A Case of Apocrine Carcinoma on the Pubis / 대한피부과학회지

ABSTRACT

Apocrine carcinoma is a rare malignant epithelial tumor of apocrine sweat glands. It manifests as a painless, slow-growing, firm or cystic red nodule with focal ulcerations. These tumors are capable of hematogenous dissemination to visceral organs and lymphatic spread. Their occurrence has been reported mainly in the axilla and breast area. We present a case of apocrine carcinoma arising from the pubis, where it rarely occurs. An 83-year-old man displayed a 3.5x3.0 cm-sized irregular-shaped mass with a crust. Histopathologic examination revealed a complex glandular appearance of cribriform and cord-like pattern tumor nests throughout the dermis. The tumor was positive in immunohistochemical staining for EMA, PAS diastase, and GCDFP-15.
