Introduction: Salivary gland tumors are a heterogeneous group of neoplasms that are relatively rare but represent a wide variety of both benign and malignant histopathologic subtypes. The aim of this study was to find out the histopathological distribution of primary salivary gland tumors and correlate fine needle aspiration cytology reports with histological findings.Materials and Methods: A total of 83 patients attending the otorhinolaryngology department with salivary gland tumors were enrolled in our study. The histopathological findings were reported and correlated with cytological findings.Results: The mean age of the patient with salivary tumors was 43.11 ± 13.02 years. Out of 83 cases, 3 (3.6%) patients were diagnosed as inflammatory lesions, 64 (77.1%) patients had benign salivary gland tumors and 16 (19.3%) of patients had malignant salivary glands tumors in histopathology. The sensitivity and specificity of FNAC in this series for detecting salivary gland malignancy were 68.8% and 98.5% respectively with an overall diagnostic accuracy of 92.8%. The most common salivary gland tumor was found to be pleomorphic adenoma (56.6%) and the most common malignant salivary gland tumor was found to be mucoepidermoid carcinoma (19.3%). The comparison of the incidence of salivary gland tumors in various age groups showed a statisticallysignificant difference (p=0.009).  Conclusions: Benign salivary tumors are more common than malignant tumors with the most common occurrence in parotid glands. Pleomorphic adenoma is the most common benign tumor whereas; mucoepidermoid carcinoma is the most common malignant tumor in patients visiting Nobel medical college.

Background: The tumors of the salivary glands are uncommon head and neck neoplasms. The aim of this study was to evaluate the relative frequencies, types, site distribution and the histopathological features of salivary gland tumors. Materials and Methods: This was a retrospective study of 176 cases of salivary gland tumors collected from medical record section and department of pathology at B.P.Koirala Memorial Cancer Hospital from Jan. 2005 to Dec. 2010. Tumors were analyzed based on demographics, anatomic location and histopathological type. Results: Out of 176 cases, 66 (37.5 %) were benign and 110 (62.5 %) were malignant with M:F ratio of 1.7:1. The mean age observed was 44.76 years with age range of 12 to 75 years. Pleomorphic adenoma was found to be the commonest benign tumor (72.7 %), followed by Warthin tumor (15.1%), monomorphic adenoma (3.0 %) and basal cell adenoma (3.0 %). The mucoepidermoid carcinoma was the most common malignant tumor (38.1 %), followed by adenoid cystic carcinoma (25.4%), acinic cell carcinoma (10.9%), adenocarcinoma NOS (6.3%), carcinoma ex pleomorphic adenoma (5.4%) and unclassified malignant tumor (4.5 %). Parotid was the most common site for the location of tumors (70.4%) followed by submandibular (19.3%) and minor salivary glands (10.2 %). Conclusion: Pleomorphic adenoma was the commonest salivary gland tumor observed in both sexes. Mucoepidermoid carcinoma was the most common malignant salivary gland tumor. The parotid gland was the most common site of origin in both benign and malignant tumors. DOI: http://dx.doi.org/10.3126/jpn.v4i7.10291 Journal of Pathology of Nepal (2014) Vol. 4, 520-524

ABSTRACT Background Salivary gland tumors constitute about 3% of all head and neck tumors. We present a series of 104 cases of various salivary gland pathologies and the various modalities of surgeries done between January 2007 and July 2017. Materials and methods Total 104 patients with salivary gland tumors were included in this study, of which 76 patients had parotid tumors and 28 were submandibular gland tumors. The presence or absence of coexisting salivary gland stones, involvement or noninvolvement of ducts were all considered. Preoperatively, patients underwent fine needle aspiration cytology (FNAC) and imaging studies along with routine blood investigations. Results All patients underwent surgery and subsequent histopathological examination (HPE). The preoperative FNAC and postoperative HPE were not correlating in 6.5% of parotid tumors and in 3.5% of submandibular gland tumor. Anomalies in the fasciovenous planes were seen in 3% of the patients, which caused intraoperative difficulties. Postoperatively, five patients had salivary leak and three patients had neuropraxia, which was managed conservatively and the patients recovered subsequently between 3 months and 6 months postoperatively. Conclusion Surgery for salivary gland tumors has its own threats due to the close proximity of nerve, vessels, and ducts. Postoperative complications like nerve palsy is seen more common in malignant tumors in both parotid and submandibular gland tumors. A proper methodical assessment and awareness of the various anatomical anomalies intraoperatively may give good surgical outcomes in surgeries of salivary gland tumors. In our study, various anomalies were encountered and dealt appropriately. How to cite this article Vemuru T, Mohanty S, Manimaran V, et al.

Salivary gland tumors are a rare tumor entity within malignant tumors of all tissues. The most common are malignant mucoepidermoid carcinoma, adenoid cystic carcinoma, and acinic cell carcinoma. Pleomorphic adenoma is the most recurrent form of benign salivary gland tumor. Due to their low incidence rates and complex histological patterns, they are difficult to diagnose accurately. Malignant tumors of the salivary glands are challenging in terms of differentiation because of their variability in histochemistry and translocations. Therefore, the primary goal of the study was to review the current literature to identify the recent developments in histochemical diagnostics and translocations for differentiating salivary gland tumors.

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.

Background: Salivary gland tumors are rare, generally benign and affect both major and minor salivary glands.Objective: To find out the pattern of distribution of different benign and malignant salivary gland epithelial tumors and their relation to age and sex in a tertiary care center in Bangladesh.Methodology: This is a retrospective study. Details of epithelial salivary gland tumors were obtained from department of ENT, National institute of cancer & research hospital (NICRH), Dhaka, Bangladesh from the period January 2009 to December 2012 (3 years).Result: A total number of 261 cases presenting with both benign and malignant salivary gland tumors were analyzed according to gender, age and histopathological findings. There were 130 (49.84%) males and 131 (50.19%) females with the male female ration of 1: 0.99. Age of study population ranged from 10 to 70 years with the mean age 40.78. Percentage of benign salivary gland tumors was 73.94% and malignant salivary gland tumor 26.05%. Among major salivary gland tumors, no sublingual tumors were found and parotid gland tumors were the commonest. Whereas, among minor salivary gland tumors palatal minor salivary tumors were common.Conclusion: Parotid gland was the most common site of origin of both benign and malignant salivary gland tumors. Histopathologically, pleomorphic adenoma was the most common benign salivary gland tumor and mucoepidermoid carcinoma was the most frequent malignant neoplasm. Adenoid cystic carcinoma was common minor salivary gland tumor.Bangladesh Journal of Medical Science Vol.15(1) 2016 p.90-94

e17592 Background: Salivary gland tumors are rare, comprising only 6 to 8 percent of head and neck neoplasms. Most of them are benign and commonly occur in the parotid gland. In the last decade elevated hematological inflammatory parameters like neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) were identified as predictive and prognostic factors in various malignancies. The aim of this study was to evaluate the differences of preoperative of NLR and PLR levels in benign and malignant causes of salivary gland tumors. Methods: This retrospective study was made of a total of 133 patients with salivary gland tumors (age range: 17-89 years; 68 male and 65 female) who were treated between January 2006 and May 2016. Preoperative counts and levels of hematological parameters were obtained from the recorded computerized database in benign and malignant tumors. Results: NLR and PLR levels were significantly higher in the malignant salivary gland tumor group than the benign group( NLR: 0.66±1.3 vs 0.59±0.31 p=0.001, PLR: 160.3±85.7 vs 124.6±44.1 p=0.014). Conclusions: The results of the current study revealed the potential predicitve role of NLR and PLR in patients with salivary gland tumors. These cheap and easily available blood count parameters could be useful biomarkers in the future; but further investigations are needed to confirm our findings. [Table: see text]

Objective: To present a case of carcinoma ex pleomorphic adenoma in the parapharyngeal space and discuss its management.   Methods: Design:            Case Report Setting:           Tertiary Government Teaching Hospital Subjects:         One   Results:  A 40-year-old male patient with dysphagia for three months and a left-sided mucosa-covered oropharyngeal mass was found to have a prestyloid parapharyngeal lesion on CT Scans. Fine Needle Aspiration Cytology (FNAC) revealed a pleomorphic adenoma. With a past history of parapharyngeal pleomorphic adenoma excised transorally three years before, the present mass was excised by mandibular swing approach. Post-operative recovery was uneventful, but the final histopathological report was carcinoma ex pleomorphic adenoma.   Conclusion: Malignant transformation should be suspected in recurrent salivary tumors in the parapharyngeal space. Provided there was truly no pre-existing malignant focus in the originally-excised tumor, and that early recurrence was not due to inadequate initial excision, this patient had a rare condition where the same tumor underwent malignant transformation within 3 years only. To the best of our knowledge, such an early transformation to malignancy of a minor salivary gland tumor of the parapharyngeal space has not been reported in the English literature.   Keywords: carcinoma ex pleomorphic adenoma, pleomorphic adenoma, carcinoma,  parapharyngeal space, malignant, transformation, minor salivary gland tumor,  mandibular swing

Pleomorphic Adenomas

Background: A pleomorphic adenoma is the most common salivary gland neoplasm in both children and adults. Pleomorphic adenomas are derived from ductal and myoepithelial cells and are most commonly found in the superficial lobe of the parotid gland. The purpose of this article is to discuss the genes involved in pleomorphic adenomas and the possible autosomal dominant mode of inheritance. Case Description: The first patient was a white male who was diagnosed with carcinoma ex pleomorphic adenoma, a highly aggressive tumor, at the age of 57. He had an undiagnosed pleomorphic adenoma for approximately 15 years prior. The tumor was excised and the patient underwent radiation in the location of his parotid gland for 4 years until he deceased. The second patient is a white female, his daughter, who was diagnosed with a benign pleomorphic adenoma at the age of 46. Her salivary gland tumor was excised and normal follow up appointments occurred. Practical Implications: Pleomorphic adenomas most commonly affect the parotid gland, the largest of the three major salivary gland tumors. Occurrence and excision of this salivary gland tumor will cause a decrease in the secretion of saliva, leading to a dry mouth and an increased risk of caries.

ABSTRACT Mucoepidermoid carcinoma ex pleomorphic adenoma (MCxPA) is a rare salivary gland tumor predominantly found in major salivary glands. A case of MCxPA involving the soft tissue and bone of the retromolar region of a 26-year-old man is presented. The histopathological features revealed a neoplasm with predominance of pleomorphic adenoma (PA) elements, and presence of mucoepidermoid carcinoma malignant epithelial cells in several areas. Histochemical and immunohistochemical studies were positive for periodic acid Schiff, alcian blue, cytokeratins 7, 13, 14, and 19, Bcl-2, c-erbB-2, FGF-2 and maspin in the malignant areas. The patient underwent a partial resection of the left side of the mandible with neck dissection and MCxPA diagnosis was confirmed.
