Lymphangioma

Lymphangioma is a congenital benign tumor of dilated/proliferating lymphatic vessels and connective tissue containing lymph/lymphocytes/blood. Types: capillary, cavernous, cystic. Children (also adults); slow-growing, rare spontaneous regression. Small asymptomatic lesions may be observed; simple type treated by electrodesiccation/cryo/laser; cystic/cavernous require surgery (radiation insensitive), cavernous often recur.

Common Symptoms
