Other similar injuries

Canker sores are very frequent lesions that 80% of the population has had or will have at some time in their lives, often on a recurring basis. However, there are other alterations that have a similar presentation with which they can be confused. Two of them are the following:

However, herpes and thrush differ in what produces them: herpes is produced by a virus, being contagious and can also appear in other areas of the face other than the mouth. In the case of canker sores, the lesion is limited to the oral area and since they are not due to viruses they do not cause contagion.

2. Syphilitic chancre
