[Abdominal cystic lymphangioma: a case report].

Intra-abdominal cystic lymphangioma is a rare dysembryogenetic tumour. Although laparoscopic treatment may be feasible and has been reported in the literature, the extension of the mass to the retroperitoneum can make a minimally invasive surgical approach difficult or impossible. We describe the case of a patient with lymphangioma with retroperitoneal extension who underwent successful surgical therapy.
