Eyelid Tumors

                         -------------

                      General Information



Eyelid tumors are growths on the eyelids.  The cause is not well

understood.  False tumors (pseudotumors) caused by inflammation

may also occur.



Tumors are divided into 2 groups:  benign (non-cancerous) and

malignant (cancerous).  Most eyelid tumors are benign;  however,

it may be difficult to distinguish between the 2 types unless the

tissue is examined microscopically.



Eyelid tumors that grow on the inner aspect of the eyelid may rub

against the eyeball and cause pain and damage to the eye.  Some

tumors become raw and infected.  Eyelid tumors may grow near or

in the tear ducts and block tear flow.



Any eyelid tumor should be removed.  Eyelid tumors may grow so

much that a large section of eyelid tissue must be removed to

help ensure that the entire tumor is eliminated.  In those cases,

eyelid reconstruction (plastic surgery) must be done to retain

proper eyelid function.  Removal of the tumor in the early stages

of growth often avoids the need for such extensive surgery and

decreases the overall risks to your pet.



                 Important Points in Treatment



1.  Methods used for eyelid tumor removal include excision

    (surgical removal), cryotherapy (freezing) and electrosurgery

    (use of electric current).



2.  Most cases require a general anesthetic and brief

    hospitalization.



3.  Laboratory tests may be needed before surgery.



       Notify the Doctor if Any of the Following Occur:



    * The tumor re-appears.



    * Your pet repeatedly rubs its eye.



    * The eye is red or watery.
