Later in 1904, Vincent described the same pathogenic organisms in "ulceronecrotic gingivitis ". As a result, Vincent's angina is widely confused with ...

Lemierre's syndrome begins with an infection of the head and neck region, with most primary sources of infection in the palatine tonsils and peritonsillar tissue.
