Eponym: the Lemierre syndrome.

Fig. 1 Dr. Andre Lemierre Lemierre syndrome, also known as postanginal sepsis, is a severe complication of an acute oropharyngeal infection that results in septic thrombophlebitis of the ipsilateral internal jugular vein with subsequent septicemia, often complicated by metastatic infections. The usual agent in Lemierre syndrome is Fusobacterium necrophorum, a commensal bacillus of the oral cavity. After the advent of antibiotic therapy, especially in the 1960s and 1970s, when penicillin was frequently used to treat pharyngeal infections, Lemierre syndrome was often referred to as the "forgotten disease". Today with increasing antibiotic-resistant organisms and decreasing awareness of the syndrome, subsequent reemergence of this syndrome is becoming more common in clinical settings. The syndrome starts initially as an acute oropharyngeal infection followed by septicemia with intense fevers, rigors, swelling, and tenderness on the lateral aspect of the neck, parallel to the sternomastoid muscle (septic internal jugular vein thrombophlebitis), and multiple metastatic infections.
