Fifth Disease ( Erythema Infectiosum )
A 12 month old boy is brought to the emergency department by his mother because of a rash on his face as shown. Just over a week ago he had a cold and was febrile. His medical condition was not bad enough to seek medical advice.
The child had erythema infectiosum, a benign childhood condition characterised by a classic slapped-cheek appearance and a lacy exanthem. A symptom-free period of 7-10 days is followed by the appearance of a rash. The slapped-face appearance fades after 2-3 days and is followed by an erythematous rash on the extremities.
It is a self-limiting illness that resolves without complications in classic childhood form.
