MALE INTRACYSTIC CARCINOMA OF THE BREAST WITH LYMPHATIC METASTASIS-REPORT OF A CASE-

Abstract

We experienced a case of male intracystic carcinoma of the breast with lymphatic metastasis. A 70-year-old man was seen at the department because of a right breast mass. A solid tumor in the cyst measured 48×45×42mm in diameter was revealed on ultrasonography. After making a diagnosis of intracystic carcinoma by a mammogram, ultrasonography and an excisional biopsy, a modified mastectomy with lymph node resection was perfomed. Histologically, it was diagnosed as papillally intracystic carcinoma with metastasis to the axillary lymph node.
Intracystic carcinoma of the breast in male is a rare disease, and 13 cases have been reported in the Japanese litarature. So far no metastases to the axillary lymph nodes have been reported, and tumor excision without lymph node dissection has been the satisfactory treatment for male intracystic carcinomas. It may be necessary, however, to indicate lymph nodes dissection case by case.
