A 2-MONTH-OLD infant, born by spontaneous vaginal delivery, was admitted for treatment of cellulitis of 1 toe as a result of a hair tourniquet. He was 3 kg at birth after a full-term pregnancy. His mother was aged 26 years, gravida 2, para 1, aborta 0 and had a seizure disorder for which she received divalproex sodium daily. She had learning disabilities and required special education. The infant's father, aged 60 years, is healthy. The infant was observed in the hospital for 1 week for an irregular heartbeat. He was well until he was admitted for treatment of cellulitis. Findings from physical examination revealed cutaneous lesions (Figure 1). He had a single café-au-lait lesion on his left arm. A cerebral magnetic resonance imaging scan (Figure 2 and Figure 3) and an echocardiogram (Figure 4) were obtained. The cellulitis resolved after administration of antibiotic therapy, and he was discharged. At age 6 months, he developed infantile spasms.
