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.

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.

Simple mucin-type carbohydrate antigens Tn, sialosyl-Tn and T are often markers of neoplastic transformation and have very limited expression in normal tissues. We performed an immunohistological study of simple mucin-type carbohydrate antigens, including H and A variants, with well-defined monoclonal antibodies (MAb) on frozen and paraffin-embedded normal salivary gland tissue from 22 parotid, 14 submandibular, six sublingual, and 13 labial glands to elucidate the simple mucin-type glycosylation pattern in relation to cyto- and histodifferentiation. The investigated carbohydrate structures were predominantly observed in the cell cytoplasm, most often in the supranuclear area, suggesting localization to the Golgi region, whereas ductal contents were unstained. Mucous acinar cells expressed Tn, sialosyl-Tn, and H and A antigens, regardless of glandular location. Serous acinar cells, on the other hand, expressed A, H, and inconstantly sialosyl-T, Tn, and sialosyl-Tn antigens in major salivary glands, whereas serous cells of minor (labial) salivary glands expressed H exclusively, Tn and sialosyl-T antigens inconstantly, but never sialosyl-Tn and A antigens. The difference may be related to a more simple cytodifferentiation of serous cells of minor (labial) salivary glands as compared with major salivary glands. Duct cells in major salivary glands expressed A, H, and inconstantly T, sialosyl-T, and Tn antigens, whereas minor (labial) salivary glands ducts exclusively expressed H, T and sialosyl-T antigens, differences that may be related to dissimilarities in the duct system. Myoepithelial cells and basal cells exclusively expressed T and sialosyl-T antigens, which may prove useful in studies of salivary gland tumors, since these cells are known to play a key role in the histological characteristics of some salivary gland tumors. The results indicate a similar glycosylation pattern in the different major salivary glands, whereas minor (labial) salivary gland differ slightly in serous and duct cells. The limited and exclusive intracellular expression of the immature Tn, sialosyl-Tn, and T antigens indicates that these structures may be of value as markers of salivary gland tumors.

Polymorphous low-grade adenocarcinoma is a rare salivary gland malignant tumor of low aggressiveness, commonly occurring in minor salivary glands. Its origin in major salivary glands is considered exceedingly rare. We report a case of polymorphous low grade adenocarcinoma arising from left parotid in a 21-yearold female patient.Journal of Pathology of Nepal (2012) Vol. 2, 331-334DOI: http://dx.doi.org/10.3126/jpn.v2i4.6890

In modern conditions, the application of radiodiagnosis of salivary gland diseases requires a profound knowledge of the physical and technical bases and their scientific and methodological peculiarities. There are presented information on the history of discovery and diagnostic capabilities of some methods of radiation diagnosis. Analogue sialography at a certain stage of the application gave clinicians valuable information. In the diagnosis of inflammatory diseases, there is a predominance of traditional sialogram. The functional digital subtraction sialography allow us to eliminate traditional sialogram disadvantages. This method is considered the gold standard for the diagnosis of salivary ducts. Computer tomographic sialography is the most valuable for the diagnosis of salivary gland tumors, allows differential diagnosis between benign and malignant tumors. An important advantage of salivary gland scintigraphy in comparison with other imaging methods is that both the secretory function and the excretory fraction of all four major salivary glands. Glands can be simultaneously quantified using a single injection. The method of ultrasound diagnostics allows to detect both malformations and inflammatory, degenerative-dystrophic processes, has some clear advantages in comparison with sialography, scintigraphy, computed tomography, since neither x-ray nor magnetic field is used, the duration of the procedure is shortened, the tomographic plane can be easily manipulated, metal bodies do not interfere. Conclusion. Complex application of radiation diagnostic methods, development of algorithms for the diagnosis of salivary glands can become a source of accurate and practically meaningful information.
