Recurrent noduloulcerative growth on the face

Sir, clear cell hidradenoma (CCH) is an uncommon, benign, slowly growing cutaneous tumor of the sweat glands. It is mostly seen in adults and is characterized clinically by solitary and firm intradermal nodule. Women are affected more often than men. Presence of malignant change is suggested clinically by a rapid growth and cutaneous ulceration and histologically by an increased number of mitotic figures, nuclear atypia and angiolymphatic or perineural invasion. We present a case of fifty year old female who had recurrent noduloulcerative hidradenoma even after complete excision over a span of three years.
