Osseous Choristoma of the Gingiva: A Case Report with Insight to Etiological Theories

Choristomas of the oral cavity are rare nonneoplastic lesions that show histologically normal development of tissues at abnormal sites. These oral lesions can remain unnoticed or can progress to sizes that interfere with routine function accompanied with or without pain and other clinical symptoms. Osseous choristomas have been documented in the oral cavity, commonly in the tongue. The present report describes the case of osseous choristoma in the mandibular gingiva of a 61-year-old female patient and highlights the associated etiopathogenesis of choristoma.
