Meigs' syndrome is defined by the presence of ascites and hydrothorax in association with "fibroma-like" benign ovarian tumors. Tumor extirpation resulted in a resorption of the ascites and a pleural effusion. A Krukenberg tumor resulting from stomach cancer would be highly suggested when stomach cancer, ovarian tumor, and ascites are found concomitantly. However, when a patient presents with ovarian tumor, stomach cancer, and repeated cytologic examination of the ascitic fluid renders negative results, stomach cancer associated with Meigs' syndrome should be considered in the differential diagnosis. We report a case of stomach cancer presenting with Meigs' syndrome in a 70-year-old woman who had been referred for control of intractable ascites. The patient was cured by radical subtotal gastrectomy and bilateral oophorectomy.
