Giant cell variant of malignant fibrous histiocytoma of male breast: A rare case report.

Malignant fibrous histiocytoma (MFH) is the most common form of soft tissue sarcoma during middle and late adulthood in the deep connective tissue of the extremities, abdominal cavity, and retroperitoneum. However, primary breast sarcoma is a rare disease entity, comprising less than 1% of all breast malignancies. MFH of the male breast is very rare. We present a case of MFH of giant cell variant of the right breast in a 50-year-old male who presented with a painless lump. Following cytological investigation, simple mastectomy was performed. Immunohistochemical staining confirmed the diagnosis.
