Dermatofibrosarcoma protuberans (DFSP) is a rare spindle cell tumor, comprising less than 0.1% of all malignant neoplasms. The trunk is the most commonly affected area, followed by the extremities and the head and neck. Of the latter cases, involvement of the periorbital area has been infrequently reported. Surgery is the cornerstone of treatment but is associated with a high rate of recurrence if margins remain close or positive. This rate has been shown to be considerably decreased by the use of adjuvant radiotherapy. However, most reported cases utilize external beam radiation therapy (EBRT) in the treatment of DFSP, including those with primary periorbital locations. We report a case of a 40-year-old male, presenting with a small nodule on the right upper eyelid, diagnosed as DFSP with positive margins post-surgery and treated with adjuvant customized surface mould high-dose-rate (HDR) brachytherapy in a low-resource setting.
