Adenoid Cystic Cancer
Adenoid cystic carcinoma (ACC) is a rare malignancy arising from the secretory glands, most commonly seen involving the salivary glands. It accounts for approximately 1% of all malignancies of the head and neck region. However, it is the most common tumor of the minor salivary glands and the second most common tumor of the major salivary glands. Overall, it accounts for 10% of all salivary gland tumors. The tumor is typically slow-growing compared to other carcinomas and has a tendency for perineural invasion as well as hematogenous spread to distant organs and is most commonly seen in the elderly. Due to its rarity, limited data is available regarding the predisposing risk factors and the management of patients with advanced disease.
