A 41-year-old female suffered from epigastralgia and intermittent constipation for 10 months, and abdominal fullness and intermittent pain for 6 months, before seeking help. Double contrast barium study of the colon showed multiple indentations on the sigmoid, ascending, and proximal transverse portions with tethered adjacent mucosal outline as well as the presence of ascites compatible with peritoneal carcinomatosis. Mediolateral oblique mammogram showed a speculated mass with some intratumoral microcalcifications in the upper retroareolar portion of the right breast. Due to the persistent abdominal complaints, laparotomy was done. Breast lump biopsy was done simultaneously. On opening abdominal cavity, massive yellowish ascites was noted. Diffuse small nodules over omentum and mesentery retraction were found. Bilateral ovarian masses were also noted. Right oophorectomy and omentectomy were performed. Histologic findings and results of immunohistochemical stains were consistent with diagnosis of primary breast cancer with metastasis to ovary and omentum.
