Objective Parotid tumors are rare neoplasms in adults but are exceedingly infrequent in adolescents. We aimed to determine the clinical characteristics and outcomes of parotid tumors in adolescents under 20 years old. Methods Between 1999 and 2020, 979 cases of benign parotid tumors and 236 cases of malignant parotid tumors were treated surgically in our department. Of these, 12 benign cases (1.2%) and 9 malignant cases (3.8%) were in adolescents. There were no benign or malignant cases for those aged under 10 years. Results Regarding the histological type, all benign tumors were pleomorphic adenomas. About half of malignant tumors were mucoepidermoid carcinomas, and excluding one high-grade case, the grade of malignancy was all low/intermediate. The accuracy of fine-needle aspiration cytology among adolescents showed no significant difference with that of adults. In contrast to adults, adolescent benign tumor cases showed a markedly high rate of pleomorphic adenomas and no postoperative facial nerve palsy. Malignant tumors in adolescents had a different trend than adults; low/intermediate-grade malignancies were common and thus few symptoms/signs of malignancy could be observed. As well, the accuracy of fine-needle aspiration cytology was poor. All cases had a good prognosis and are disease-free survival. Conclusion Parotid tumors in adolescents are rare but have several characteristics that are distinct from adults. As long-term observation is required posttreatment in adolescent patients, recurrence in benign pleomorphic adenomas and poor long-term prognosis in malignant tumors, especially for those with low/intermediate-grade malignancy, are more likely to be observed.

AbstractIntroduction: Masses of the head and neck comprise a variety of benign and malignant tumors and tumor-like conditions, which may present diagnostic challenges to the surgeon and pathologist as well. Fine needle aspiration cytology is considered to be a valuable diagnostic tool used for preoperative evaluation of various masses in the head and neck region. However, its role is quite controversial for salivary gland tumour evaluation. This study was aimed to evaluate salivary gland fine-needle aspiration cytology for sensitivity, specificity and diagnostic accuracy in our medical center.Material and method: The present study included 58 patients with different salivary gland lesions who underwent preoperative fine-needle aspiration procedure followed by surgical procedure and histological examination. The cytological findings were compared with the final histological diagnosis and concordance assessed.Results: Of the 58 cases with salivary gland lesions, most of them involved parotid gland (72.41%), 91.38% were neoplasms and 8.62% were non-neoplastic lesions. Out of 53 neoplasms, 39 were benign and 14 were malignant salivary gland tumors. The sensitivity and a specificity of fine-needle aspiration cytology in differentiation malignancies from benign lesions was 100% and 97.73% respectively. In some situations cytological features could not provide correct tumor characterization.Conclusions: Fine-needle aspiration cytology is a simple and reliable technique for preoperative evaluation of salivary gland tumors with a high sensitivity diagnosis of malignant tumors, but a lower tumor type characterization. Due to the minimally invasive nature of the technique, fine-needle aspiration cytology offers valuable information for planning of subsequent therapeutic management.

Introduction- Evaluation of diagnostic accuracy of fine needle aspiration cytology (FNAC) in salivary gland neoplasms. Materials and method – this is a crossectional study provides analysis of 82 salivary neoplasms out of 244 salivary FNAC during the period September 2011 to august 2014. All non neoplastic lesions were excluded from the study.All age group and both sex were included. FNAC results were  reviewed, the morphology of individual cells and their patterns in the smears were studied  in detail  and diagnosis were made. Histopathological studies were done whenever possible and were considered the gold standard. Results – The study included 82 cases, male to female ratio was 1.2 :1 ; commonly involved age group was 20 to 40 years. Fiftyfive cases (67.07%) were diagnosed as benign, 27 cases (32.93%) as malignant tumors. Pleomorphic  adenoma(59.76%) was most common benign neoplasms and mucoepidermoid carcinoma(23.17%) was most common malignant neoplasms. Parotid was most frequently involved gland(63.41%).Benign tumors common in parotid gland malignant tumors common in submandibular gland.Diagnostic accuracy was found to be 94.87% with false negative rate 5.1%. Conclusion – FNAC of salivary gland proved to be  a highly accurate initial diagnostic test for preoperative evaluation of salivary neoplasms.
