Bednar Tumor – a Case Report

Bednar tumor is a rare pigmented type of the dermatofibrosarcoma protuberans characterized histologically by the coexistence of two distinct cell populations, including spindle-shaped cells and melanin-containing dendritic cells. We report dermoscopic features of Bednar tumor observed in a 54-year-old female patient. The dermoscopy of Bednar tumor revealed a multicomponent pattern composed of a homogeneous blue-gray pigmentation with shiny white lines, structureless light-brown pigmented areas and a peripheral pigment network. The dermoscopic features observed in the present case are consistent with reported dermoscopic descriptions of Bednar tumor. Although dermoscopy may be suggestive of the diagnosis of Bednar tumor, pathohistological examination remains a gold standard for diagnosis.
