Introduction: The paper aims to demonstrate the Clinic’s and own research in the treatment of major salivary gland tumors. Material and method: In the years 2013–2019, there were 95 salivary gland surgeries, including 45 performed in women (47.36%) aged between 24 and 82 and in 50 men (52.64%) aged 29 to 86. Diagnostics of major salivary glands included: patient history, otolaryngological examination, ultrasound and fine needle aspiration (BACC) (of tumor), laboratory tests (morphology, CRP) and computed tomography (CT) or magnetic resonance imaging (MRI) to accurately assess salivary glands, location of lesion and lymph nodes prior to elective surgery. Research results: In the analyzed material patients with major salivary gland tumors were most frequently operated on at the age of 61–70 (34.7%) and 51–60 years (23.2%). Most patients with tumors were hospitalized in the last 4 years between 2016–2019, which accounted for 77.8% of all operated cases. Among the operated lesions, benign neoplasms and tumors occurred in 93.7%, of which the most frequent findings in histopathological examination were Warthin tumor in 50.5%, and multiform adenoma in 26.3%. The remaining tumors and benign neoplasms constituted only 16.9% and were observed in isolated cases, including eosinophilic adenoma, lymphoepithelial cyst, myoepithelial adenoma, lipofibrosarcoma, congestive cyst, air cyst, tubular adenoma, basal cell carcinoma, cyst with squamous metaplasia features, vascular malformation. Malignant salivary gland tumors were found in 6.3%, including the following malignant tumors were revealed histopathologically: adenocarcinoma, mucoepidermal carcinoma, acinocellular carcinoma, epithelialmyoepithelial carcinoma, ductal carcinoma. Conclusions: The majority of operated salivary gland tumors were benign (93.7%), of which the most common histopathologically were: Warthin tumor (50.5%) and multiform adenoma (26.3%), while malignant tumors occurred in 6.3%. Tumors were localized mainly in the parotid gland in as many as 93.7% cases, of which the most common localization concerned the superficial lobe in 56.8%. The most frequent surgical technique used in the Clinic was extracapsular dissection of the tumor in 88.4%, and other methods were used rarely.

Background: Salivary gland tumors include a wide variety of benign and malignant tumors in the oral and maxillofacial region. Although these tumors are not common, they are not rare. The prevalence of these tumors varies with regard to age, gender, and their location in the body. Objectives: This study aimed to evaluate the frequency of benign and malignant salivary gland tumors in patients referred to three referral hospitals in Tehran, Iran. Methods: This retrospective cross-sectional study examined the demographic and pathologic records of the patients with salivary gland tumors submitted to the Department of Pathology of Amir Alam, Loghman Hakim, and Shohada Hospitals from 2005 to 2016. In this study, the histological variants of salivary gland tumors and clinical parameters such as age, gender, and the location of the tumor were examined. The clinical data were analyzed using SPSS software version 21. Results: Of 137632 patient records, 1180 cases were salivary gland tumors. Pleomorphic adenoma in 794 cases (67.3%) and adenoid cystic carcinoma in 109 cases (9.2%) were the most common tumors, respectively. Salivary gland tumors were more common in males, and the participants’ mean age was 42.86 ± 16.5 years. The most common site was parotid and minor salivary glands, with 937 (79.4%) and 137 (12%) cases, respectively. Conclusions: In this study, the most common benign tumor was pleomorphic adenoma in the parotid gland, and the most common malignant tumor was adenoid cystic carcinoma in the major salivary glands. Furthermore, benign tumors were more frequent than malignant tumors.

Objective To analyze the expression of human kallikrein 14 (KLK14) in salivary gland tumors. Methods A standard immunoperoxidase staining technique was used to assess the expression profile of KLK14 in normal salivary glands and tumors including pleomorphic adenoma (PA; n=17), adenoid cystic carcinoma (ACC; n=13) and mucoepidermoid carcinoma (MEC; n=9). Tumor stage, grade, patient age and gender, and site of occurrence were recorded. These clinical parameters were correlated with KLK14 levels in malignant tumors. The expression profiles for KLK3, 5, 6, 8 and 13 were also retrieved. Results Normal salivary glands, PA, ACC and MEC showed strong expression of KLK14 in ductal and non-ductal cells. Both PA and ACC showed higher KLK14 levels than normal glands and MEC tissues. There were no statistically significant associations between levels of KLK14 and clinical parameters. Conclusions The differences in the levels of KLK14 suggest that KLKs may aid in the differential diagnosis of salivary gland tumors. The coexpression of KLKs suggests their possible involvement in an enzymatic pathway activated in salivary gland. KLK14 may be a promising new biomarker in salivary gland tumors.

There are four clinicopathologic categories of the exclusively major salivary gland tumors that present in the perinatal period. The two with the smallest representation among the 20 cases reported to date are those with a hamartomalike appearance and those with benign adult equivalents — The pleomorphic and monomorphic adenomas. Five cases have been undifferentiated or basaloid salivary carcinomas. Embryomas (sialoblastomas) are the most numerous. These tumors manifest a histologic phenotype like that of the epithelial anlage of the salivary glands, albeit in an arrested state of differentiation.

AbstractSaliva is responsible for various functions from lubrication to digestion. The saliva is secreted by numerous minor and major salivary glands. These salivary glands are sometimes affected by various local and systemic inflammatory conditions, obstructive pathologies with benign and malignant tumors. This chapter deals with various pathologies of salivary glands and their management.

Abstract Objective.—CD34-positive dendritic interstitial cells may be associated with the regulation of tumor growth. This association has been studied in various human neoplasms, especially skin tumors. In this study, we evaluated the distribution of dendritic interstitial cells and myofibroblastic cells at the tumor periphery of various benign and malignant salivary gland neoplasms. Methods.—Forty-nine cases of salivary gland tumors were selected: 16 pleomorphic adenomas, 12 Warthin tumors, 8 polymorphous low-grade tumors, 5 adenoid cystic carcinomas, 6 acinic cell carcinomas, and 2 mucoepidermoid carcinomas. Immunohistochemical analysis was performed by using antibodies for CD34 (dendritic cells) and α-smooth muscle actin (myofibroblast) on formalin-fixed, paraffin-embedded archival tissue. Staining intensity was graded as marked (3+), moderate (2+), weak (1+), and absent (0). Results.—Staining intensity for CD34 was 3+ in 24 (86%) of 28 benign tumors (pleomorphic adenomas and Warthin tumors) and 6 (29%) of 21 malignant tumors (polymorphous low-grade tumors, acinic cell carcinomas, adenoid cystic carcinomas, and mucoepidermoid carcinomas) and 2+ in 4 (19%) of 21 malignant tumors. None of the benign tumors displayed 2+ staining with CD34. Three (11%) of 28 benign and 11 (52%) of 21 of malignant tumors failed to stain with CD34. α-Smooth muscle actin staining was 3+ in 10 (36%) of 28 benign tumors and 6 (29%) of 21 malignant tumors, and 2+ in 11 (39%) of 28 benign and 2 (9%) of 21 malignant tumors. Five (18%) of 28 benign and 11 (52%) of 21 malignant tumors failed to stain with α-smooth muscle actin. Conclusion.—We conclude that the dendritic interstitial cells and myofibroblastic cells may be associated with the regulation of tumor growth in salivary gland tumors.
