title: [Retroperitoneal cystic lymphangioma: about 5 cases and review of the literature].
abstract: Cystic lymphangioma is a rare, benign malformation of the lymphatic vessels which may be observed on various locations. Retroperitoneal location is less common than mesenteric location. Cystic lymphangioma has a polymorphic clinical presentation. Diagnosis is based on imaging but requires histological confirmation. Surgery is the treatment of choice. The aim of our study is to analyze the clinical manifestations, complications, diagnostic and therapeutic aspects of this tumor. We report a case series of 5 patients with retroperitoneal cystic lymphangioma (4 women and 1 man) operated in our department between the years 2004 and 2014. Their medical records were reviewed retrospectively. Follow-up was based on clinical examination and abdominal CT scan. The average age was 45 years. The mean follow-up was 32.6 months. The most common symptoms indicative of retroperitoneal cystic lymphangioma were pains and/or an abdominal mass. Abdominal CT scan was the most useful diagnostic test. Total resection was immediately achieved in 4 patients and it was deferred for up to 5 years in one patient. He underwent annual ultrasound monitoring. One patient underwent nephrectomy. No recurrence or complications were noted in 5 patients. Retroperitoneal cystic lymphangioma is a rare condition. Its therapeutic management is based on complete resection in patients with symptomatic lesions or complications, in order to limit the risk of recurrence. Complete resection may be deferred in asymptomatic patients.
