Drug Reaction, Eosinophilia, and Systemic Symptoms (DRESS) Syndrome As a Mimicker of Spinal Infection: Awareness for Spinal Surgeons.

Drug reaction, eosinophilia, and systemic symptoms (DRESS) syndrome is a delayed severe drug hypersensitivity (type IVb) syndrome with cutaneous eruption, hematological abnormalities, and multi-organ involvement. The wide spectrum of the disease manifestations, long-term sequelae, and high mortality rates are a clinical concern. Though not commonly reported in spinal surgery patients, the use of long-term antibiotics is a potential causative agent in spinal infections. DRESS syndrome can mimic systemic spinal infections, and clinical diagnosis requires high awareness and extreme vigilance. Prompt recognition and appropriate action can mitigate the potential poor outcomes and improve patient prognosis.
