[Lymphangioma]

The term lymphangioma applies to two types of vascular malformations with very different prognoses: cystic lymphangioma, a benign and easy to treat condition, and tissue lymphangioma, a deeply infiltrating lesion the course of which is sprinkled with complications which may be severe in some locations. Therapeutic sclerosis of cystic pouches with ethibloc gives excellent results and must be performed prior to any surgical treatment, but it is ineffective in tissue lymphangioma which requires a difficult and often maiming treatment. Both types of lymphangioma may coexist, each one following a different course.
