Skin disorder characterized by small, flat, purplish, usually itchy papules, occurring most often on the wrists, forearms, and thighs.
A benign (not cancerous) skin condition consisting of shiny flat papules (small superficial bumps on the skin) that vary from pink to red to violet. The itchy bumps of lichen planus usually develop on the arms and legs but may occur anywhere on the body. Diagnosis is made through physical examination, medical history, and sometimes a skin biopsy. Treatment of the rash is with topical and, in severe cases, oral corticosteroids. Retinoids (forms of vitamin A) and phototherapy (treatment with light) have also been used.
An inflammatory rash marked by the presence of itchy, red to violet, polygon-shaped papules, which typically appear on the scalp, in the oral cavity, or on the limbs. The papules may merge into plaques crisscrossed by faint fines called “Wickham’s striae.” Typically, the rash persists for 1 to 2 years and then spontaneously improves, although about one in five patients will suffer a recurrence.
