Apocrine hidradenoma is a benign adnexal neoplasm. It has no specific site predilection, and usually affects middle-aged people. The same as other tumors of the sweat glands, there is a pigmented variety. We present the case of a 92-year-old male who consulted his physician for a slow-growing asymptomatic lesion in the right groin which had been developing for 2 years. After the histopathological study, the diagnosis was established as pigmented apocrine hidradenoma.
