Mesenteric cystic lymphangioma in adult: a case series and review of the literature

Introduction Lymphangiomas are rare benign tumors. They are preferentially located in the head, neck, and axilla in children.[1] However, lymphangiomas in the peritoneal cavity are extremely rare, particularly in adults. In the abdomen, lymphangiomas occur most commonly in the mesentery, followed by the omentum, mesocolon, and retroperitoneum. The etiology is unclear, but they are considered primarily to congenital in origin. [2] Preoperative diagnosis is often difficult due to the frequent silent clinical course. Radiological investigations are a useful diagnostic tool, but definitive diagnosis is confirmed by histopathology after a complete surgical resection. [3] The report describes five cases of adult patients with mesenteric lymphangioma.
