Abstract

Pityriasis rubra pilaris (PRP) is a rare papulosquamous skin disease characterized by palmoplantar keratoderma, erythroderma, orange plaques amidst normal skin and nail changes. A severe case of PRP can mimic erythrodermic psoriasis; therefore, accurate diagnosis is challenging. Clinical presentation, dermoscopic findings, and skin biopsy play pivotal roles in differentiating PRP from psoriasis. We present a case report and review the literature about the imperative diagnostic clues to distinguish PRP from psoriasis.
