ABSTRACT Minor salivary gland neoplasms of the buccal mucosa are relatively uncommon. Adenoid cystic carcinoma (ACC), a well-defined entity, occurs most of the times in the parotid, submandibular glands and palate, as far as the intraoral site is concerned. Adenoid cystic carcinoma tends to have an indolent, extended clinical course with wide local infiltration and late distant metastases. We are presenting a case of an adenoid cystic carcinoma of the buccal mucosa in a 65-year-old male patient. INTRODUCTION: Adenoid cystic carcinoma is a rare epithelial tumour, and comprises about 1% of all malignant tumours of the oral and maxillofacial region. It is a malignant tumour which may develop in the trachea, bronchus, lungs or mammary glands, in addition to the head and neck region.1 The clinical and pathological findings typical of this tumor include slow growth, perineural invasion, and potential local …show more content…
In a study by Vidya et al 2,280 cases of ACC in a total of 41 articles. Out of these cases 1,382 were reported in intraoral sites and 178 were specifically reported in the buccal mucosa. Based on the above findings, they concluded that among intraoral minor salivary gland ACCs, 12.9% occurred in the buccal mucosa. The overall percentage of buccal mucosal ACCs was 7.8%. According to the articles reviewed, 60.6% of all adenoid cystic carcinomas occur in an intraoral
