Arch Pathol Lab Med. 2001 Aug;125(8):1101-3. doi: 10.5858/2001-125-1101-MPAWAP.

Abstract

We report the case of a 78-year-old man who developed a breast mass 12 months after hormonal therapy for palliation of prostatic adenocarcinoma. On histologic and immunohistochemical examination, the breast tumor revealed a unique collision tumor composed of metastatic prostatic adenocarcinoma and solid papillary breast carcinoma.
