Lymphangioma is a tumor which is composed of lymph vessels and spaces containing lymph. It consists of endothelial cells and supporting tissue elements of the lymphatic system which are involved in the neoplastic process. Grossly, the cysts are thin walled and multiloculated. Intra-abdominal omental origin lymphangiomas are quite rare and only 21 cases were reported in English literature by 1978. The most common location is the mesentery, followed by the omentum, mesocolon, and retroperitoneum. We report a case of huge cystic lymphangioma originating from the greater omentum in a 14-year-old male patient with brief review of literatures.
