Abdominal Cystic Lymphangioma Eight Years After Inguinal Herniotomy Intra-abdominal cystic lymphangioma, accounting for approximately 5% of all cystic lymphangiomas, are mainly congenital in origin. Hence, they are usually diagnosed during the first 2 decades of life – in contrast to mesenteric cysts. In adults, cystic lymphangiomas resulting from malformed and inadequately draining lymphatic channels are rare. We report the case of a 73-years-old male patient in whom a cystic, fluid-filled right epigastric tumour of approximately 10 cm in diameter was diagnosed on routine examination. The past medical history included a bilateral inguinal herniotomy 8 years ago. During the recent operation the cystic tumour was resected from the mesentery of the right colonic flexure without complications. Histopathological examination revealed a cystic lymphangioma with small calcified foci. The facts that the lymphangioma was diagnosed for the first time at the age of 73 years and that it had not been detected at the time of the herniotomy 8 years previously, leave a link between this cystic lymphangioma and the herniotomy subject to discussion.
