Introduction/Context/Diagnosis

Objective: We report a case of a rare lesion in the maxillofacial area, a lingual osseous choristoma, in a 24-year-old female on the posterior dorsum of the tongue.

Abstract: A healthy 24-year-old female was referred for evaluation of a nodule involving the posterior third of her tongue, at the midline. The lesion had been present for years. The differential diagnosis included a lingual thyroid, granular cell tumor, osseous choristoma, Schwannoma, and adenoid cystic carcinoma.

Methods/Treatment Plan

An excisional biopsy was performed and microscopic examination of the specimen revealed the presence of well-defined nodule of mature lamellar bone.

Results/Outcome

The lesion was diagnosed as an osseous choristoma, being a mass of normal bone found in a place where such tissue is abnormal. In this report, we will seek to move through the diagnostic approach to eliminate each of the lesions laid out in the differential diagnosis while analyzing the case itself and the nature of the biopsy. We present the case of this rare and benign lesion of the tongue to contribute to the few similar reports of such a lesion in literature.

Significance/Conclusions

The diagnostic challenges that come with any lesion of this nature and location are plentiful. We seek to shed light on this rare case and to display a diagnostic approach to arriving at the final conclusion.
