Poroma

Poromas are benign tumors most commonly arising in the palms and soles as red-pink papules or nodules. Poromas generally occur in middle-aged adults with an equal predilection for men and women. Several conditions can be associated with the development of multiple lesions including radiation therapy, chemotherapy, pregnancy and post-transplant. Histologically, they are nodular, well circumscribed and feature sheets and trabeculae of monomorphic cuboidal bland keratinocytes containing scattered duct-like structures.
