Pseudomyxoma Peritonei in a Patient with History of Breast Cancer.

Pseudomyxoma peritonei is a very rare condition, and even rarer in patients with history of cancer. A 70-year old woman with a history of breast cancer was admitted with abdominal pain and distention. Abdominal computed tomography revealed ascites collection, diffuse engorgement and infiltration of the mesenteric vessel, suggesting peritonitis or peritoneal carcinomatosis.
