Bilateral breast metastasis from mucinous adenocarcinoma of the rectum: a case report and review of the literature

Abstract

Metastatic breast carcinoma is rarely seen in clinical practice. It has been reported that lymphoma-leukemia, melanoma and sarcomas can metastasize to the breast. Bilateral metastases to the breast are rare and commonly have been seen to originate from ovarian carcinoma. Adenocarcinoma of rectum metastasizing to breast is an extremely rare clinico-pathological situation. We report a 28-year-old female who presented with bilateral breast metastasis 9 months after abdomino-perineal resection and total meso-rectal excision for a locally advanced mucinous adenocarcinoma of the rectum. A few case reports of a mucinous adenocarcinoma of rectum presenting with bilateral breast metastasis have been seen in the world literature and we hereby report this case who till now is the youngest patient reported.
