Dog Myxosarcoma

These soft tissue tumors are fibroblast origin. They are very rare and appear in middle-aged to senior dogs. They can arise in any part of the dog’s body but are more common on their skin and directly under their skin. Most of the myxosarcomas are located in a dog’s limbs and chest. There are however, occurrences in the brain, eye and heart. They make up about fifteen percent of subcutaneous and skin tumors in dogs. Myxosarcoma is one of many soft tissue tumors that can occur. The tumors can be benign or malignant.

Signs and Symptoms

Although these are "soft" tissue tumors, they can appear as a firm mass on the dog’s body, mouth and limbs. If the tumor occurs in the intestinal tract your dog can have Dog Vomiting and Dog Diarrhea which ultimately leads to Dog Weight Loss. If they appear in the mouth, your dog will have a Dog Loss of Appetite, problems swallowing and Dog Bad Breath. Any soft tissue tumor can also appear in the nerves and can cause lameness, pain and other neurological symptoms.


An accurate history is vitally important as a contribution to proper diagnosis. By gathering all of the possible information such as origin, site, level of the tumors' aggressiveness and determine if it is malignant, whether or not it has metastasized. These items can be acquired by blood tests, x-rays, advanced imaging such as CT and MRI or ultrasound. It is also helpful to do fine needle aspiration of the mass.

Treatment Options

Treatment modalities include Dog Cancer Chemotherapy, Dog Radiation Therapy and surgery. The combination of surgery and radiation will attack the point of origin. If chemotherapy is included it is possible to slow down the metastasis of those that have been known to be aggressive.


Depending on the level of the cancer, the prognosis is guarded. If it is treated at an early stage, the prognosis is good. The sooner it is detected the better the result.

Home care

Any cancer will cause Dog Pain and loss of appetite. It is important to maintain a healthy weight and control your dog’s pain. Your veterinarian will prescribe pain medication for your dog. It is a good idea to prevent severe pain. It is much harder to ease the pain than it is to prevent it.
