Apocrine Hidrocystoma on the Penis: Report of a Case and Review of the Previous Cases

초록

Apocrine hidrocystoma, also called apocrine cystadenoma, is a benign cystic tumor-like lesion that arises from the proliferation of apocrine glands. Clinically, it usually occurs singly as a unilocular or multilocular, dome-shaped translucent cyst. Histologically, it appears as unilocular or multilocular cysts composed of an inner layer of single or double layer of secretory columnar epithelium with decapitation secretion lying above an outer myoepithelial cell layer. Apocrine hidrocystomas mostly occur within the head and neck region and involvement of genitalia is extremely rare. This paper emphasizes the importance of considering the differential diagnosis of a genital cystic lesion. Herein, we report a case of apocrine hidrocystoma occurring in the penis and compare the clinicopathological characteristics of apocrine hidrocystoma in genitalia with the previous cases.
