This study explores the clinical manifestation and unusual behavior of intraoral hemangioma. ABSTRACT: Hemangioma is a tumor that occurs due to the proliferation of endothelial cells in 4%-5% of infants and affects the head and neck region in almost 70% of cases. The tumor in the mouth can appear as a soft, smooth, or lobulated mass with or without a base and varying in size from a few millimeters to a few centimeters.
