Myxofibrosarcoma or myxoid malignant fibrous histiocytoma is one of the most common fibroblastic sarcomas in older patients. It is characterized by a tendency for predominantly subcutaneous, multinodular, diffusely infiltrative growth, which may extend to the overlying dermis and present as a cutaneous lesion. Histologically, it comprises a spectrum ranging from hypocellular low-grade myxoid to high-grade pleomorphic sarcoma. Because the dermal presentation usually appears relatively banal, accurate diagnosis is sometimes challenging. In this report, we present two cases of myxofibrosarcoma with dermal involvement.
