Background: Pityriasis alba (PA) is a common, benign skin disorder occurring predominantly in children and adolescents. It is characterized by the presence of multiple, ill-defined, hypopigmented patches with fine scaling particularly over the face. Aims and objectives: To study the clinical characteristics and epidemiologic parameters in the context of current scenario in a rural tertiary care hospital in central India. Materials and methods: We conducted a descriptive observational study over a period of 1 year. We studied 100 clinically diagnosed patients with PA of the age group 2 to 15 years during this study. Results: Most common age group of patients observed was 6 to 10 years. About 87% patients had Fitzpatrick skin type IV followed by type III (7%) and type V (6%). Male to female ratio was 1.17:1. Maximum patients belonged to class III (50%) followed by class IV (37%) and class V (10%) according to the modified Kuppuswamy socioeconomic status scale (2018). Maximum patients had age of onset ranging from 6 to 10 years. Clinical characteristics revealed that maximum patients had 0 to 5 patches, with a duration of 1 to 2 months most commonly over cheeks. Associated features such as itching, scaling, and erythema were present in 18%, 98%, and 1% of the patients, respectively. Pallor was observed in 28% patients. However, significant history of atopy was elucidated in only 21% of patients. Around 6% patients showed positive family history of having PA and 14% having a positive history of atopy in first-degree family members. Conclusion: Due to the easily visible hypopigmented patches most commonly over face, PA is a common cause of concern in pediatric age group. In recent times, possibility of multiple factors other than atopy should be kept in mind while thinking of the associating or implicating factors which will lead to proper management of this pigmentary disorder.
