RESUMO
BACKGROUND: A depressed host defense is a major contributor to the oral shedding of herpes simplex virus (HSV) type 1. Here, we present an instance in which herpes simplex labialis was reactivated following major spinal deformity surgery. CASE DESCRIPTION: A 59-year-old female underwent spinal deformity correction for lumbar degenerative scoliosis. On postoperative days 2-3, she presented with pyrexia (38°C) and tachycardia (94/min); by day 5 she had multiple ulcers around her lips and was HSV IgG positive. She had a remote history of herpes simplex I infection 7 years previously. Once started on oral acyclovir, the lesions improved, and by day 15 postoperative, her pyrexia and all lesions completely resolved. CONCLUSION: HSV-1 should be suspected in patients with a previous history of HSV and postoperative pyrexia. Adequate prophylactic administration of acyclovir should result in resolution of these outbreaks, in this case, attributed to overly extensive spinal deformity surgery.
