Case reports of oral choristomas and a review of the literature

Choristomas are proliferative growths that occur when normal tissue develops in abnormal locations and may resemble tumors. Oral choristomas commonly present as slow-growing, indolent, and firm masses. The diagnosis primarily relies on histopathologic examination. Given their tumor-like growth and developmental pathogenesis, it is critical to differentiate them from neoplasms. In this article, we present two clinical cases of oral choristomas, a cartilaginous choristoma, and an osseous choristoma of the tongue. We also offer a brief review of the literature discussing clinical presentation, microscopic features, and therapeutic options. (c) 2024 Elsevier Masson SAS. All rights reserved.
