A rare case report of malignant fibrous histiocytoma of male breast

Malignant fibrous histiocytoma (MFH) is an extremely rare tumor of the breast that arises from the connective tissue of glands. Its complex and various histological patterns, adds difficulty to the diagnosis. We report a case of MFH of left breast in a 70-year-old male who presented with gradually increasing painless mass over a period of 1–2 years. Fine-needle aspiration cytology revealed malignant spindle cell lesion and wide local excision was performed without axillary lymph node dissection. Histopathological examination along with immunohistochemistry confirmed the diagnosis of MFH of left breast. To the best of our knowledge, this is the 6^th case of MFH of left breast in an elderly male reported in the literature.
