IMMUNOHISTOCHEMISTRY OF ECCRINE POROCARCINOMA

Oncology Reports, 1994
The eccrine porocarcinoma is a rare adnexal tumor of human skin. It has been related to the acrosyringeum of the sweat gland. An immunohistochemical study on paraffin sections of eight porocarcinomas and a control group of 29 poromas was conducted to investigate the differentiation of porocarcinomas.

We describe the case of a 42-year-old African American man who presented in February 1998 with a lesion on the plantar surface of his right foot that was diagnosed as an
