(Background: The salivary glands have an important role in the functions of digestion by making lubrication fluid, respiration, speech, and overall homeostasis, and they also contain antibodies. Generally, the salivary gland tumors might be categorized into non inflammatory, inflammatory, and neoplastic swellings such as calculi, benign tumors like Warthin tumor, oncocytoma, pleomorphic adenoma, malignant tumors involving undifferentiated carcinoma, adenoid cystic carcinoma, and adenocarcinoma. Methodology: This epidemiological study is carried out at the Department of histopathology, Zakho general hospital, thirty salivary glands cases are involved in this work in a period of 15-years. Results: There are 30 patients with major salivary gland tumors, while 26 patients (86.666) had parotid and 4 patients (13.333) had sub-mandibular major salivary gland tumors. In the presented work, 26 (86.666) cases from a total of 30 salivary tumor cases have been benign, while only 4 (13.333) are malignant, from a total of 26 patents of parotid tumors, overall of 20(76.923) cases have been identified in superficial lobe, whereas only 6(23.076) cases have been in deep lobe, from a total of 30 salivary gland tumors, overall of 26(86.666) cases are pleomorphic adenoma and just 3 (11.538%) cases are mucoepidermoid carcinoma and only single case (3.333%) has been acinic cell carcinoma. Conclusions: The parotid gland has been defined as the major site of origin which is related to benign as well as malignant tumors, also the pleomorphic adenoma is the major benign salivary gland tumor and mucoepidermoid carcinoma is the major common malignant tumor. The rest of the cases are autoimmune disease and minor salivary gland tumors.
