A Case of Eccrine Porocarcinoma / 대한피부과학회지

ABSTRACT

Eccrine porocarcinoma is a very rare, locally aggressive, potentially fatal tumor arising from the intraepidermal ductal portion of the eccrine sweat gland. It develops either spontaneously or from a long standing benign eccrine poroma. It usually affects older persons and is located most commonly on the lower extremities. It is a slow growing tumor and clinically resembles other skin cancers. We report a case of eccrine porocarcinoma in a 57-year-od man. In this case, the tumor was located on the volar aspect of the right thumb, showing verrucous-surfaced, crusted nodular appearance. There was no evidence of metastasis.
