Eruptive dermatofibromas in a pregnant woman

Abstract

Dermatofibromas (DF) or benign fibrous histiocytofibromas represent one of the most common skin tumors. It is a soft tissue and bone tumor composed of fibroblastic and histiocytic components without nuclear pleomorphism or histological anaplasia. The eruptive form and the multiple form are 2 subunits of DF that are rare, their pathophysiology and the factors inducing its proliferation remain poorly understood. Autoimmune or neoplastic diseases are incriminated, but hormonal or toxic factors have never been elucidated. the pigmented network and the central whitish appearance is the most prominent dermoscopic pattern in the literature.
