A case of Mucinous Carcinoma of the Male Breast with Unusual Ultrasonographic Findings Mimicking Phyllodes Tumor.

Abstract

Mucinous carcinoma of the male breast is a rare histological type of cancer. We describe a 35-year-old male with mucinous carcinoma of the right breast. His breast mass enlarged subacutely, and became painful over a period of 2 months. Ultrasonography demonstrated echoes of a large multilocular cystic lesion with partially heterogenic internal echoes suggesting a phyllodes tumor. A modified radical mastectomy was performed, and histopathologic examination revealed mucin-producing solid or cribriform atypical cells with fibrous granulation tissue and hemosiderin deposition. The patient recovered uneventfully, and is still free of recurrence 30 months after his operation. The prognosis for male breast cancer can be improved by early diagnosis and appropriate multidisciplinary therapy.
