Objective: To compare pediatric-onset psoriasis and adult-onset psoriasis in terms of frequency of gender involved, family history, trigger factors, and sites involved at onset. Study Design: Comparative cross-sectional study. Place and Duration of Study: Department of Dermatology, Pak Emirates Military Hospital, Rawalpindi Pakistan from Apr to Oct 2021. Methodology: A total of 175 patients with psoriasis, aged 1 to 60 years, of either gender were included. Patients were divided into pediatric and adult Groups. In all patients, gender involved, family history, trigger factors, and sites involved at onset were noted. Results: Our study reported that the majority of the respondents in the Adult Onset Psoriasis Patients Group and the Pediatric Onset Psoriasis patients (Adult Onset Psoriasis Patients) Group were males, and their percentages were 63.85% and 60.0%, respectively. In the POPPs Group, the scalp (48.89%), elbows (35.56%), and knees (11.11%) were most commonly involved at onset, similar to the AOPPs Group, where also the scalp (48.46%), elbows (22.31%) and the knees (18.46%) were the top three sites involved at the onset. In the POPP Group, 55.56% of patients had a history of psoriasis in their family compared to 58.46% of the AOPP Group. In the POPP Group, 28.89% had some trigger factor compared to 26.92% of the AOPP Group. Conclusion: This study identifies key differences between pediatric-onset and adult-onset psoriasis, with scalp and elbows as common sites and knees more frequently involved in adults. Pediatric cases showed a slightly higher prevalence of trigger factors,
