[Cystic lymphangioma of the abdominal wall in childhood: case report].

Intra-abdominal lymphangiomas are rare benign tumours that can cause various symptoms, mainly during childhood. They are diagnosed by ultrasonography, CT scanning or at laparotomy; ultrasonographic examination often shows a voluminous tumoral cystic formation with septa. The location of the cyst may be determined either by ultrasonography alone or by CT scanning. The definitive histological diagnosis is confirmed by immunohistochemical staining techniques. Rarely intra-abdominal lymphangiomas can occur in the abdominal wall. Complete resection is the treatment of choice. The case of a 2-year-old-boy with a large lymphangioma involving the lower half of the abdominal wall is reported. The patient underwent the complete removal of lymphangioma with good cosmetic result.
