[An apocrine hidrocystoma of the scrotum. A case report].

A benign neoplastic lesion of the skin originating from cystic proliferation of apocrine secretory glands is defined as an apocrine hidrocystoma or cystadenoma. The tumor usually occurs in adults as a solitary cystic lesion; it is commonly found on the periorbital region, neck, upper torso and limbs. The case presented is unusual because of the age of the patient--cystadenoma is very rare in childhood--and the localization of the lesion. From a literature review and to the best of our knowledge, a scrotal cyst has never been previously described. Surgical excision is the treatment of choice since the lesion does not tend to recur.
