Objective: Pityriasis alba is mostly seen in individuals with a history of atopy, although it may occur in non-atopic individuals. Despite many hypothesis, no certain etiologic factor for pitryriasis alba has been determined. We aimed to investigate the roles of environmental factors, inhalant and food allergy sensitization in its etiopathogenesis. Methods: We noted patients’ and controls’ age, gender, education level of parents, xerosis, hand soap type, bathing frequency, bath water temperature, wind condition in the location, using sun screen cream, sun exposure time, results of inhalant allergen and food allergen testing. Inhalant allergy test was carried out through a skin prick test for children older than two years, and a food allergy test was carried out through prick to prick test for children of all ages. Results: The findings showed that there were significant relationships between pityriasis alba and xerosis, inhalant allergen sensitization (p<0.0001, p=0.009, respectively). Conclusion: We conclude that xerosis and inhalant allergen sensitization are associated with pityriasis alba. Therefore, we think that clinicians should suggest moisturizers to patients with pityriasis alba and make their inhalant allergy tests in clinical follow-up of patients.
