What are Ear Tumors?

Felines can be affected by basal cell tumors, papilloma and inflammatory polyps, but ceruminous gland adenocarcinoma are the most common form of feline ear tumor. Appearing as black or purple masses, ceruminous gland adenocarcinoma tumors commonly affected felines between the ages of three months to five years of age. Feline affected by ear tumors have display clinical signs of itchiness, foul odor, pain and discharge from the ears, which mimics the symptoms of other common feline ear conditions.

Ear tumors in cats are defined as abnormal cell growths within the structures lining or supporting the ear. An ear tumor could emerge from the outer layer of skin, the oil or earwax glands, bones, connective tissues, muscles or middle layers of the skin within a cat’s ear. 

Symptoms of Ear Tumors in Cats

The most obvious symptoms of ear tumors in cats is itching and pain of the ears. Polyps or lumps may be visible to the naked eye inside the ear canal, but can vary depending on location. These polyps may lacerate, leading to ear discharge or inner ear bleeding. Clinical signs of ear tumors in cats pet owners may note at home include the following: 

  • Deafness
  • Ear draining from an internal abscess
  • Swelling 
  • Ear scratching 
  • Head shaking 
  • Foul odor coming from the ear 
  • Ear discharge 
  • Bloody ears
  • Pus-filled ears 
  • Waxy buildup inside the ears

If the inner or middle ear is affected by an ear tumor, the feline may display neurological signs such as a head tilt and lose her coordination, or sense of balance. 

Causes of Ear Tumors in Cats

The exact cause of ear tumors in cats is unknown, however, these tumors are believed to be the result of long-term ear canal inflammation caused by chronic infection. It is thought that this chronic inflammation may lead to abnormal development and growth of the ear tissues, causing a tumor to form. This theory comes from the fact that episodes of inflammation cause the earwax gland to promote thick secretions in the external ear canal, which may stimulate cancerous cell production. 

Felines that have a history of chronic ear infections of yeast, bacteria or mites are at higher risk for developing an ear tumor. These infections lead to increased inflammation, causing an overgrowth of tissues and possible formation of cancerous growths.

Diagnosis of Ear Tumors in Cats

Your veterinarian will likely rely his/her definitive diagnosis upon microscopic tissue examination. Termed histopathology, a microscopic examination of the tissues will provide an accurate diagnosis to the nature of the feline ear tumor. The veterinarian or specialist will need to take a small sample of tissues from the tumor and send the specimens to a specialized diagnostic laboratory. Once at the lab, a veterinary pathologist will determine the nature of the cells, which will indicate whether or not the mass can be fully removed. 

Once the laboratory results are received, the veterinarian will want to perform a urinalysis and blood work to obtain an idea of the feline’s overall health status. Radiographs are also likely completed to locate the spreading of ear tumor cells and aid the doctor in determining a treatment plan.

Treatment of Ear Tumors in Cats

Your veterinarian will likely refer your feline to a board-certified surgical specialist. A veterinary surgeon is often recommended when handling feline ear tumors, canal tumors, and masses of the middle ear. The most common and effective way of treating ear tumors in cats is surgically removing the growth. However, in cases which the tumor has grown to surrounding tissues and the tumor alone cannot be removed without damaging the ear, extensive surgery is required to ablate the canal. Depending on your feline’s specific condition and the medical advancements available to you, laser surgery to remove the mass is also highly effective.

Recovery of Ear Tumors in Cats

After surgery, you will be required to keep the surgical site clean and prevent your cat from interfering with healing time. Scratching or rubbing of the ears can cause the operation site to bleed or become infected, ulcerated, and inflamed, therefore, an Elizabethan collar will likely be sent home with you. Any manipulation of the site can remove sutures, which should be reported to your veterinarian immediately. Talk to your veterinarian if you have any questions about aftercare for your feline following surgery. 

In most ear tumor cases, surgical removal of the tumor results in complete cure. A histopathology of the mass will give your veterinarian an idea of how your cat’s growth will behave, but the veterinary pathologist will state a prognosis of recurrence.

Nothing at present

My 6 year old rescue cat has been diagnosed with malignant ceruminious cell tumours of the ears. This was diagnosed by just using an instrument in the ears. She already has major surgery last year for abdominal hernia and I do not think it is appropriate to put her through anything else. The vet is going to monitor her . She is fine in herself eating and drinking and playing. Is it that these tumours will just grow and stop her hearing.?? I understand that these do not appear anywhere else. What sort of time span are we looking at a, do they grow fast?

Thank you.

These specific types of tumours occur only the in ears as ceruminous glands are responsible for ear wax production; the tumours do spread quickly and are invasive locally. Surgery is the treatment of choice and is normally followed up by radiation therapy in some cases; I have little statistical information on life expectancy without surgery, but survivability was 75% after one year in cats which had surgical excision of the tumour.

Each case is individual and possibly your new Veterinarian doesn’t see the benefits of performing surgery but this should be ideally explained to your if this is the case; I cannot speak for other Veterinarians and their actions but it is important that we inform owners of options and why some options are not suitable to prevent your concern that you have now. I would suggest getting a second hands on opinion to see what their thoughts are. Regards Dr Callum Turner DVM

20 days of clavamix, 20 days of baytryl

My nine-year-old manx has been being treated for an ear infection for 45 days. I am beginning to suspect a polyp or a tumor as though she seems better in that she doesn't have the loss of balance anymore she still has a head tilt to the side of infected ear.Is hiding and sleeping a lot . She is still eating and drinking although I am coaxing with some special Foods. She has been on two rounds of Clavamox. At this point the vet said he could see the eardrum and thought the infection had pretty much cleared up and so put her on ear drops after 4 days of ear drops her ear started bleeding. I took her back and they put her o 20 days of Baytril. I noticed what I thought was a lump under the front of her ear and pointed it out to the vet at last visit.

Without being able to perform an examination it is difficult to say what is going on; a tumour, infection, trauma, liver disease and poisoning may all cause head tilt so it is important to determine that the underlying cause of the head tilt is the infection (there may still be some infection present in the inner ear). If you are noticing a lump near the ear, it would be best to have that checked out as well to be on the safe side. Regards Dr Callum Turner DVM
