Eosinophilic granulomas present in various forms (see pictures below).
- Mouth lesions Appear as raised firm ulcerated growths on the tongue and/or hard palate
- Rhodent ulcer Appear as areas of skin loss often on the lip margins adjacent to the upper canines
- Linear granuloma
Some cats get eosinophicic granulomas on their body which can be quite itchy (pruritic) and cause the cat to continuously lick them. Sometimes they are in a straight linear pattern down the back of the affected cat's hindlegs
Based on the clinical signs, a confirmation of eosinophilic granuloma is made by biopsying the lesions and having them analysed by a pathologist.
The first step is to eliminate flea and food allergy as possible causes. Step up the flea control and feed a hypoallergenic diet in case of a food allergy.
If no success it's time for a skin allergy test to determine if there is something in the environment that is causing a bad allergic reaction.
The main drugs used to treat eosinophilic granuloma are:
- Cortisone injection or tablets
For resistant cases, we use some newer drugs in combination with the cortisone
- Chlorambucil: (0.1-0.2mg/kg each 2 days)
- Cryotherapy: intramuscular injections of Aurothioglucose 1mg/kg each week until remission, then once a month
