often concentrated in the deep dermis - “bottom heavy” appearance
•Sparing of epidermis common •Ulceration and pagetoid spread rarely noted (colonic and melanoma)
•Tumor necrosis sometimes present
•Lymph/vascular invasion sometimes observed •High grade tumor cells with numerous mitoses

Cutaneous Metastases v. Primary Adnexal Carcinoma
• Recent studies have shown that CK5/6 and p63 may help distinguish primary adnexal neoplasms (CK5/6+/p63+) from most metastatic carcinomas (CK5/6-/p63-)
• P63 especially helpful • D2-40 not been especially helpful in my lab

Cutaneous Metastases v. Primary Adnexal Carcinoma
• Impossible to reliably distinguish primary or metastatic eccrine/apocrine tumors from cutaneous metastases of breast carcinomas, especially apocrine or mucinous types
• Immunohistochemical Staining of Breast v. Metastases •ER (estrogen receptor) •PR (progesterone receptor) •GCDFP-15 (gross cystic disease fluid protein) •CEA •Her-2-neu
• None of these may reliably separate primary sweat duct tumors from breast metastases

Cutaneous Metastases v. Primary Adnexal Carcinoma
• Aberrant staining of metastases •Technical
•Antibody •Technique
•Therapeutic effect – chemo and/or radiation/immune modulators •Tumor metastases may have different immuno phenotypes than the primary •Tumors don’t always read the books •Another tumor/primary is responsible for the aberrant staining

Cutaneous Metastases v. Primary Adnexal Carcinoma
• Take Home •H&E considerations and clinical information most important for diagnostic purposes •Immunohistochemistry stains are useful ancillary studies, especially cytokeratin 5/6 and p63 but be careful as these may lead you astray •Be sure to eliminate the possibility of a basal cell carcinoma demonstrating unusual growth patterns •Always think of the possibility of a primary adnexal CA in the appropriate clinical and histologic context •Occasional inability to differentiate a primary adnexal CA from a visceral metastasis
