title: [Eccrine porocarcinoma: report of four cases and literature review].
abstract: Eccrine porocarcinoma is an extremely rare skin tumor derived from the acrosyringium. Four cases of eccrine porocarcinoma are described, two males and two females, aged from 49 to 64 years. Tumors grew in an interval of one to 20 years. Lesions ranged from 1.2 x 2 cm to 4 x 5 cm and were on limbs or face. Two patients had basal cell carcinoma in a site different from the eccrine porocarcinoma. Two biopsies were described as eccrine poroma. Malignancy was observed in all cases after wide excision. Therefore, eccrine porocarcinoma should always be considered after a biopsy compatible with eccrine poroma.
