Salivary gland adenocarcinoma not otherwise specified (NOS) represents as an invasive tumefaction demonstrating glandular or ductal differentiation. Generally, tumefaction is devoid of morphological features characteristic of diverse subtypes of malignant salivary gland neoplasms. With a frequently aggressive biological course, salivary gland adenocarcinoma (NOS) comprehensively configures up to 10% of malignant salivary gland tumours. Salivary gland adenocarcinoma (NOS) is essentially a diagnosis of exclusion.

Salivary gland adenocarcinoma (NOS) may metastasize into cervical lymph node (~23%) whereas distant metastases occur within 37% tumours. 5 year disease specific survival emerges at ~57%.
