Adenoid cystic carcinoma is a rare type of cancer that can exist in many different body sites. This tumor most often occurs in the salivary glands, but it can also be found in many anatomic sites, including the breast,[1][2] lacrimal gland, lung, brain, Bartholin gland, trachea, and the paranasal sinuses.

It is the third-most common malignant salivary gland tumor overall (after mucoepidermoid carcinoma and polymorphous adenocarcinoma). It represents 28% of malignant submandibular gland tumors, making it the single most common malignant salivary gland tumor in this region. Patients may survive for years with metastases because this tumor is generally well-differentiated and slow growing. In a 1999 study[3] of a cohort of 160 ACC patients, disease-specific survival was 89% at 5 years, but only 40% at 15 years,[citation needed] reflecting deaths from late-occurring metastatic disease.
