title: [Retroperitoneal cystic lymphangioma in childhood].
abstract: Lymphangiomas are very common neoplasms in infancy. However, a retroperitoneal location is seldom observed. We present the case of a male with a history of chronic recurrent pain over a period of several years. An X-ray showed a calcic density in the left upper abdominal quadrant; the histological study revealed it to be a mixoid cystic lymphangioma. Clinical presentation varies greatly from an asymptomatic mass to serious complications. In order to correctly diagnose of these neoplasms it is essential to carry on ultra sound and CT examination although a simple abdominal X-ray may show calcifications as the one presented here. Treatment is always surgical and a complete extirpation should be performed, unless vital structures were are involved. Treatment with laser, fibrin and sclerotherapy have also been used.
  
  
  CONCLUSIONS
  In spite of being benign neoplasms we believe they should be removed to confirm diagnosis and avoid possible complications.
