Can Canine Osteosarcoma Misdiagnosis Happen?

Question Mark

 

Possible, but it’s not likely since canine osteosarcoma can be pretty well read on an X-ray. The area in which the tumor is located, as well as its appearance, pretty much nails it. Still, there are a few other cancers that cause lytic lesions (lysis is destruction of cells by disruption of the bounding membrane, allowing the cell contents to escape) in bone that are worth noting: chondrosarcoma, squamous cell carcinoma, and synovial cell sarcoma.

 

Chondrosarcoma

Chondrosarcoma is a tumor that arises in the cartilage. It generally is seen in flat bones like the skull or the ribs, but can also occur in the limbs. While there is a possibility that chondrosarcoma is not as malignant as osteosarcoma, mainstream treatment recommendations still include amputation of the affected bone. A post surgical tissue biopsy would suggest which chemotherapy drugs would be used .

 

Squamous Cell Carinoma

Squamous cell carcinoma is most often found in the jaw or toe bones and generally not found in the same bones as an osteosarcoma. It’s found in the periosteum, a external coating or layer of the bone. While the tumor is known to spread slowly, it is very destructive. Mainstream medicine suggests amputation.

An alternative option to mainstream medicine: In Nikki’s last life, after four toes were surgically removed, he was diagnosed with squamous cell cancer in the nail bed. Knowing the diagnosis, I used a black blood root paste which I applied at home and the tumor would be expelled by the next morning, the area healed within a week to look as if nothing had ever occurred. No amputation, and no more squamous cell cancer in the treated toe ever returned.

Synovial Cell Sarcoma

Synovial Cell Sarcoma is a tumor of the joint capsule lining. It always affects both bones of the joint. Osteosarcoma, regardless of size, will not cross over to an adjacent bone.

 

Fungus Infection of the Bone

The bone infection coccidiodomycos is caused by the fungus coccidioides immitis which is native to the Lower Sonoran Life Zone of the Southwest U.S., northern Mexico, and parts of Central and South America.  Popularly called San Joaquin Valley Fever or Valley Fever, the infection is generally limited to a few calcified lymph nodes in the chest and possibly lung disease. In cases of mild respiratory infection, dogs may have a cough. If the pulmonary disease is advanced, generalized pneumonia, fever, weight loss and loss of appetite are usual. But with or without respiratory signs, spread to the appendicular skeleton is common, and lameness with or without bone swellings may be seen. In rare cases, the fungus spreads throughout the body to cause a proliferative bone infection. The bones, however, lack the lytic lesions typical of canine osteosarcoma.

As you can see, while some similarities exist between the diseases, it is highly unlikely to have a canine osteosarcoma misdiagnosis.
