EOSINOPHILIC GRANULOMA

This condition is sometimes called a “rodent ulcer” and is a chronic inflammatory condition that affects the lips, oral mucosa, and skin of a cat.  There are several forms but the most common involves the lip area.  When on the inner thigh area, it is called an eosinophilic plaque.

The actual cause is unknown but it seems to be associated with chronic irritation, especially licking.  The lesions may be spread to other areas by constant licking that damages the skin when done to excess.

Many times lesions will be located at points where a tooth contacts the lip.

They usually start as a reddened area and progress to become a thickened ulcerated area.

The lesions may progress to a form of skin cancer.  Sometimes they may have an allergic basis and can reoccur periodically.  Lesions can become quite severe in a short period of time involving a rather large area.  Treatment may involve surgical removal and/or medical treatment.

Medical treatment involves:  long lasting cortisone injections, ointments, and/or oral medications.   Often times, treatment in some form, will require several weeks to take effect.

(   )  Give medications as directed.

(   )  Recheck in             days             (weeks).

(   )  Notify the clinic if you have questions or the condition worsens.

These lesions heal slowly---be patient.
