title: Unusual presentation of cancer.
abstract: The large bowel is the most frequent primary site for metastases in inguinal hernial sacs. We report four cases, two due to carcinoid of unknown primary, and one each due to adenocarcinoma of colon, stomach and pancreas. We recommend that all hernial sacs, particularly in the elderly, be examined microscopically.
