Cellular dermatofibroma: A case report and review of the literature

Dermatofibroma is the most typical cutaneous spindle cell tumor. Cellular dermatofibromas (also known as CDFs) are a rare type of dermatofibroma that have a propensity to recur. Rarely, they may metastasize and exhibit histologic similarities to an aggressive disease. Recurrence rates for CDF are known to range from 10% to 26%. The histopathology of the lesions in recurrent and non-recurrent instances did not differ significantly. A factor that appeared to be linked to a higher chance of recurrence was the size of the initial lesion and whether the margins were implicated initially.
