Clinical Report: Concurrent Occurrence of Lingual Osseous Choristoma and TGDC

Background

Lingual osseous choristoma is an exceedingly rare benign lesion characterized by mature bone tissue in the tongue's soft tissue. Thyroglossal duct cysts (TGDCs) are common congenital neck lesions resulting from incomplete involution of the thyroglossal duct. Both entities share a common embryological pathway extending from the tongue base through the hyoid bone to the lower cervical region.

Data Highlights

Key Findings

• The patient presented with a firm, pedunculated lesion on the posterior tongue.
• Contrast-enhanced MRI revealed a cystic lesion suggestive of a suprahyoid TGDC.
• Histopathological examination confirmed the diagnosis of both lingual osseous choristoma and TGDC.
• The surgical approach included partial resection of the hyoid bone and en bloc removal of the thyroglossal duct tract.

Clinical Implications

Thorough imaging of the thyroglossal tract is recommended when encountering osseous lesions of the tongue base.

Conclusion

This case highlights the rare synchronous occurrence of lingual osseous choristoma and TGDC.
