Chest of a girl with well marked erythema circinatum

Watercolour drawing of the chest of a girl, showing well marked erythema circinatum. The circinate patches first appeared on the abdomen, where they varied in size from a threepenny-piece to a half-crown. Two days after the appearance of the isolated spots they coalesced to form a large patch, which extended like a great yellow stain over the abdomen and chest.
