Abstract
- A Bednar tumor is a rare pigmented subtype of dermatofibrosarcoma protuberans (DFSP). The clinical and histopathological findings of Bednar tumors are identical to DFSP, except for the presence of melanin-containing cells within the lesion. We present a case of a Bednar tumor on the left anterior chest of a 58-years-old woman. It was presented as an asymptomatic, firm, hyperpigmented 1.8x2.7cm sized nodule with surrounding erythematous patch which had been present for over 35 years. The tumor was treated by wide local excision of the lesion. There has been no evidence of recurrence during a 1 year follow-up period.
