Adenoid basal cell carcinoma and its mimics

Abstract

Basal cell carcinoma (BCC) is the most common malignant tumor of skin. The most common site (80%) is head and neck. BCC exhibits a varied morphology such as adenoid, keratotic, sebaceous, basosquamous, apocrine, eccrine or fibroepithelial. Tumors with a similar histopathological picture are cutaneous adenoid cystic carcinoma and primary cutaneous cribriform apocrine carcinoma. Immunohistochemistry, along with clinical findings, acts as an adjunct in reaching an accurate diagnosis. Here, we present an interesting case of adenoid BCC in a 55-year-old man.
