Tuberculous granuloma and adenoid cystic carcinoma presenting as a single buccal space mass.

We report an unusual case of a 58-year-old man with a "collision lesion" of the buccal space. Initially diagnosed as tuberculoma, the patient showed only partial response to an extensive course of antibiotics, prompting more vigorous investigation. This revealed the presence of a concomitant malignancy, specifically adenoid cystic carcinoma. Definitive treatment was then achieved by surgical resection and flap reconstruction with postoperative radiation therapy.
