A case report of desmoplastic ameloblastoma

Abstract

Ameloblastomas are the most common benign neoplasm of odontogenic nature. Desmoplastic ameloblastoma (DA) was included in the World Health Organization Classification of Head and Neck Tumors (WHO-2005) as a variant of ameloblastoma with specific clinical, image, and histological features. This case report focuses on a DA which occurred in the mandible of a 25 year-old man. The main signals and symptoms included painless swelling with buccal expansion and tooth displacement. Panoramic and periapical radiographs and cone-bean computed tomography demonstrated an image mimicking a benign fibro-osseous lesion. The lower border of the mandible was not involved, but tooth displacement could be observed. An incisional biopsy was performed, and the DA was diagnosed. A marginal resection, maintaining the lower border of the mandible, was performed on teeth 46 to 31. The post-operative period was uneventful. The patient is undergoing routine follow-up and is currently free of disease.
