Aim: Methodological variations, geographical factors, and ethnic differences contribute to the wide variability in the prevalence of psoriasis. There are limited studies on the prevalence of psoriasis in Türkiye, and no similar study has been conducted in our region. This study aimed to assess the frequency of psoriasis in Antalya. Materials and Methods: This single-center, descriptive study included healthy adult volunteers over 18 years old accompanying patients at internal medicine outpatient clinics in Akdeniz University, Antalya, Türkiye. We aimed to recruit 1000 participants for this study by utilizing the quota sampling method. Results: Of the 1075 participants, 980 (age range, 18-83; mean ± standard deviation, 45.90±14.00) agreed to participate in the study. Among the 27 suspected cases, 19 were confirmed to be psoriasis (12 females and 7 males). There were 9 new cases diagnosed. Psoriasis prevalence was 1.93 per 100 [confidence interval (1.2-2.9)]. Plaque psoriasis was present in the majority (94.7%) of diagnosed patients. The smoking rate was 42.1%. The body surface area was ≤ 10% in all patients. 94.7% of patients had the Psoriasis Area Severity Index values ≤ 10. 44.4% had a family history of psoriasis. Disease severity was lower than that in our center’s previous registry survey. Conclusion: The frequency observed in our study was found to be higher than that reported in both Turkish studies and global studies. Diagnosed patients had mild psoriasis. Quota sampling is appropriate for estimating rare dermatological conditions in patients’ relatives or companions. This screening approach allows for the cost-effective collection of data in a shorter period, with a reduced workforce.
