Perianal Adenoma

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

                      General Information



Perianal adenomas arise from the numerous small glands present in

the anal area.  They are one of the most common tumors in male

dogs over 8 years of age.  Occasionally they develop in younger

dogs.  Females are rarely affected.  Generally the tumor is an

easily observable lump under the skin close to the anus or on the

underside of the tail.  Multiple tumors may be present.  Raw,

bleeding areas on these tumors are common.  Malignant growths

that spread or grow progressively deeper occur occasionally.



                 Important Points in Treatment



1.  Surgical removal of the tumor is the best treatment.

    Removal of the testicles (castration) at the same time is

    advised, since this may arrest tumor growth.



2.  Female hormones are used when the tumor is inoperable and

    also as supplemental treatment after surgical removal.



3.  Radiation treatment may be necessary in deep, widely spread

    or multiple inoperable growths.



4.  Medication:  The medication must be given as directed.

    Notify the doctor if you cannot do so.



5.  Diet:  Ordinarily no special diet is required.



6.  Elimination:  Make sure your pet is having normal bowel

    movements.  Report any abnormalities to the doctor.



7.  Environment:  Your pet should be kept in the house on

    frequently changed bedding during the healing period.



8.  Surgical patients:



    * Check the incision at least twice daily to make sure it has not

    been contaminated with stool.



    * Please call the doctor if your pet chews at the incision,

    scoots along the floor or otherwise irritates the incision.



    * Your pet will be evaluated for suture removal in ____ days.



       Notify the Doctor if Any of the Following Occur:



    * There is excessive drainage or bleeding from the incision.



    * Your pet strains to have bowel movements.



    * Your pet's tumors return after removal.



    * Your pet chews the sutures or otherwise opens the incision.



    * Your pet's general health changes.
