V sign in dermatomyositis

Abstract

V sign is a patchy or discrete macular erythema over the sun-exposed parts of the anterior neck and upper chest in patients with dermatomyositis (DM). It is one of the clinical hallmarks of DM and aids in diagnosis. It can be associated with telangiectasias and a shawl sign, which is a similar rash in the upper back, posterior neck, and shoulders.
