Completely Isolated Arteriovenous Hemangioma in the Tongue

Abstract

We report a rare case of a completely isolated hemangioma with the histological findings of an arteriovenous hemangioma which occurred in the tongue of a 42-year-old female. This lesion was completely encapsulated by fibrous connective tissue and had focally proliferated with extensive vascular development. The tumor showed a lobular arrangement of vessels of generally uniform wall thickness. Vessel walls were stained by EVG and were immunohistochemically stained with SMA. Mast cells reactive for toluidine blue staining were frequently identified in the stroma and in the surrounding vascular area.
