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 [1,2].

The treatment of these lesions is surgical excision without margin when they are single lesions. Other methods that have shown good results include carbon dioxide vaporization and laser treatment [4].

A 45-year-old man with no notable pathological history presented to our department with a left scrotal subcutaneous formation that had been progressively evolving for 1 year.The clinical examination found a subcutaneous nodule of cystic consistency measuring approximately 1 cm. It was not tender, the skin covering the cyst was normal. There was no evidence of pain, tenderness, pruritus, or other symptoms.A scrotal ultrasound was ordered.

Excision of the mass was performed under local anesthesia.Histological examination noted the presence of a cystic formation bordered by a double layer of secretory columnar cells with decapitation images.the peripheral cubic layer was made of myoepithelial cells. There were papillary projections within the cavity.The diagnosis of scrotal apocrine hidrocystoma was made.
