Introduction: Lymphangiomas are rare benign mesodermal tumors of the lymphatic system. The intra-abdominal and the retroperitoneal location of these lesions is one of the most infrequent sites of appearance. Usually comes out in infancy more than in adulthood. Most patients experience chronic symptoms and magnetic resonance imaging is the best radiologic study for their diagnosis. Excision is the treatment of choice and laparoscopic resection is a very good option but there are very few publications reported in literature. The aim of this presentation is to confirm the benefits of the laparoscopic approach for this tumour localization. Case presentation: A 49-year-old woman with no relevant history was admitted to our institution with left lumbar pain of six months of recurrent history. A 60 mm in diameter retroperitoneal cystic tumour was diagnosed by abdominal computed tomography and magnetic resonance imaging. No percutaneous guided-biopsy was performed. The tumour was successfully resected by laparoscopic approach. No postoperative complications occurred and was discharged at the second day. The patient's pain disappeared. Histopathological examination revealed a benign retroperitoneal lymphangioma. Conclusions: The laparoscopic approach is a safe and effective alternative for treatment of retroperitoneal lymphangioma. As in other laparoscopic procedures, the patient have all the advantages of the mini-invasive surgery.
