Recurrence of a dermatofibrosarcoma protuberans? Rare case.

Dermatofibrosarcoma protuberans (DFS) is a mesenchymal-origin skin tumor with intermediate malignancy. Though rare, it's not exceptional, comprising about 0.1% of malignant skin tumors. The authors discuss clinical, radiological, histopathological studies, and various therapeutic modalities for this tumor. Our 82-year-old patient presented with a 3 cm swelling on the right arm, initially undergoing biopsy followed by surgical excision of the mass. Adjuvant treatment with radiotherapy or chemotherapy is unnecessary unless recurrence or malignant transformation occurs. Histological analysis is crucial for diagnosis. The preferred treatment method is wide surgical excision. Prognosis primarily depends on malignancy, especially at the local level, with a high risk of recurrence. It's rare for a distinctly malignant sarcomatous transformation with metastasis to occur.
