Dermatofibrosarcoma protuberans is a locally aggressive skin tumor. In addition to the conventional type, several morphologic variants have been described and Bednar tumor is one of them. We report herein a peculiar case of pigmented dermatofibrosarcoma protuberans (Bednar tumor), a distinctive pattern. The tumor occurred in a 23-year-old woman who presented with a lesion on her left suprascapular area of 10 years of history.
