Hemangiomatous ameloblastoma: Case report with a brief review

Abstract

Ameloblastoma is a benign epithelial odontogenic tumor with many histological variants. Hemangiomatous ameloblastoma (HA) is a very rare variant which shows unique histopathological features varying from conventional ameloblastoma. We present a case of a 35-year-old female patient with a swelling over right lower back region of jaw, showing mixed radiolucent-opacity. Incisional biopsy showed microscopic features of desmoplastic ameloblastoma showing extensive desmoplasia and compressed odontogenic epithelial islands. Excisional biopsy revealed ameloblastomatous areas with extensive vascular component microscopically. Based on these findings, a diagnosis of HA was made.

Papilliferous Keratoameloblastoma

“…5 Trauma or stimulation of vessels closely associated with the dental follicle has been suggested as the reason for the highly vascular transition of the stroma in AM. 27 While the tumour cells in a majority of the cases had a benign morphology, a high mitotic rate of 3 mitoses/high power field was reported by Collini et al 10 Recurrences occurred after 39 and 58 months in their case. 10 The patient ultimately succumbed to non-Hodgkin lymphoma (NHL) after six years.…”
