title: Lemierre's syndrome: Porphyromonas asaccharolytica as a putative pathogen.
abstract: A case of Lemierre's syndrome is reported in which metastatic abscesses resulted from septic thrombophlebitis of the internal jugular vein secondary to bacterial pharyngitis. A 32-year-old male suffering from a painful left-sided neck mass, sore throat, and fever was admitted to our hospital. Computed tomography revealed thrombosis of the left internal jugular vein, septic pulmonary emboli, and a liver abscess. Blood culture showed Porphyromonas asaccharolytica. Although empyema occurred transiently during the treatment, the patient recovered following prolonged antimicrobial therapy. Although Fusobacterium species are a well-known cause of Lemierre's syndrome, cases in whom Porphyromonas species was isolated have scarcely been reported. Moreover, case reports from Japan have been few.
