ABSTRACT
Collision tumors are those which are of two distinct histological features and tend to occur at same anatomical site. One such rare collision tumor is a hemangiomatous ameloblastoma. This tumor is unique as two neoplasms one that of vascular origin and another of odontogenic origin tend to occur at one site. But due to paucity of reported cases the exact mechanism of formation is not known. Therefore, we report a case of such rare entity. A 32 year female patient reported to the outpatient department of our institute. She presented with a massive growth present in anterior maxilla region present since four months. She underwent an excisional biopsy which came out to be reported as Hemangiomatous Ameloblastoma. The healing was uneventful. Hemangiomatous Ameloblastoma is considered as a variant of solid multicystic ameloblastoma. On a thorough literature search we found that till date only eleven cases have been reported. Due to this scarcity of reported cases, the exact pathogenesis is less understood. Moreover the clinical behaviour is also less studied which makes it important for this neoplasm to be considered as a separate entity.
Key words: Hemangiomatous ameloblastoma, Collision tumor, Follicular Ameloblastoma, Cavernous Hemangioma.
