Extraordinary Case Report

Abstract: Myxoinflammatory fibroblastic sarcoma (MIFS) is a rare low-grade tumor of modified fibroblasts, with tendency to local recurrence. This unusual entity typically presents as a slow-growing painless mass in the distal extremities of middle-aged subjects. A 48-year-old woman presented to our clinic with a painless subcutaneous mass in the right temporal region. Excisional biopsy made the rare diagnosis of MIFS. Histologic examination showed the unique features that characterize this lesion: a myxoid component with a superimposed inflammatory infiltrate and the presence of distinctive, large, and bizarre Reed-Stemberg–like cells. A second wide tumor bed resection was performed, achieving clear margins. No adjuvant therapy was administered, and the patient is free of disease at 18 months postoperatively. To the best of our knowledge, this is the first reported case of MIFS presenting in the face. This adds another possibility for differential diagnoses of soft tissue tumors of the face.
