Multiple Eruptive Eccrine Poromas Associated with Chemotherapy and Autologous Bone Marrow Transplantation.

ABSTRACT

Eccrine poroma is a benign adnexal tumor that originates from the uppermost portion of the intraepidermal eccrine duct. It usually presents as a solitary tumor. Histopathology shows a monomorphic proliferation of cuboidal cells, which radially extend from the basal layer to the dermis. Here, we present a rare multilesional eruption of eccrine poroma after chemotherapy and bone marrow stem cell transplantation for acute promyelocytic leukemia along with a description of clinical, pathological, and dermoscopic findings.
