Eccrine porocarcinoma is a malignant tumor of eccrine sweat glands. It
is a very rare, slow growing tumor and clinically resembles other ski
n cancers. We report a case and review its clinical and pathological f
eatures. These tumors have a propensity for local recurrence, and wide
excision with negative margins is recommended. (C) 1997 by the Americ
