title: [Breast metastases from extramammary malignancies in men].
abstract: Metastases to the breast from extramammary carcinomas are rare. Carcinoma of the male breast is generally regarded as primary in origin and uncommon, accounting for less than 0.42% of all malignancies in men. Tow men who presented with breast malignancies in the course of their prostatic carcinoma are described. One was metastasis to the breast from prostatic cancer, the other from pancreatic cancer. The prostatic origin of these carcinomas, was confirmed by histological findings and immunocytochemical demonstration of prostatic acid phosphatase with the avidin-biotin-complex method.
