Lemierre's Syndrome with a Palmar Lesion.

Lemierre's syndrome can be fatal if diagnosed late or not treated appropriately. We herein report a 40-year-old woman with a fever and pain with tenderness in her palms after the administration of antibiotics for pharyngotonsillitis. She was diagnosed with Lemierre's syndrome, and her symptoms improved after the administration of intravenous ampicillin-sulbactam. In this case, the palmar lesions indicated septic emboli and were an important finding in recognizing Lemierre's syndrome. Lemierre's syndrome should be considered in the differential diagnosis of patients with a persistent fever following oropharyngeal infection, even if they have received antimicrobial therapy, resolved pharyngeal symptoms, and negative culture results.
