E-mail: [email protected] 1 A 2-year-old boy was referred to the paediatric ward because of an itchy annular rash on the trunk and extremities. Up to referral he had been suffering from a streptococcal tonsillitis, which had been treated with Cefoxitin, 30 mg/kg body weight a day for 7 days. At the admission, there was noted an annular, generalized rash with central pallor (Figs. 1 and 2) and a discrete oedema of the feet, which had resulted in walking impairment for one day. He was afebrile and the capillary C-reactive protein was 1.74 mg/dl (normal range < 0.5 mg/dl). What is the diagnosis? See next page for answer- Fig. 1. Back of a 2-year-old boy.
