Salivary gland tumors are neoplasms characterized by a high level of pleomorphism and histological overlap. One tumor may contain several cell types; therefore, it is necessary to include immunohistochemical staining, as well as morphometric analysis of tumor cells as prerequisites for an appropriate diagnosis. Our research included 120 tumors, such as pleomorphic adenoma, Warthin tumor, basal cell adenoma, myoepithelioma, adenoid cystic carcinoma, mucoepidermoid carcinoma, salivary duct carcinoma, polymorphous low-grade carcinoma and myoepithelial carcinoma. The aim of the study was to differentiate benign and malignant tumors based on the characteristics of nuclei. The expression of Ki67 and the morphometric nuclear parameters - area, perimeter, Feret diameter, integrated optical density, circularity, and roundness, were analyzed. It was observed that the Ki67 proliferative index was statistically significantly higher in malignant tumors (P<0.001). Adenoid cystic carcinoma exhibited the highest value, whereas the lowest value was exhibited in basal cell adenoma. Morphometric analysis showed statistically significantly increased values of integrated optical density (P<0.001) and nuclear size parameters (P<0.05) in malignant tumors. The determination of the Ki67 proliferative index and morphometric analysis of the integrated optical density and area can differentiate benign from malignant tumors with high precision. The presented values suggest the obtained results as cut-off values.

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.

Adenoid cystic carcinoma (ACC) is one of the most common salivary gland malignant tumors with a high risk of recurrence and metastasis. Current studies on cancer stem cells (CSCs) have verified that CSCs are the driving force behind tumor initiation and progression, suggesting that new cancer therapies may be established by effectively targeting and killing the CSCs. The primary goal of this study is to investigate the expression patterns of ABCG2, CD133, and podoplanin in ACC of minor salivary glands by immunohistochemistry analysis. We found that ABCG2 was weakly expressed in normal looking salivary gland tissues. A significant upregulation of ABCG2 expression in ACC was observed with a similar expression pattern of Ki-67. CD133 was detected in apical membrane of epithelial cells and podoplanin was expressed positively in myoepithelial cells of both normal looking tissue and ACC. However, no significant difference was found of the expression pattern of CD133 and podoplanin between normal looking tissues and ACC. Our observations suggest that CSCs may exist in quiescent cells with ABCG2 positive staining, which are surrounded by cells with positive expression of ABCG2 and Ki-67 in ACC, and costaining with ABCG2 and Ki-67 may help predict the location of CSCs.

AbstractA case of basal cell adenocarcinoma of the parotid gland is reported. Histologically it is to be distinguished from basal cell adenoma and adenoid cystic carcinoma. Clinically the presentation may appear benign. Surgical excision is the treatment of choice. The prognosis is uncertain because of lack of follow-up data.

IntroductionAdenoid cystic carcinoma, an uncommon malignant salivary gland neoplasm, is known for its long clinical course, indolent growth, neural invasion, local recurrence and late distant metastasis. Three distinct histological patterns have been identified, amongst which, solid pattern is the rarest one having the worst prognosis. Materials And MethodsA case of sixty year old male patient presented with a swelling in the left side of the neck, below the jaw gradually enlarging during the last three years. FNAC from the neck swelling was suggestive of benign adenoma of the salivary gland, possibly basal cell adenoma or pleomorphic adenoma. Submandibular gland was excised. Histopathological examination confirmed the solid pattern of adenoid cystic carcinoma, which is the rarest among the three distinct histological subtypes of the malignancy. DiscussionAdenoid cystic carcinoma is well known for its perineural spread. In cases of submandibular gland adenoid cystic carcinoma, surgical wide excision is very much possible and in T1 or T2 cases post-operative radiotherapy may not be needed. In our case, post operative radiotherapy was given for best local control, as the tumour showed histopathlogical solid variety, grade III pattern, which is known to have the worst prognosis.
