The presence of multiple dermatofibromas is rare and is defined as more than 15 lesions. Multiple clustered dermatofibroma (MCDF) is a distinct entity with only 12 reported cases in the literature. MCDF occurs in healthy individuals of both sexes in the first to third decades on the lower half of the body and portends an excellent prognosis. On histology, MCDF is consistent with benign dermatofibromas. We report a 31-year-old healthy Hispanic woman with a 14-year history of slowly progressive MCDF located on her right hip initially misdiagnosed as dermatofibrosarcoma protuberans. We believe this case represents the 13th report of MCDF in the literature and the second from North America.
