Introduction: Due to the different complications caused by Henoch-Schonlein purpura and in order to prevent additional treatment costs for patients, we decided to investigate the clinical features of cases of Henoch-Schonlein purpura. Materials and Methods: In this descriptive cross-sectional study, 52 children in whom the diagnosis of Henoch-Schonlein purpura was confirmed were enrolled in the study from 2009 to 2016. The instruments of this research include a researcher-made questionnaire with two parts. The first part is related to demographic characteristics including age, sex and season of referral and the second part was related to morbidity such as various symptoms. Data were collected from patients’ records and interviews with families and were analyzed using SPSS V.22.

Results: Out of 52 patients, 30 (57.7%) were boys and 22 (43.3%) were girls. The mean age of patients was 3.02 to 6.58 years. Autumn and winter had the most clients of Henoch-Schonlein purpura. One of the most common manifestations seen in most patients was cutaneous manifestations. There was no significant relationship between gender and clinical manifestations and seasons of the year with these manifestations (p> 0.05). The results showed that age was significantly associated with renal manifestations (P <0.05). Conclusion: The results of this study showed that the prevalence of Henoch-Schonlein purpura disease is higher in boys. Cutaneous manifestations were seen in most patients and in patients with renal manifestations, the mean age was higher and significant.
