Abstract
Lateral neck masses present clinically as neoplastic or non-neoplastic lesions of lymph nodes, salivary glands, and thyroid. Non-neoplastic lesions, if evaluated timely, may not transform into malignancy thus reducing clinical burden. A cytomorphological study using fine needle aspiration is a reliable method for the diagnosis of such masses. The aim of this study was to find out the prevalence of non-neoplastic lesions of lateral neck mass specimens received in the Department of Pathology in a tertiary care center. This descriptive cross-sectional study was carried out in the Department of Pathology among lateral neck mass specimens of a tertiary care center from January 2019 to December 2020 after obtaining ethical approval from the Institutional Review Committee (Reference no: 155/19). A convenience sampling method was used and data analysis was done in Microsoft Excel 2019. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Out of 300 lateral neck mass specimens, non-neoplastic lesions were found in 246 (82%) (77.7-86.3 at 95% Confidence Interval). The involvement of lymph nodes in 117 (47.6%) was the most common finding followed by thyroid 112 (45.5%). Among non-neoplastic lesions, the cytomorphological features of benign nodular goiter 93 (37.8%) was the most common lesion followed by reactive lymphoid hyperplasia 73 (29.7%). The study showed that the prevalence of non-neoplastic lesions was similar to that of other national and international studies.

Lateral neck masses present clinically as neoplastic or non-neoplastic lesions of lymph nodes, salivary glands, and thyroid
Out of 300 specimens collected in the study, the prevalence of non-neoplastic lesions was 246 (82%) (77.7-86.3 at 95% Confidence Interval)
Majority of the cases 37 (31.6%) among lymph nodes were in the age group 2029 years, 33 (29.5%) of the thyroid gland lesions were in the age group 50- 59 years and 4 (23.5%) of the cases of salivary gland lesions were in the age group 10-19 years
Summary
Lateral neck masses present clinically as neoplastic or non-neoplastic lesions of lymph nodes, salivary glands, and thyroid. The aim of this study was to find out the prevalence of non-neoplastic lesions of lateral neck mass specimens received in the Department of Pathology in a tertiary care center. Lateral neck mass is one of the common clinical problems which have a wide pathologic spectrum.[1] It can be congenital or acquired, neoplastic, or nonneoplastic. These can frequently present as enlarged lymph nodes which can be due to metastatic or inflammatory causes, thyroid disorders, or salivary gland tumors. Earlier evaluation of lateral neck masses with cytomorphological study avoids unnecessary surgeries in non-neoplastic or inflammatory conditions
