Studying the epidemiological and clinical features of neck masses in Kerman, Iran

Background: Neck mass is one of the most common clinical findings in all age groups. Differential diagnosis of masses includes a range of pathologies from congenital to infectious or neoplasm. Understanding the risk factors of neck masses can help us to assess them properly. The purpose of this study is to obtain the epidemiological and clinical features of different neck masses in Kerman, Iran. Methods: This research was a descriptive, retrospective and cross-sectional study. 120 Patients that have been biopsied from neck masses during March 2014 to March 2018  in the otorhinolaryngology department of Shafa hospital of Kerman (referral center of otorhinolaryngology disease of southeastern Iran), were the participants of the study. Data regarding age, sex, history of addiction, smoking and definite pathologic diagnosis were collected and analyzed with SPSS 20th version. Results: Of 120 cases, 57.5 % were male and 42.5% were female. In the malignant masses group, the male to female ratio was 4.1 to 1. The average age of patients was 39.44 years old. From them, 20.83 percent had a history of smoking but 79.17 percent had never experienced smoking. In addition, 77.5% of the patients have not experienced opium consumption and 22.5% were addicted to opium regularly. There was a significant relationship between smoking and opium consumption and the incidence of malignant cervical masses (P<0.05). In the pathological study, inflammatory and infectious masses with 48.33 percent were in the head of pathology; malignant neoplasm with 25 percent, benign neoplasms with a prevalence of 12.5 percent and congenital masses with a prevalence of 9.7 percent were in the next ranks. Conclusion: In this study, we investigated the epidemiological and clinical features of neck masses in Kerman. It is obvious that smoking is an important risk factor for neck mass malignancies. Also, the present study revealed that the incidence of malignant tumors increased with age.
