Certain ulcerative conditions affect keratinized mucosa, whereas others are found on nonkeratinized mucosa. Oral ulcers are considered to be painful.
Erosions, sometimes mistakenly referred to as ulcerations, are shallow, craterous lesions that involve only the epithelial layer with little or no damage to the underlying connective tissue. Unlike ulcers, erosions typically do not involve a yellow fibrinous slough that covers the base of the lesion; instead, erosions may appear erythemic.
Diagnosis of an ulcer on oral examination should prompt the clinician to identify the specific etiology, immediately render therapy to eliminate the cause, and work with the owner to prevent recurrence.
The following images of erosions and ulcerations illustrate various diseases and conditions.
