Adenoid cystic carcinoma of buccal mucosa with extensive hyalinization: A unique case report

Adenoid cystic carcinoma (ACC) is a malignant tumor of salivary glands, 50% of which affect the minor salivary glands. ACC is known for its prolonged clinical course, multiple recurrence rates, and delayed onset of distant metastasis. The tumor usually shows one of the three histopathological variants which are cribriform, tubular, or solid pattern. Here we present a case of ACC affecting rightbuccal mucosa which histopathologically showed cribriform pattern with abundant hyalinization. Surgical excision was the only treatment done without any additional modalities and patient is free of disease since 10 years.
