This report describes an extremely rare adult case of an omphalomesenteric cyst resected by laparoscopicassisted surgery. A 29-years-old Japanese man was referred and admitted to Kyushu University Hospital because of an abdominal mass and an elevated serum CEA (carcinoembryonic antigen) level (21.3 ng/mL) in August 2001. Abdominal CT and US demonstrated a cystic mass with septum and calcification. Laparoscopy showed a large mass to be attached to his abdominal wall, measuring 110 mm x 70 mm x 50 mm and filled with mucus. The mass was resected by laparoscopicassisted surgery. The histological findings of its wall showed fibromuscular tissue, adipose tissue, calcification,and an intestinal structure. It was finally diagnosed to be an omphalomesenteric cyst.
