Intraluminal plexiform hemangioameloblastomatous proliferation in unicystic ameloblastoma: an unusual case report.

The authors report a case of unicystic ameloblastoma with intraluminal plexiform hemangiomatous proliferation in the right mandible of an 18-year-old Indian male who suffered from painful swelling for 2 months. A radiograph showed a well-circumscribed multilocular radiolucent lesion associated with the angle and ramus of the mandible. Microscopic examination revealed the cystic lesion lined with ameloblastic epithelium with intraluminal plexiform hemangioameloblastomatous proliferation. The possible pathogenic mechanism for hemangiomatous appearance of this case reflects the previous history of extraction. The prognosis is perhaps the same as expected for conventional unicystic ameloblastoma.
