Pityriasis Alba


Pityriasis Alba (more commonly, PA) refers to a rather common skin disorder, found mostly among children and young adults, characterized as dry, undefined, scaly, and faint patches on the face (called pityriasis), upper arms, shoulders and/or neck, that caves in to leave hypo-pigmentation behind. These round patches of 0.5-2 cm could advance to three clinical stages of Papular Erythemtous, Papular Hypochromic and Smooth Hympochromic, where ‘papular’ denotes scaling. The patches could last from a month to maybe an year long; the face patches particularly last a year. Being a self-limiting skin condition, it normally requires moisturizing cream to be applied upon.
