[Lymphangioma of the spleen. Apropos of 2 cases].

On the basis of two observed cases and a review of the literature, the extreme rarity of cystic lymphangioma of the spleen is pointed out. The presumed pathogenesis of the condition is described as are its greater frequency among the young, the possibility of dangerous complications and its non-malignity. The superiority of non-invasive instrumental diagnosis (echotomography and CAT) over traditional techniques is reported. Finally splenectomy is identified as the therapy of choice.
