Case Discussion

Torus mandibularius is a bilateral bony growth from the buccal mandible anteriorly near the premolars above the mylohyoid muscle. Etiology is unclear and they are usually asymptomatic (apart form a hard lump). Occasionally they can cause ulceration to the overlying mucosa as in this case.

Differential diagnosis: multiple buccal exostosis 1
