A 26-day-old male neonate presented with a 3-day history of low-grade fever (maximum 38.5°C), increased irritability, decreased oral intake and skin eruptions. The patient was born at 39 weeks’ gestation following an uncomplicated pregnancy and spontaneous vaginal delivery, weighing 3.7 kg. The neonatal period was unremarkable until presentation. On examination, vital signs included temperature of 38.2°C, heart rate of 145 beats per minute, respiratory rate of 42 breaths per minute and oxygen saturation of 98% on room air. The infant appeared alert but irritable. Cardiovascular, respiratory, abdominal and neurological examinations were within normal limits. The striking skin findings consisted of multiple well-demarcated, annular erythematous lesions with central clearing distributed over bilateral lower extremities ( figure 1). Individual lesions demonstrated mildly raised erythematous borders with central dusky discolouration, displaying a polycyclic configuration without mucosal involvement or vesicle formation. Parents also reported lesional migration and morphological changes over approximately 12 hours. Laboratory studies revealed white cell count of 8.2 × 109/L with normal differential, haemoglobin 142 g/L, platelets 285 × 109/L and C-reactive protein mildly elevated at 15 mg/L. Blood and urine cultures were obtained. Given the clinical presentation of fever and rash in a neonate, empirical antibiotic therapy was initiated pending culture results.
