Hemangiomatous Ameloblastoma: A Rare Variant

Abstract

Ameloblastoma is a true neoplasm of enamel organ type tissue. It is the most common odontogenic neoplasm with more frequency in the mandible. A 20 years old male patient presented with a swelling in the right side of the mandible of 10 months duration. Orthopantomograph revealed multilocular radiolucency extending from the region of 46 to the condyle. Incision biopsy revealed features of plexiform ameloblastoma. Numerous vascular spaces of varying size were seen throughout the stroma. Excision biopsy also revealed similar findings. Based on these findings, a diagnosis of hemangiomatous plexiform ameloblastoma was made. Hemangiomatous ameloblastoma (HA) is still a controversial entity, with some pathologists ruling it out as a separate lesion. This paper discusses the possibility that HA might be an aggressive variant of ameloblastoma and reviews relevant literature.

Hemangiomatous ameloblastoma: Case report with a brief review

“…HA can occur at any age but is most commonly seen in the third and fourth decades of life with mandibular posterior region as the most common site which accords with the present case which had occurred in a 35-year-old patient in the right mandibular region. Previous reports showed male preponderance,[ 3 4 11 12 13 14 15 ] but in this case was a female. In the present case, the radiographic appearance showed mixed radio-opaque– radiolucent lesion which is consistent with other cases reported by Kasangari et al .,[ 3 ] Harshavardhan et al .,[ 13 ] and Rajmohan et al .…”

“…[ 4 ] and Rajmohan et al . [ 15 ] have opined that history of tooth extraction might be the etiological factor for the development of the vascular component. The other cases reported in the literature did not make a mention of the probable etiological factor.…”
