A 68-year-old woman visited her local clinic with refractory watery stools and weight loss, and a giant pelvic tumor was identified. Since an ovarian tumor was suspected, she was referred to our hospital. Blood biochemistry revealed marked hypoalbuminemia, and colonoscopy revealed the presence of cancer in the ascending colon. These findings led to a preoperative diagnosis of either concomitant ovarian and colon cancers or ovarian cancer with tumor infiltration into the colon, and surgery was performed. The tumor was identified in the ascending colon, and had caused a significantly tense intestinal tract. Diameters of the ovaries and fallopian tubes on both sides were almost within normal ranges. A right hemicolectomy and bilateral salpingo-oophorectomy were performed, and the histological type of the tumor was well-differentiated mucinous carcinoma. These findings suggested that the patient had colon cancer with protein-losing gastroenteropathy. Protein-losing gastroenteropathy caused by colon cancer is rare, with few reports to date. We describe our findings and discuss the literature.
