Hemangioendothelioma  

Haemangioendothelioma is an uncommon vascular tumour with biological behaviour intermediate between haemangioma and angiosarcoma that can affect any site in the oral cavity. It often appears as a painless erythematous or purplish nodule, and can erode into underlying bone. Wide local excision with close follow-up is the treatment of choice because of the unpredictable biological behaviour and recurrent potential.
