Dermatofibroma atrófico

Amanda Nascimento C. de Macedo Mota Violeta Duarte Tortelly Daniel Lago Obadia Roberto Souto da Silva About the authors

Dermatofibroma is a benign fibrohistiocytic tumor, common and easily diagnosed when classical clinicopathologic features are present. The atrophic variant of dermatofibroma is of uncertain origin. This lesion is characterized clinically by a flat or atrophic and depressible surface. Histopathological features show reduction of the thickness of the dermis and elastic fibers. We report a typical case of this uncommon and probably underdiagnosed variant.
