Cellular dermatofibroma: Benign or malign?

Different clinical and histopathologic types of dermatofibromas (benign fibrous histiocytoma (FH)) have been defined. Cellular dermatofibroma accounts for approximately 5% of benign FH. In the relevant literature, there are reported cases of lung metastases and inguinal lymph node metastases. In this paper we present a 25-year-old women who presented to our outpatient clinic with 3x4 cm nodule mass in the distal tibia and received the histopathological diagnosis of cellular dermatofibroma after total excision. In the literature, cases of dermatofibroma metastasizing to the lung and inguinal lymph nodes have been reported. We present this rare case of cellular dermatofibroma to highlight its potential for distant metastasis.
