Objectives: To evaluate epidemiological pattern, early diagnostic tool and histological type of parotid gland tumors. Study Design: Prospective cross sectional study. Setting: Department of Oral & Maxillofacial Surgery& General Surgery Liaquat University hospital Hyderabad. Period: From 2013 to 2017. Material & Methods: Study contains 67 patients of parotid tumors after initial diagnosis. These patients were first diagnosed by FNAC (Fine needle aspiration cytology) along with CT scan & MRI where required. Final diagnosis was established after histopathological diagnosis of tumor. Results: Males were predominantly involved in both tumor patterns. Most common age group was 5th decade in both benign and malignant tumors. FNAC has diagnostic sensitivity of almost 90-97%. Out of 67, 51 tumors were benign and 16 were malignant. Pleomorphic adenoma was the most common benign tumor while mucoepidermoid carcinoma was found as most received malignant tumor. Conclusion: Pleomorphic adenoma is most commonly found benign tumor and mucoepidermoid carcinoma is found more in numbers as malignant tumor.

Abstract: Salivary glands tumours are relatively rare to find. There is still no adequate data about the incidence of salivary gland tumours in Indonesia. The main objective of this research was to cognise the profile of salivary glands tumours patients in Prof. Dr. R.D. Kandou Central General Hospital Manado from July 2012 to June 2015. Methods used is descriptive retrospective. The results showed there are 37 patients with salivary gland(s) tumour(s). Male was 59,5% and female was 40,5%. By age groups found that <19 years for 2.7%, 19-30 years for 8,2%, 31-45 years for 21.6%, 46-60 years for 37,8%, >60 years for 29,7%. Based on the histopathological classification, pleomorphic adenoma for 56.8%, Whartin's tumor for 8.1%, myoepithelioma for 2,7%, basal cell adenoma for 2.7%, oncocytoma for 2.7%, cystadenoma for 5.4%, canalicular adenoma for 2.7%, mucoepidermoid carcinoma for 10.8%, adenocarcinoma for 5.4%, and acinic cell carcinoma for 2.7%. Based on the location of the tumours’ appearance, parotid gland for 83.8%, submandibular gland for 13.5%, minor salivary glands for 2.7%. Based by the incidences annually, first year for 21.6%, second year for 32.3%, and the third year for 46.1%.Conclusion: Males are more than females, most commonly found in the age group of 51-60 years, the most commonly benign tumour found is the pleomorphic adenoma, the most commonly found malign tumour is mucoepidermoid carcinoma, the most commonly location of the tumours’ appearance is the parotid gland. The salivary glands tumours continued to increase during the last three years.Suggestion: Still necessary to do further research about salivary glands tumours.Keywords: salivary glands tumours, age, gender, histopathology, location, profileAbstrak : Tumor kelenjar liur adalah tumor yang relatif sedikit dijumpai ditemukan. Belum ditemukan data yang lengkap tentang kejadian tumor kelenjar liur di Indonesia. Tujuan utama dari penelitian ini adalah untuk mengetahui profil penderita tumor kelenjar liur di RSUP Prof. Dr. R.D. Kandou Manado periode Juli 2012-Juni 2015. Metode penelitian yang digunakan adalah deskriptif retrospektif. Hasil penelitian memperlihatkan terdapat 37 penderita tumor kelenjar liur. Laki-laki sebanyak 59,5% dan perempuan 40,5%. Kelompok usia <16 tahun sebanyak 2,7%, 16-30 tahun sebanyak 8,1%, 31-45 tahun sebanyak 21,6%, 46-60 tahun sebanyak 37,8%, >60 tahun sebanyak 29,7%. Berdasarkan klasifikasi histopatologi jenis pleomorphic adenoma sebanyak 56,8%, Whartin’s tumor sebanyak 8,2%, myoepithelioma sebanyak 2,7%, basal cell adenoma sebanyak 2,7%, oncocytoma sebanyak 2,7%, cystadenoma sebanyak 5,4%, canalicular adenoma sebanyak 2,7%, mucoepidermoid carcinoma sebanyak 10,8%, adenocarcinoma sebanyak 5,4%, acinic cell carcinoma sebanyak 2,7%. Berdasarkan lokasi munculnya tumor, kelenjar parotis sebanyak 83,8%, kelenjar submandibula sebanyak 13,5%, kelenjar liur minor sebanyak 2,7%. Berdasarkan jumlah pertahunnya, tahun pertama sebanyak 21,6%, tahun kedua sebanyak 32,3%, dan tahun ketiga sebanyak 46,1%.Kesimpulan : Penderita laki-laki lebih banyak daripada perempuan, paling banyak ditemukan pada kelompok usia 46-60 tahun, tumor jinak yang paling banyak ditemukan adalah pleomorphic adenoma, tumor ganas yang paling banyak ditemukan adalah mucoepidermoid carcinoma, lokasi tersering munculnya tumor adalah kelenjar parotis. Penderita tumor kelenjar liur terus meningkat selama tiga tahun terakhir.Saran : Perlu dilakukan penelitian lebih lanjut tentang tumor kelenjar liurKata Kunci : tumor kelenjar liur, usia, jenis kelamin, histopatologi, lokasi, profil

<p class="abstract">Oncocytoma of parotid gland is a rare tumor that mainly affects the age groups of sixth to eight decades. The treatment of this tumor is mainly surgical with either radical or superficial parotidectomy and<em> </em>the prognosis is excellent. In our case report, 72 years old female came with complain of slowly growing, painless swelling on right infra auricular area which was diagnosed as oncocytoma of parotid gland. She was successfully treated with superficial parotidectomy. Since the oncocytoma of parotid gland is very rare tumor and may confuse with other parotid diseases like pleomorphic adenoma, mucoepidermoid carcinoma. As the cure rate of the disease is excellent, so it is advised to make the appropriate diagnosis whenever the case is encountered.</p>

Background: Salivary gland tumors constitute a highly heterogeneous histopathologic group. There are few epidemiological studies of large series of benign and malignant epithelial tumors of major salivary glands in South India.Methods: This is a retrospective study in a tertiary care centre in Kerala, South India. A total of 180 epithelial neoplasms of major salivary gland were studied over a 5 year period. In each case age, sex, anatomical location and histopathological diagnosis were recorded.Results: Patients with benign and malignant tumors presented with a mean age of 52.3 and 55.9 years respectively. The frequency of benign tumors was 80.6% (n = 145) and of malignant tumors was 19.4% (n = 35). There was a higher prevalence of tumors in males 60.6% (n = 109) than in females 39.4% (n = 71). 91.9% (n = 164) of the tumors were localized in the parotid gland, 8.3% (n = 15) in the submandibular gland and 0.6% (n = 1) in the sublingual gland. The most common benign tumors were Pleomorphic adenoma (48.9%, n = 88) and Warthin’s tumor (28.9%, n = 52). Among malignant tumors, Mucoepidermoid carcinoma was the most common (9.5%, n = 17) followed by Carcinoma ex pleomorphic adenoma (2.8%, n = 5) and adenoid cystic carcinoma (2.2%, n = 4).Conclusions: Parotid gland was the most common site of both benign and malignant tumours. Plemorphic adenoma was the most common benign tumor and mucoepidermoid carcinoma was the most common malignant tumor.
