Lymphangioma is a benign infiltrative malformation of the lymphatic channels. Cystic lymphangioma or cystic hygroma is a subtype of lymphangioma which exhibits large macroscopic cystic space histologically. The cause of cystic hygroma is believed to be developmental defect or primary Multilocular cystic malformation of dilated lymphatic channels. ⋯ Various treatment modalities have been tried. Surgery has been the main form of treatment, but total removal is not possible in all cases because of the extent of the lesion, which sometimes involves vital structures. We report a case of cystic hygroma in a young male patient.
