title: Epidermotropic eccrine porocarcinoma.
abstract: Three cases of epidermotropic eccrine porocarcinoma are summarized and compared with reported cases. All patients had a long-standing tumor on a lower extremity that rapidly metastasized to the skin and proximal lymph nodes. The histologic picture was consistent with an intraepidermal eccrine sweat gland carcinoma.
