Mast Cell Tumor (Mastocytoma) in Cats

Mastocytoma Treatment for Cats in San Diego

It’s important that you give the highest level of care to your pet. Cats can often develop skin masses. If you see or feel a lump under their fur, it’s important to schedule an appointment with our veterinarians in San Diego at Tierrasanta Veterinary Hospital. Our animal hospital can diagnose a mast cell tumor, also known as mastocytoma, in cats with only a few tests. 


What is Mastocytoma?

Mastocytoma is a mast cell tumor that is located in the skin. It can be inflamed, which is usually when you will notice that there is a tumor present. 

Siamese cats seem to be more susceptible to these tumors than other breeds of cats, though any cat can get them. Additionally, the average age for these tumors to develop is 10 years old, though there have been reports of cats younger than one year and as old as 18 years developing them as well.

A variety of symptoms associated with this type of tumor include:

  • Vomiting
  • Loss of appetite
  • Itchiness
  • Enlarged lymph nodes

Approximately half of mast cell tumors on a cat are found between the trunk and perineum. In some instances, they are found on the paw or around the head and neck region. If there is widespread mast cell cancer, it may also result in an enlarged spleen and/or liver.

Getting a Diagnosis in San Diego

The only way to know if your cat has a mast cell tumor is to have a biopsy done. We will start by aspirating the tumor to determine if there are mast cells in the blood. From there, a surgical tissue biopsy is done so that we can identify the grade of the cells as well as the stage of the mastocytoma. 

Depending on what the tests show, it may be necessary to take samples from bone marrow, the kidney, or from a drained lymph node. X-rays and ultrasounds may also be taken. This technology allows us to see the exact location of the tumor and how it is developing.

Scheduling an Appointment with Our Veterinary Clinic

There are various stages of a mast cell tumor, which is why you don’t want to wait long to schedule an appointment. Once we have provided the diagnosis, we can establish the right course of treatment. This can include various antihistamines as well as the possibility of surgery.

We have a lot of experience in cat care and can provide you with the answers that you need.

If you have concerns about your cat and suspect that there is a skin tumor present, make an appointment with us today at Tierrasanta Veterinary Hospital. We can provide an exam and get your cat treated properly.
