These findings were considered a new thought that might support a new hypothesis regarding the pathogenesis of vitiligo. Objective: In order to do further work on hypothesis which is in favor that pityriasis alba might progress into vitiligo, so the present research including clinical and histopathological study to confirm that pityriasis alba might progress to vitiligo. Patients and method: This is a descriptive clinical and histopathological comparative study carried out in Department of Dermatology, Baghdad Teaching Hospital during the period from January 2015 to August 2016. Thirty eight patients with pityriasis alba (group A) and twenty eight patients with vitiligo stage I (group B) and twelve patients with both pityriasis alba and vitiligo (group C) were included in this study. All patients were fully interviewed and full history was taken from all the patients. Also careful asking about personal and family history of vitiligo was taken. Blunt trauma was done to induce Koebner’s phenomenon. Punch biopsies were taken from skin lesion of all patients and ten biopsies from 10 persons were taken from normal skin. Each biopsy specimen was processed and stained with Hematoxylin-eosin (H & E) and Fontana-Masson (FM) for histological evaluations. Results: Clinical study-Group A: Pityriasis alba patients: The mean of age of patients in pityriasis alba ± SD was 8.68 ± 5.94 years including 33 (86.84%) males and 5 (13.16%) females.
