Myxoinflammatory fibroblastic sarcoma (MIFS) is a recently described, rare low-grade sarcoma. Generally located in the upper and lower extremities, MIFS clinically mimics a benign cystic mass and is composed of spindle-like or atypical cells and mixed inflanunatory infiltrates located in the fibroblastic myxoid stroma. Radiologic images and macroscopic appearance generally resemble a lobulated mass with irregular margins. We present a case of a tumoral mass with neoplastic cells at the center and a smooth surface with a previously undefined appearance. Myxoinflammatory fibroblastic sarcoma is significantly difficult to distinguish clinically from benign lesions and the surgeon should consider the possibility of malignancy in lesions located at the extremities.
