Pedunculated Eccrine Porocarcinoma / 대한피부과학회지

Eccrine porocarcinoma is a rare, malignant skin tumor that originates from the eccrine sweat gland. This disease affects elderly people, primarily. It is clinically present in varied forms and the location is not related to sweat-gland distribution, which occurs on the lower limb, trunk, and head. Herein, we report a rare case of pedunculated eccrine porocarcinoma, which had developed on the flank of a 79-year-old woman.
