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

Warthin tumor is the second most common benign salivary gland tumor that classically arises in the parotid gland. It can be synchronous, metachronous, multifocal, bilateral, or unilateral, which complicates diagnosis and management. Rare cases of Warthin tumor of the minor salivary gland are described, but no cases of unilateral, synchronous Warthin tumor involving the parotid and minor salivary gland have been reported. We present a case of Warthin tumor arising from a minor salivary gland in the left oropharynx of a 71-year-old male with a previous history of left parotid Warthin tumor, later determined to be synchronous.

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.

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

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.

Background. The presence of two or more tumor entities growing in adjacent locations within the salivary gland is very rare, and pathologic studies on such lesions are limited, particularly those with molecular information. Since the clinical history and imaging studies are usually nonspecific, accurate diagnosis and clinical management largely depend on a thorough histological examination. Methods and Results. We describe a 71-year-old man with an unusual case of hybrid salivary gland tumor composed of mucoepidermoid carcinoma and basal cell adenoma. Molecular analysis revealed differing driver genetic alterations in each component. Conclusions. Hybrid salivary gland tumors are rare, and their pathogenesis is controversial. The combination of mucoepidermoid carcinoma and basal cell adenoma has not been previously described. While malignant transformation of adenoma to carcinoma seems plausible, gene sequencing was more suggestive of their independent derivation. Key to appropriate surgical management is identifying the more aggressive component, ideally at the time of intraoperative consultation.

CONTEXT AND OBJECTIVE: Salivary gland tumor management requires long-term follow-up because of tumor indolence and possible late recurrence and distant metastasis. Adenoid cystic carcinoma (ACC) accounts for 10-15% of such tumors. The aim here was to evaluate surgical and clinical management, staging and follow-up of ACC patients in one academic institution. DESIGN AND SETTING: Retrospective study at Head and Neck Service, Universidade Estadual de Campinas. METHODS: Data on 21 patients treated between 1993 and 2003 were reviewed. Management utilized clinical staging, histology and imaging. Major salivary gland tumor extent was routinely assessed by preoperative ultrasonography. Diagnosis, surgery type, margin type (negative/positive), postoperative radiotherapy and recurrence (presence/absence) were evaluated. RESULTS: There were eleven major salivary gland tumors (52.3%), seven submandibular and four parotid. Ten patients (47.7%) had minor salivary gland ACC (all in palate), while the submandibular was the most frequently affected major one. Diagnoses were mostly via fine-needle aspiration (FNA) and incision biopsy. Frozen sections were used for six patients. There was good ultrasound/FNA correlation. Sixteen (76%) had postoperative radiotherapy. One (4.7%) died from ACC and five now have recurrent disease: three (14.2%) locoregional and two (9.5%) distant metastases. CONCLUSION: Adenoid cystic carcinoma has locally aggressive behavior. In 21 cases, of ACC, the facial nerve was preserved in all except in the few with gross tumor involvement. Treatment was defined from physical examination, imaging, staging and histology.

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
