Feline eosinophilic granuloma complex (EGC) is not a disease, but rather
a reaction to an underlying allergy. EGC actually consists of three separate
- Indolent ulcers (rodent ulcers)
- Eosinophilic plaque
- Eosinophilic granuloma
Eosinophils are a healthy cat’s weapon against parasites, but in cats
with EGC, the eosinophils react to an allergen rather than to a parasite.
The eosinophils then cause damage to the collagen in your cat’s skin
the result of which is the three conditions above. The source of your cat’s
allergy may range from food allergies, to atopy (inhaled allergies), to parasitic
allergies. Often the cause of the allergic reaction is not found and the
EGC is considered to be idiopathic. EGC seems to be a genetic trait in some
lines of domestic cats.
Symptoms of Feline Eosinophilic Granuloma
Eosinophilic granuloma, also known as linear granuloma, are often raised
and elongated. They can appear on the back of a cat’s thighs, on the
cat’s lip and chin, or on the pads of the cat’s feet. The granuloma
may come in clusters, or you may find a single granuloma. Either way, the
granulomas are often accompanied with hair loss. Frequently these lesions
ooze, and some ulcerate, especially those on the bottoms of the cat’s
feet. Granuloma on the lips may look to be nothing more than a swollen lower
lip, almost as if the cat is pouting.
Eosinophilic plaques are intensely itchy lesions that appear as thick, raw
skin. These lesions typically appear on the cat’s inner thigh, throat,
or belly. If your cat is constantly scratching at her lesions, she may be
reacting to eosinophilic plaque.
Indolent ulcers present as an erosion of the upper lip. These lesions can
spread to your cat’s tongue, so if you identify a lip ulcer, it is
best to check inside your cat’s mouth to see if the condition is there
Treatment of Feline Eosinophilic Granuloma
might recommend any of the following treatments for your cat’s EGC lesions:
Since EGC is the result of an allergy, if you can identify the source of your
cat’s allergy, it is necessary to remove the source from your cat’s
environment. Your vet may perform an intradermal skin test to see what kind
of allergies your cat has if EGC becomes a recurrent problem. If your cat suffers
from a food allergy your vet might recommend:
If you find your cat is allergic to fleas, you can use:
Occasionally indolent ulcers are precancerous, so your veterinarian might
choose to do a biopsy to rule out cancer.
