Angioma

 

a benign tumor consisting of blood or lymph vessels. There are two forms of angioma—simple angioma, which is a congenital flat growth on the skin or mucous membrane, forming the basis of so-called vascular birthmarks (of bluish-purple color), somewhat elevated above the skin and requiring no treatment; and cavernous angioma, a tumor found in subcutaneous tissue or inside internal organs, sometimes giving rise to serious hemorrhages. Surgical removal of the latter type of angioma is necessary in case of rapid growth or the presence of disfigurement.
