Objectives Kallikrein-related peptidase 10 (KLK10) has been implicated in the development of several types of cancer. The purpose of this study was to analyze the expression of KLK10 in 3 types of salivary gland tumour and normal salivary glands. Materials and methods: A standard immunoperoxidase staining technique was used to assess the Immunoexpression profile of KLK10 in normal salivary glands and 3 types of salivary gland tumour: pleomorphic adenoma, adenoid cystic carcinoma and mucoepidermoid carcinoma. Results Pleomorphic adenomas showed significantly lower KLK10 levels than control tissues. Neither of the malignant tumours (adenoid cystic carcinoma and mucoepidermoid carcinoma) showed a significant alteration in the immunoreactive scores of KLK10 in comparison with the normal salivary gland tissues. KLK10 immunoreactive scores were comparable in adenoid cystic carcinoma and mucoepidermoid carcinoma. Pleomorphic adenoma had significantly lower levels of KLK10 than mucoepidermoid carcinoma. Conclusions The finding of lower KLK10 levels in pleomorphic adenoma suggests aberrant expression in a tumour that develops primarily from myoepithelial cells. A kallikrein cascade may play a role in the development and/or outcome of some salivary gland tumours.

Malignant tumours of the salivary glands in children are extremely rare. We present here a 12-year-old girl initially diagnosed as pleomorphic adenoma on fine needle aspiration biopsy, and adenoid cystic carcinoma (ACC) after the lesion was excised and examined by histopathology. A wide resection of the lesion and bilateral supraomyohyoid neck dissection was performed. To our knowledge this is one of the youngest patients with ACC of the minor salivary glands. Due to its benign histological appearance, the biological agressiveness of ACC is usually underestimated. Although fine needle aspiration cytology (FNAC) is very valuable in diagnosis, cytological variations of pleomorphic adenoma must be considered. ACC of the tongue in a young age group should be treated with wide resection and selective neck dissection if the tumour is localized in places where the risk of metastasis is increased and if there is a clinically palpable lymph node. In such cases the clinician should not avoid radical operations even in a young patient.

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.

Functional Features

A series of 20 cases of pleomorphic adenoma and 19 cases of adenoid-cystic carcinoma of the salivary glands, and one case in the mammary location, were investigated regarding immunohistochemical reactivity for Tissue Polypeptid Antigen (TPA), Pre-Keratins, Vimentin, S-100 Protein, and their arrangement pattern of fibronectin. As a whole, the results support the hypothesis of morpho-structural and mainly, onto-histogenetic similarities between these tumours, but they also underline the need for great care in outlining their morpho-functional features, in relation to their different prognoses.

Background: Adenoid cystic carcinoma (AdCC) and mucoepidermoid carcinoma (MEC) are the commonest salivary gland malignancies in Pakistan constituting almost 75% of all malignant salivary gland tumours.Objective: The objective of this study was to determine the expression of galectin-3 (Gal-3) in AdCC and MEC of salivary glands and to see its relationship with histological differentiation in these tumours.Method: This descriptive study was conducted at the Department of Morbid Anatomy and Histopathology/ Oral Pathology, University of Health Sciences Lahore, Pakistan. Biopsies and detailed clinical data of 20 cases each of adenoid cystic carcinoma and mucoepidermoid carcinoma reported at local tertiary care hospitals from Jan. 2014 to Sep. 2015 were retrieved. The histologic diagnosis was made on Hematoxylin and Eosin staining. The tumours were graded into grades I, II & III according to the most recent grading criteria. AdCC was studied with respect to its morphological patterns (tubular, cribriform and solid) while MEC was studied with special concern to the cell types seen in it (mucous, intermediate, squamous and clear cells). Immunohistochemical expression of galectin-3 was determined in these tumours with respect to histological grades, patterns and cell types seen.Results: Moderate positivity (55%) for anti-galectin-3 antibody was the most frequently observed score for galectin-3 in both MEC and AdCC. Moderate positive (55%) staining reaction was followed by weak positive (30%) staining reaction in AdCC. Total score for antigalectin-3 antibody, positive stromal reaction (intensity) and location of cellular signals for anti-galectin-3 antibody were all found to be significantly associated with grades of AdCC. Also, histological pattern of AdCC (tubular, cribriform and solid) were significantly associated with type of anti-galectin-3 staining pattern of cells (p<0.001). In MEC, moderate positive (55%) staining for anti-galectin-3 antibody was followed by strong positive reaction (30%). The total score for anti-galectin-3 antibody was significantly associated with grades of the tumour and lymph node status. Also, the type of staining reaction in cells was significantly associated with cell type (mucous, squamous and intermediate cells).Conclusion: It can be concluded from the current study that expression of Gal-3 decreases with decreasing differentiation in parenchyma of malignant tumours while its expression in tumour extracellular environment increases with increasing grade of the tumour.Also, it can be concluded that nuclear expression of Gal-3 is associated tumour differentiation and cytoplasmic expression with tumour cell proliferation.
