Case presentation

A 10-year-old girl presents with an asymptomatic, reticulated, erythematous rash on the medial aspects of her thighs and lower legs of one-week duration (Figure 1). Her parents report that the rash appears worse when she has been outside or running around. The girl is otherwise well and does not have a history of any skin diseases. 

On questioning, the parents say that the girl had mild coryzal symptoms approximately two weeks earlier and they recall transient facial erythema. She was not febrile at any stage.
