Tumors found during hernia repair are rare. They may be intrasaccular (most commonly), saccular or extrasaccular, and they are usually primary. In this case report we present a case of metastatic adenocarcinoma (confirmed by biopsy) found inside the inguinal hernia sac. Following further investigation, primary tumor of the ileum and ileocecal junction was found. An elderly male presented with a history of bilateral inguinal swelling for a year, that had been asymptomatic initially, but had increased in size and was painful following prolonged activity. During laparoscopic hernioplasty a right sided inguinal hernia with nodules on peritoneum and omentum were observed. After taking a biopsy, repair of the hernia was performed. Carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 levels were raised. A computed tomography (CT) scan of the abdomen and chest showed a mass involving the distal ileum and the ileocecal junction, with lymphadenopathy, peritoneal carcinomatosis, as well as hepatic and lung metastasis. Surgery was not possible in this patient. A possible relation of an inguinal hernia with an ileal neoplasm was found in this patient. An irreducible swelling not causing any problems can be suspicious, which should be properly investigated to get to an early diagnosis.
