Abstract

Clear cell hidradenocarcinoma is a malignant tumor of the sweat glands that represents less than 0.001% of the skin appendages malignant tumors. The original description is attributed to Keasbey and Headley in 1954. Its origin can be primary or it can be developed on a pre-existing benign neoplasm. This neoplasm mainly affects male patients with an average age of 50. The most frequent topographic location is on the head followed by the neck and extremities In most of the cases, it is presented as a solitary tumor of a variable size of 1 to 5 cm, not well demarcated, either ulcerated or not. Typically, asymptomatic, slow growing and developing metastases approximately 60% within the first 2 years, the 5-year survival rate, is less than 30%. The diagnosis is confirmed by a histopathologic study. The treatment of choice is a surgical procedure with wide margins. Other alternatives are chemotherapy and radiotherapy.
