The Relationship between Subcutaneous and Deep Abdominal Masses with Demographic Characteristics of Patients Referred to Amir Al-Momenin Hospital in Tehran During 2012 to 2023 years

Introduction: Considering the importance of prevalence and high complications of abdominal masses, this study was conducted to determine the prevalence of benign and malignant abdominal lesions and their relationship with demographic characteristics during a large 6-year study. Method: This analytical-cross-sectional study investigated the clinical records of 721 patients with subcutaneous and deep abdominal masses undergoing surgery in Amir Al-Mo’menin (AS) Hospital, Tehran, Iran, between the years 2012 and 2023, considering the inclusion criteria and using the convenience method. Moreover, demographic and pathology characteristics were extracted from these files. Results: Out of the total masses, 50 cases (6.9%) were malignant and the rest were benign. The most common benign masses were myoma (36.7%) and prostate hyperplasia (20.1%), and the most common malignant cases were bladder (16.0%) and ovarian (14.0%) in descending order. The age of people with malignant tumors was significantly higher than that of people with benign tumors (54.96 ± 15.23 vs. 45.42 ± 15.59 years; P<0.001). The prevalence of malignant cases in men was significantly higher than that in women (54.0% vs. 46.0%; P<0.001). However, there was no statistically significant relationship between the family history of abdominal mass (P=0.055) and the year of referral (P=0.259) with the type of mass. Conclusion: Abdominal malignant masses are more common in older ages and men.
