It is named after Jean Hyacinthe Vincent, a French physician who was working at the Paris Pasteur Institute.
The ulcers appear surrounded by reddened area and they bleed when touched or when the pseudo membrane is removed.

[4] Different types of Vincent's angina were sometimes defined, such as pseudomembraneous,[8] or acute / subacute / chronic / recurrent.
