Postsurgical Appearance of Chilblains Lupus Erythematosus

Abstract

Chilblain lupus erythematosus is a rare form of chronic cutaneous lupus erythematosus that presents as pruritic and painful cutaneous lesions. The lesions follow a relapsing and remitting pattern and are often located on the dorsal surfaces of the hands or feet. Its treatment is supportive in nature, and the lesions often recur. In this case report, we describe the course of a patient, with no history of any form of lupus, who developed chilblains lupus localized over the incision site after undergoing hand surgery. We discuss the differential and incorrect diagnoses made before determining the proper diagnosis of chilblains.
