Odontogenic Myxoma of Mandible Appeared as an Ameloblastoma on CT Imaging.

ABSTRACT

Odontogenic myxoma is a rare benign tumor of ectomesenchymal origin, which can arise from dental papilla, follicle or periodontal ligament. Most commonly it arises from mandible followed by maxilla. We report a case of odontogenic myxoma in a 23 years old female who came with complaint of painless swelling in left mandible. CT scan revealed an expansile radiolucent lesion involving the left mandible body with cortical thinning and mild destruction at few places. Biopsy was done which was suggestive of odontogenic myxoma. Surgery was done and odontogenic myxoma was proved on the biopsy.
