A Case of Malignant Clear Cell Hidradenoma

ABSTRACT

Malignant clear cell hidradenoma is a rare eccrine gland malignancy characterized by a solitary nodule on the head, trunk or distal extremity. We report a case of malignant clear cell hidradenoma in the left sole of a 66 year old female patient. Despite wide resection, regional lymph node dissection and radiation therapy, wide spread regional invasion and multiple distant metastasis were developed. As the malignant clear cell hidradenoma is reported rarely in the world and not yet reported in Korea, we report its clinical process of the diagnosis and treatment to patient's death.
