A Case of Extensive Pityriasis Alba

Hypopigmented

INTRODUCTION

Pityriasis alba (PA) is a common disease, usually seen in children. The lesions are frequently limited to the face, but the neck, arms, and shoulders can also be involved. Initially the typical lesion consists of an irregular, round or oval, pink patch, some­times with an elevated, and slightly erythematous border, varying in size from a few millimeters to a few centimeters. After a few weeks, the erythema usually fades, leaving a whitish macule covered by fine scales. Atypical forms of PA are the extensive and pigmenting types. Extensive PA is characterized by typical PA lesions distributed in a generalized fashion. We present a case of extensive PA, which has not yet been reported in Korean literature. viagra jelly
