    Psoriasis classically presents with chronic sharply demarcated erythematous papules and plaques with a silver scale, presenting bimodally in ages 20-30 and 50-60. Patients may also have pitting of the nails and involvement of the intertriginous spaces and ear canal. The plaques are typically asymptomatic but may be pruritic. Psoriasis also has many atypical presentations.
