Characteristics and Outcomes of Parotid Gland Tumors in Adolescents

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.

Comparative study of fine needle aspiration cytology and histopathology of thyroid swellings in tertiary health centre

<p><strong>Background: </strong>Thyroid swelling being the most common presentation in ENT clinical practice, a prospective study was done to assess the role of Fine needle aspiration cytology in diagnosing the nature of thyroid swellings and comparing its results with histopathological examination findings.<strong></strong></p><p><strong>Methods: </strong>This is a prospective institutional based study comparing cytology and corresponding histopathology findings reported in 60 cases of thyroid swelling. The statistical analysis included sensitivity, specificity, positive predictive value, negative predictive value and accuracy in thyroid swelling.<strong></strong></p><p><strong>Results: </strong>Out of 60 cases, FNAC showed 93.3% and 6.6% of benign and malignant cases respectively whereas HPE showed 86.7% and 13.3% of benign and malignant cases respectively. On FNAC-HPE correlation using HPE as standard reference the diagnostic accuracy of present study is 91.66%.<strong></strong></p><p><strong>Conclusions: </strong>It was observed that FNAC is a reliable tool, safe and accurate method in evaluating thyroid swelling thus having great influences in treatment decision. Thus FNAC is the investigation of choice in thyroid swellings with excellent patient compliance, simple, safe and cost effective.<strong></strong></p>

“COMPARATIVE STUDY OF FNAC, USG, US-FNAC, AND HPE IN DIAGNOSIS OF NECK SWELLINGS”

ABSTRACT Aims: This prospective study was carried out to compare findings of the four procedures namely FNAC (fine-needle aspiration cytology), USG (ultrasonography), US-FNAC (Ultrasound-guided fine-needle aspiration cytology), and HPE (histopathological examination). MATERIAL AND METHODS Total 80 cases of different neck swellings were selected from ENT OPD at tertiary care hospital Prayagraj Uttar Pradesh. All cases underwent the preoperative procedure of FNAC,USG, US-FNAC and postoperative HPE for diagnosing the neck swelling. The results of FNAC, USG, US-FNAC w e r e c o m p a r e d a n d c o r r e l a t e d w i t h histopathology findings and conclusions drawn after statistical analysis. RESULTS More than half (56.25%) of neck swellings were of thyroid swellings. It was observed that sensitivity, specificity, PPV, NPV, accuracy of FNAC of all neck swellings were 85.71%, 91.78% ,50%, 98.53% ,91.25% respectively. Sensitivity ,specificity, PPV ,NPV , accuracy of all neck swellings of USG were 71.43%, 98.63%, 83.33% , 97.26% 96.25 respectively. Sensitivity ,specificity, PPV ,NPV , accuracy of all neck swellings of US-FNAC were 85.71% ,97.26% ,75% , 98.61%, 96.25 respectively. CONCLUSION The combined use of USG and FNAC give more accuracy for proper diagnosis of neck swelling than FNAC alone. The most accurate diagnosis of
