Primary Leiomyosarcoma of the Male Breast.

We describe herein the third case of primary leiomyosarcoma of the breast in a 62-year-old man. Preoperative clinical examination and cytology findings indicated a leiomyosarcoma of the breast. A modified radical mastectomy was performed. Immunohistochemical analysis subsequently confirmed a diagnosis of leiomyosarcoma. After a follow-up period of 24 months, the patient is still in good health with no evidence of locoregional recurrence or distant metastasis.
