Indolent Ulcer in Cats

Feline indolent ulcers, also known as rodent ulcers or eosinophilic ulcers, are common dermatological conditions affecting cats. Only a few authors have reported the condition in dogs (Kim et al. 2010). It is a condition included among Eosinophilic Granuloma Complex which also includes two other forms, the eosinophilic plaque and eosinophilic granuloma. Manning et al. (1987) has reported the coexistence of all the three forms in one animal. The presentation of lesions are either unilateral or bilaterally symmetrical or asymmetrical and usually occur on the upper lip close to the philtrum. They also appear on other parts of the body. The ulcers are painless, non-pruritic and usually associated with submandibular lymphadenopathy. They are depressed, reddish, circumscribed lesions with raised borders. In some cases, ulcers are preceded by swollen lips.
