Abstract(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
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.
