Abstract

Malignant clear cell hidradenomas are rare tumors originating from the eccrine sweat gland. Usually, they are malignant from their inception, but some develop from benign nodular hidradenomas. Although there is insufficient evidence in the literature, the recurrence rate may be estimated at about 50%, and the metastasis rate is about 60%, including regional nodes, bone, viscera, and the skin. We report a case of malignant clear cell hidradenoma in a 63-year-old woman, who had a 3-year history of asymptomatic pea sized hard solitary nodules on the right forearm. Despite repetitive surgical excisions, the lesions were recurred 5 times. To our best knowledge this is the first case of malignant clear cell hidradenoma in the Korean dermatologic literature.
