What are Eyelid Tumors?
A mass on the eyelid of your dog can be benign or malignant and can result for reasons such as gland issues or breed predisposition. A growth on the eyelid should be evaluated by a veterinary professional without delay; pain or vision inhibition can occur, causing distress for your companion.
Eyelid tumors in dogs are very common, especially in older dogs. The majority of these eyelid tumors are non-cancerous, but there are some tumors that are cancerous. Eyelid tumors many times occur on the glands that line the eyelid margins. These tumors generally do not cause your dog any problems, they are cosmetic. However, if the tumors become an irritation to your dog, the tumors may be removed.
Symptoms of Eyelid Tumors in Dogs
If you notice a growth on your dog’s eyelid, have it checked out by your veterinarian. These eyelid tumors many times appear on the edge of the eyelid. They can vary in size, but all need to be thoroughly checked out by your veterinarian. You may not be able to clearly see a growth on the eyelid if it is very small so there are other symptoms to watch for.
- Presence of a mass on the eyelid
- Abnormal protrusion of the eyeball
- Eyelid swelling
- Conjunctiva swelling
- Eye misalignment or cross-eye
- Inflamed cornea
- Rubbing the eye
Causes of Eyelid Tumors in Dogs
There is not a particular reason as to why a dog develops eyelid tumors, nor is there a reason why some of these tumors are benign and some are cancerous. Trauma could play a part in the development of an eyelid tumor.
Genetics may play a role in the formation of eyelid tumors; there are some breeds that are more prone to eyelid tumors. Those breeds include the Dachshund, Bloodhound, Cocker Spaniel and Bulldog.
The various glands in the eyelid margin can develop tumors. The meibomian gland is one of the more common glands that a tumor will develop. If the meibomian gland ruptures, a cyst can form on the inside of the eyelid. These cysts, while not technically tumors, may need to be surgically removed to avoid causing unnecessary irritation to the eye.
Diagnosis of Eyelid Tumors in Dogs
It can be difficult to properly diagnose an eyelid tumor as benign or cancerous without taking a biopsy or tissue sample of the tumor. Sampling procedures that may be required to get an appropriate tissue sample are:
- Needle aspiration
- Punch biopsy
- Smears
- Full excision
Once the sample has been collected, it is viewed under a microscope to diagnose the type of tumor. Your veterinarian will not be the one examining the sample. A veterinary pathologist will examine the sample and send a report with their finding to your veterinarian. Once the tumor has been diagnosed, the proper treatment plan can be put in place.
If the entire mass was removed, it is the veterinary pathologist’s job to determine if the tumor is cancerous and if all the cancer has been removed.
Treatment of Eyelid Tumors in Dogs
The removal of an eyelid tumor can be done using two different techniques.
Cryotherapy
This procedure involves using a local anesthetic and removing as much of the tumor as possible. Then, Cryotherapy is used to freeze the site of the tumor to kill any of the tumor cells that were left behind. Cryotherapy may need to be repeated if the tumor continues to grow.
Surgical Removal
This procedure involves anesthetizing and then removing a wedge of tissue, including the tumor, and then suturing the lid closed. By removing the surrounding tissue along with the tumor, it is hoped that all the tumor’s cells are also removed. This procedure is especially used for large tumors. Any surgical procedure involving the eye is very complex. Your veterinarian may decide to refer you to a specialized canine ophthalmologist.
Recovery of Eyelid Tumors in Dogs
Dogs that are recovering from surgery must follow doctor’s orders. Many times that means wearing a cone or Elizabethan collar to prevent your dog from rubbing their eye and causing harm to the affected eyelid.
Keep your veterinarian informed of any increase in swelling, loss of stitches, bleeding or drainage from the eyelid. Follow-up care may include antibiotic ointments or drops as well as anti-inflammatory medications. Always follow directions for any medication given and follow-up with your post-surgery appointments.
Eyelid Tumors Questions and Advice from Veterinary Professionals
Has Symptoms
my 9 yr old female ridgeback mix is about 55 pounds and has recently developed a growth on her right eye lower outside corner eyelid underside and I am concerned of the cost of treating it . she is active healthy and walks plenty everyday and only has dog food and maintains an active lifestyle. iam not sure if its a clogged tear duct or some other issue
3318 Recommendations
Blocked tear ducts occur around the inner corner (medial canthus) of the eye; there are various masses which may occur which may be benign or malignant in nature, without examining Abby I couldn’t give you an indication of treatment and your location and Veterinarian would vary the cost (back-end prices vary widely even between Veterinarians within the same city). To get a better sense of cost for ‘mass removal’ in your area call your Veterinarian for a ballpark figure. Regards Dr Callum Turner DVM

My Maltese cross has a lump on her upper eyelid which was treated at first with antibiotic ointment. Has gone down, the vet took a swab and said it was a melanoma. It's not bothering her, and was booked in for surgery which had to be cancelled at the last minute as staff shortage. What I want to know should I get a 2nd opinion has I have been reading that it is a big op and if it is not necessary I don't want to put her through that

My English Labrador will be 8 years old this month. I recently noticed on the lower left lid rim 2 tiny bumps. She doesn't have any mattering, nor rubs it. As far as I can tell, she isn't experiencing any dis-comfort. She has always been healthy, no medications, no other concerns except keeping her weight under control. At this point, should I take Sadie to see her regular Veterinarian or find a Canine Ophthalmologist to do an eval or remove it? What makes the most sense financially for me?
3318 Recommendations
Two small bumps on the rim of the lower eyelid are probably meibomian gland adenomas which are usually nothing to be worried about; but confirm this with your regular Veterinarian. Surgery is only required if they get too large, cause irritation to the eye, bleed or ulcerate. Your regular Veterinarian would be able to remove these quite easily or to freeze them off. Regards Dr Callum Turner DVM

My dog has a big blueberry sized bump on her right upper eyelid that showed up randomly. Is this something common that I can just watch for a few days? Is there any recommended home treatments for random skin lumps?
3318 Recommendations
There are various types of eyelid tumours which vary in severity from benign to malignant; I would recommend having your Veterinarian take a look to be on the safe side. Meibomian gland tumours are quite common making up over half of eyelid tumours; melanoma, histiocytoma, mastocytoma and papilloma are all other possible eyelid masses. I would strongly suggest having your Veterinarian take a look to be on the safe side. There is no at home treatment, just keep an eye on the mass and make sure that it doesn’t get scratched or damaged. Regards Dr Callum Turner DVM
HI, MY DACHSHUN HAS A LUMP ON THE EYELID. IT ALSO APPEARRED OUT OF NOWHERE. THE DOCTOR SAID IT IS MOST LIKELY NOT CANCEROUS BUT NOT SURE. IT IS ON THE CONJUNCTIVA NOT THE EYELID AND HE SAID EVEN IF REMOVED IT MIGHT GROW BACK. CAN SOMEONE PLEASE TELL ME IF THYMEX FROM STANDARD PROCESS MIGHT HELP IN THIS CASE?
Can you let me know where you purchased the thymes?thank you
My dog had a similiar mass on her upper eyelid and was tested by a needle aspiration that diagnosed her with spindle cell sarcoma. I read about another case with the same diagnosis and giving the dog a supplement called Thymex from Standard Process. I decided to go that route and also cook my dogs food and after 3 months the mass disappeared. I went back to the vet and they couldn't believe the mass was gone. It's been 3 years and my dogs eyes are very healthy.

I have a 12 year old cocker spaniel who seemed to develop an lump on right eyelid almost overnight. Took her to vet who aspirated lump, looked at fluid under microscope, said he didn't see any cancerous cells, but couldn't rule out. Put my dog on antibiotics, which has helped some, but few days after the 7-day antibiotic meds ran out, it's full blown again. Reading responses via this website, learned about a product - Thymex from Standard Process - is this safe for canines, and if so, where can one obtain? This is very concerning to me and do have her scheduled for follow-up on Monday. Please advise. Want to do what's best for her, but unsure at this point what that really is...

Hi, my 11 year old shih tzu bichon cross got a lump on his left eyelid a while back. But he does have cysts on his body and I figured it would burst like the ones on his back. But it has started bleeding and now it is bothering him and hes scratching his eye now.

I have a 7 yr old YorkieBi
chon male dog. Right before Christmas he developed a lump on his lower right center of his eyelid. It came on quickly and we took him to the vet. The dog was prescribed Neomycin and Polymyxin B drops. At first the lump got smaller but then started to grow back to the size of a small blueberry. When we went back to the vet for a follow up, he referred us to an eye specialist for dogs. He could not answer any questions concerning the lump/tumor. What type of lump/tumor would come on suddenly, respond to medicine briefly and then grow back? The dog is acting normal and is not trying to itch it.

My 15 year lab has had a tumor on her upper eyelid for the past couple years and it has been a watch and wait situation as it was small and not growing. But the past several months it has started to grow quite large and while the vet says it isn’t scratching her cornea, and that due to her advanced age we should leave it, I worry that it is getting too large and it bleeds from time to time. Is there a less invasive remedy to help keep it clean or shrink it other than surgery?
