Introduction: Statistical study of neck masses and their evaluation and treatment methods have received much attention in journals and reference books. However, due to differences in the range of diseases and diagnostic-therapeutic facilities between different countries, it is necessary to achieve differential diagnoses of neck masses in Iran through regional studies.
Material and Methods: This study was a cross-sectional study that was conducted during 2018-2019 with the participation of 203 patients referred to the ENT clinics of Tabriz University of Medical Sciences. Patients with suspected neck masses underwent sampling and imaging after examination and their results were reported.
Results: In neoplastic lesions, the most involvement was in the jugulodysgastric lymphatic chain. In non-neoplastic lesions, the most common site of involvement was the anterior-middle part of the neck. In both sexes, the most common site of neck mass was in the jugulodigastric lymphatic chain, with a prevalence of 20% in men and 22% in women, respectively, with the difference that the percentage of neoplastic lesions in the area in both males and females was 36.86%, respectively and 55%.
Conclusion: A complete and frequent clinical examination is necessary in adults who are in their fourth decade of life. FNA is the best method after the examination if the cause of the mass is not known. After eliminating the inflammatory causes, SCC is the most common pathology in men and tuberculosis in women, which is often seen in the jugulodigastric lymph chain and posterior triangle of the neck, respectively.
