Primary cutaneous adenoid cystic carcinoma of shin

Abstract

Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare variant of adenoid cystic carcinoma (ACC) which originates from the skin adnexa, most probably eccrine and apocrine glands. This tumor has a head and neck predilection and also occurs in the chest, abdomen, back, and perineum. We hereby present a 63-year-old man with PCACC located on the shin. No previous similar case has been reported in English literature; therefore, we decided to share our experience about its clinical behavior, histopathologic findings, and management. © 2014 Iranian Society of Dermatology.
