Lemierre's syndrome: more than a historical curiosa.

Lemierre's syndrome is a severe illness caused by the anaerobic bacterium, Fusobacterium necrophorum which typically occurs in healthy teenagers and young adults. The infection originates in the throat and spreads via a septic thrombophlebitis of the tonsillar vein and internal jugular vein. The ensuing bacteraemia is complicated by septic emboli to a range of sites such as lung, joints, and bones. Although rare, there is evidence of a resurgence in the condition in recent years, possibly associated with reduced use of antibiotic therapy for sore throats. The typical clinical picture is characteristic but many clinicians are unaware of the condition and diagnosis is often delayed with potentially fatal consequences.
