Vincent angina: This is trench mouth, a progressive painful infection with ulceration, swelling and sloughing off of dead tissue from the mouth and throat due to the spread of infection from the gums.
Certain germs (including fusiform bacteria and spirochetes) are thought to be involved. Vincent's angina is best treated with the antibiotic penicillin.
This condition is also called Vincent (or Vincent's) angina after the French physician Henri Vincent (1862-1950). The word "angina" comes from the Latin "angere" meaning "to choke or throttle."
As with most poorly understood diseases, Vincent angina goes by many other names including acute necrotizing ulcerative gingivitis (ANUG), acute membranous gingivitis, fusospirillary gingivitis, fusospirillosis, fusospirochetal gingivitis, necrotizing gingivitis, phagedenic gingivitis, ulcerative gingivitis, Vincent stomatitis, Vincent gingivitis, and Vincent infection.
