Central chondrosarcoma of long bones may infiltrate the cortex and supporting layers of the reactive bone. Nasal chondrosarcoma is the most common tumor of the nasal passages in the dog (28.8%), followed by the ribs (17.5%), appendicular skeleton (17.5%), extraskeletal sites(13%), and facial bones. CHONDROSARCOMA Chondrosarcoma is classified as central, peripheral, or juxtacortical, depending on whether the tumour arises from the medullary cavity, outside the bone, or in the cartilaginous cap of an osteochondroma lying on the outer surface. The most common locations for chondrosarcoma tumors are in the pelvis, hip and shoulder. Prognosis – The reported median survival of dogs with nasal chondrosarcoma has been found to be 210 days to 580 days with various treatments like radiation therapy, rhinotomy (incision made into the nose to drain accumulated pus) and radiation therapy combined and rhinotomy alone. The tumor can develop in the nasal cavity, ribs, pelvis, extraskeletal sites like mammary gland, heart, valves, aorta, larynx, trachea, vertebrae, facial bones, digits, and penis. Medium to large breeds like Boxers, German Shepherds and Golden Retrievers are at an increased risk of developing the disease. It is the second most common primary tumor of the bone in both humans and dogs that accounts for approximately 5% to 10% of all canine primary bone tumors. Physical examination is essential for evaluating the general health of the dog and also for detecting other illnesses if there is any. Bizarrely, bone cancer mainly occurs in giant-breed dog such as Great Danes. The following are some of the more common rabbit colors and markings or patterns that you may come across, many of which...

If osteoid is present, the neoplasm is classified as osteosarcoma, compound variety. But in case of oral metastasis, the median survival time has been estimated at 16-24 months. The tumor fills the nasal cavity by destroying turbinates (long narrow, curled bone shelf which protrudes into the breathing passage of the nose). Medium or large breed dogs are believed to be more likely to develop the condition. Sometimes, it is also important to find out if the dog would be able to manage on 3 legs where amputation is a potent possibility.

In cases of retrobulbar chondrosarcoma, due to impossibility of the eye closure, the cornea gets dry and keratitis and conjunctivitis can be observed. These growths are less common than both osteosarcomas and fibrosarcomas, though they still account for a sizable percentage of bone cancer cases in dogs. The The sizes of the tumors ranged from 3 cubic centimeters to 8,315 cubic centimeters. Some of the color names are self-explanatory, others are less so. The tumor tends to grow more slowly and develop metastasis later and with much less frequency than osteosarcoma. Some types of chondrosarcomas grow slowly and, provided they are removed completely, have a low risk of spreading to other organs and bones. Metastasis, when it does occur, is usually to the lungs, but other organs, such as the kidney, heart, liver and skeleton may also be affected. Overview of Chondrosarcoma of the Larynx and Trachea in Dogs. It can develop out of the tissues where cartilage normally does not exist.

The cancer is found in the pelvis area, bones around the nose, and the rib area. But when it does the common sites that come within its ambit may include lungs, kidney, liver, heart and skeleton. The mean age of dogs with extraskeletal osteosar- coma was 11 years (range, 9 to 15 years), and dogs with extraskeletal chondrosarcoma were 1 1, 14, and 17 years old. Death is mostly reported in case of metastatic disease. Larger breeds of dogs are more susceptible to chondrosarcoma, Boxers and German Shepherds having the highest occurrence. Chondrosarcomas are characteristic for their slow but progressive invasion of the surrounding tissues. The median survival time for dogs with skeletal chondrosarcoma varies between 201 and 1080 days, with treatment, depending upon the location and type of the tumor.3. In case of nasal chondrosarcoma, the signs may include sneezing, unilateral and sometimes bilateral purulent (pus), bloody discharge and nasal obstruction followed with bone destruction. However, they are sophisticated and highly adaptable. Chondrosarcoma Prognosis in Dogs. Untreated, canine intranasal tumors carry a poor prognosis.6 Chemotherapy does not decrease the metastatic rate or improve survival time in dogs with chondrosarcoma.

Most chondrosarcomas develop from the skeletal cartilage, but some extraskeletal chondrosarcomas occur in the tissues that possess preexisting cartilage. Laryngeal and tracheal chondrosarcomas are malignant, slow growing, progressive, invasive tumors of the larynx or voice box and trachea, which is the windpipe. The eye affected by CS of the orbit is non-functional, and due to destruction of the nasal septum and expansion of the tumor, a thick nasal discharge, difficult breathing, and nasal stridor are also present. They are often mistaken for benign (non-spreading) tumors because of their slow spread and lack of symptoms. Dogs with chondrosarcoma of the skull have life expectancy between 210 and 580 days - in our case it was 180 days - after the first alterations on the eye of the dog occurred.
