Breast Lump: An Uncommon Metastasis of Prostate Cancer

Abstract

Prostate carcinoma is the second most common cancer in men. Prostatic adenocarcinoma can metastasize to anywhere in the body. It is seen more commonly to lymph node, bone, lung, liver, breast, eyes, kidney, muscle, pancreas, spleen and rarely to adrenal or breast. Prostate carcinoma in form of breast metastasis is extremely rare. Here we discuss a case of 73 year old male k/c/o carcinoma prostate on hormonal treatment and recently diagnosed to have castrate resistant prostatic adenocarcinoma (mCRPC); who developed a large breast lump. Histopathology revealed metastatic deposit from prostatic adenocarcinoma which was confirmed by IHC. Patient responded to docetaxel chemotherapy and is on regular follow-up.
