Large bowel obstruction due to colonic and omental metastasis as the first clinical sign of metastatic ductal carcinoma of the breast]

Distant spread from breast cancer is commonly found in bones, lungs, liver and central nervous system. Metastatic involvement of peritoneum, omentum or/and gastro-intestinal tract is unusual and unexpected. We present the case of a 48 year-old woman who presented with gastro-intestinal symptoms as signs of omental and colonic metastasis of an invasive ductal breast cancer, which was not diagnosed before her admission. Ileus was diagnosed and urgent surgery was performed. Histology revealed metastatic ductal breast carcinoma. Mastectomy and axillary lymphadenectomy were performed therefore. Reviewing the literature--to the best of our knowledge--such a case has never been published before.
