title: A rare case of Lemierre`s syndrome caused by Porphyromonas asaccharolytica.
abstract: Lemierre's syndrome is only very rarely caused by Porphyromonas asaccharolytica. Here, we report the case of a 35-year-old man who developed a left peritonsillar abscess, thrombophlebitis of the left internal jugular vein, and septic embolization of both lungs. Anaerobic P. asaccharolytica was isolated in the blood cultures, and we subsequently confirmed the diagnosis as Lemierre's syndrome. Our case indicates that although P. asaccharolytica is not commonly found in oral cavities, this organism may still cause Lemierre's syndrome. Consequently, when it is detected in blood cultures, the treating physician should perform the medical examination while keeping in mind the possibility that the patient could have Lemierre's syndrome.
