Case report: Leprosy and psoriasis: A rare coexistence

Abstract

Leprosy presents with erythematous or pigmented patches, plaques, and nodules with loss of sensation and nerve thickening. Psoriasis presents as sharply demarcated erythematous plaques with overlying silvery scales. The controversial relationship between both has existed since biblical times when psoriasis was considered to be a form of leprosy. Records of leprosy patients have depicted a rarity of the coexistence of psoriasis, leading to a hypothesis that both rarely develop in the same patient. We report a rare coexistence of both diseases.
