An unusual swelling in the submandibular region: A case report

Abstract

Adenoid cystic carcinoma (ACC) is a slow-growing tumor of the salivary gland with high malignant potential, most commonly involving the minor salivary glands of the head and neck region. It is known for its long clinical course, indolent growth, local recurrence, and late distant metastasis. We report an unusual case of ACC in an adult male patient which remained undiagnosed for more than 15 years.
