A rare tumor of atypical scrotal location

Abstract

Apocrine hidrocystoma is a rare benign adnexal tumor considered a cystic proliferation of the apocrine glands, rather than simple retentive cysts of the apocrine sweat glands [3]. It occurs most often in adults on the neck and head and especially on the external canthus of the eye [1,2]. They vary in size from 3 to 15 millimeters and are most often pigmented, blue, blue-black, grayish, translucent or violet in color. Apocrine hidrocystomas located in other sites such as the shoulders, fingers, abdomen and genital region have been rarely described.Differential diagnoses of apocrine hidrocystomas of scrotal location include eccrine hidrocystomas, blue nevus, melanoma, median raphe cyst, milium grain, epidermoid or pilar cyst, and hemolymphangioma
