Abstract
|
|
|
|
Eccrine poroma is a benign tumor, which is thought to originate from the epidermal eccrine sweat duct unit. It occurs primarily on the hairless acral surface. However, there have been some cases occurring in atypical area like scalp and face. In general, eccrine poroma lacks melanin pigment clinically and melanocytes on microscopic examination. However, in either black or yellow skin, melanin granules and melanocytes can occasionally be found dispersed within the tumor. We report a case of pigmented eccrine poroma occurring on the scalp. The lesion was located on an unusual occurring site as well as contained melanocyte and melanin.
