Conventional chondrosarcomas are graded I-III and more than 90% of cases are low to intermediate grade (I-II).
Chondrosarcoma signs and symptoms may include: 1 Increasing pain 2 A swelling or palpable mass 3 Fracture due to weakened bone
Other imaging tests, such as magnetic resonance imaging (MRI) and computerized tomography (CT), can offer additional information about the tumor. Doctors can confirm a diagnosis of chondrosarcoma by removing a sample of suspicious tissue with a needle or a scalpel and testing it in a lab.
Surgical removal of the tumor is the mainstay of chondrosarcoma treatment. Radiation and chemotherapy are rarely helpful in the treatment of chondrosarcoma.

Chondrosarcoma is a type of bone cancer that develops in cartilage cells. Cartilage is the specialized, gristly connective tissue that is present in adults and the tissue from which most bones develop. Cartilage plays an important role in the growth process.
Soft tissue sarcoma is a rare type of cancer that begins in the tissues that connect, support and surround other body structures. This includes muscle, fat, blood vessels, nerves, tendons and the lining of your joints. More than 50 subtypes of soft tissue sarcoma exist.
Patients diagnosed with bone metastases were identified using a diagnostic code (ICD-10 code for bone metastasis: C795).
A rare, slow-growing type of cancer that forms in soft tissues outside the bone and usually has certain changes in the NR4A3 gene that cause abnormal fusion proteins to be made. Extraskeletal myxoid chondrosarcomas usually occur in the thigh but may also occur in the knee, buttock, or chest and abdomen.

1. Introduction. Distinction between enchondroma (E) and low-grade chondrosarcoma (LGC) remains a challenge for any specialist on musculoskeletal sarcomas management including orthopaedic surgeons, pathologists, and radiologists (Table 1).Even in the most expert hands, these two entities can lead to a wrong diagnosis and, as a consequence, to an unsuitable treatment [1–3].

When they occur, signs and symptoms of chondrosarcoma may include: Increasing pain. A growing lump or area of swelling. Weakness or bowel and bladder control problems, if the cancer presses on the spinal cord.
Chondrosarcoma happens most often in the pelvis, hip and shoulder. More rarely, it can happen in the bones of the spine. Most chondrosarcomas grow slowly and may not cause many signs and symptoms at first.
Factors that can increase the risk of chondrosarcoma include: Increasing age. Chondrosarcoma occurs most often in middle-aged and older adults, though it can occur at any age. Other bone diseases. Ollier's disease and Maffucci's syndrome are conditions that cause noncancerous bone growths (enchondromas) in the body.
It's not clear what causes chondrosarcoma. Doctors know that cancer begins when a cell develops changes (mutations) in its DNA. A cell's DNA contains the instructions that tell it what to do. The instructions tell the cell to multiply quickly and to continue living when healthy cells would die.
Most chondrosarcomas grow slowly and may not cause many signs and symptoms at first. Some rare types grow rapidly and have a high risk of spreading to other areas of the body, which can make these cancers difficult to treat. Chondrosarcoma treatment usually involves surgery.
Primary central chondrosarcoma (intramedullary) is by far the most common subtype of conventional chondrosarcoma; however, secondary peripheral chondrosarcoma (tumors arising on the bone surface in the setting of a pre-existing osteochondroma) accounts for approximately 10% of cases.
Dedifferentiated chondrosarcoma is a rare biphasic sarcoma characterized by a low to intermediate grade hyaline cartilage neoplasm component which is juxtaposed with a high-grade malignant sarcoma typically consisting of pleo morphic spindle cells with ample mitotic activity and necrosis ( Fig. 9 ). A helpful diagnostic feature of dedifferentiated chondrosarcoma versus other malignant tumors in the differential diagnosis (high grade chondroblastic osteosarcoma, high-grade chondrosarcoma) is that dedifferentiated chondrosarcoma maintains a separation of the two components without mixing. Radiology is often helpful with the identification of dedifferentiated chondrosarcoma as these tumors may show distinct lower-grade and higher-grade components on advanced imaging ( Fig. 10 ). Dedifferentiated chondrosarcoma has numerous molecular abnormalities including IDH1/2 mutations and a poor overall prognosis with high rates of metastasis and death from disease. 10
The remaining 10-20% of chondrosarcomas comprise a group of variants including clear cell chondrosarcoma, mesenchymal chondrosarcoma and dedifferentiated chondrosarcoma. Of note (and despite its name), extraskeletal myxoid chondrosarcoma is not a true “chondrosarcoma” and is better classified as a translocation sarcoma of unknown histogenesis harboring with the canonical t (9;22) EWSR1-NR4A3 fusion ( Fig. 5 ). 6
Periosteal chondrosarcoma is a rare chondrosarcoma subtype representing 2.5% of all chondrosarcomas. Periosteal chondrosarcoma occurs in a younger age group with a peak incidence in the third decade of life and, like conventional central chondrosarcoma, has a male predominance.4 Periosteal chondrosarcoma predominantly affects metaphysis (fluted portion) of long bone and the tumor arises on the surface of the cortex generally not involving the medullary canal. Periosteal chondrosarcomas are typically larger than 5.0 cm and there is often invasion of the underlying cortex. In contrast to conventional chondrosarcoma, histologic grading does not predict outcome. Periosteal chondrosarcoma has a relatively low metastatic rate (5-12%) and metastases will generally spread to the lung. 5
Secondary peripheral chondrosarcoma is an uncommon subtype of conventional chondrosarcoma originating at the surface of the bone in a pre-existing osteochondroma, often in the setting of multiple hereditary exostosis (MHE).
Conventional Chondrosarcoma. The vast majority of chondrosarcomas (roughly 80-90%) are known as conventional intramedullary (central) and occur as a primary neoplasm in previously normal bone.1,2 Most conventional chondrosarcomas grow slowly and either do not metastasize or do so only late in their natural history.

Doctors can confirm a diagnosis of chondrosarcoma by removing a sample of suspicious tissue with a needle or a scalpel and testing it in a lab. A biopsy must be performed in a certain way so that it doesn't make it more difficult to remove the cancer during a later operation.
Tests and procedures used to diagnose chondrosarcoma include: Physical exam. Your doctor may ask about your signs and symptoms and examine your body to gather more clues about your diagnosis. Imaging tests. Imaging tests may include X-ray, bone scan, MRI and CT scan. Removing a sample of tissue for testing (biopsy).
Small and slow-growing chondrosarcomas in the arms and legs are sometimes treated with a procedure to scrape the cancer cells from the bone. The surgeon might apply cold gas or a chemical to kill any cancer cells that remain. The bone can be repaired with a bone graft or bone cement, if needed.
The goal of surgery for chondrosarcoma is to remove the cancer and a margin of healthy tissue around it. The type of surgery you undergo will depend on the location of your chondrosarcoma. Options might include: Scraping the cancer away from the bone.
Chondrosarcoma treatment often involves surgery to remove the cancer. Other treatments might be recommended in certain situations. Which options are best for you depends on where your cancer is located, how quickly it's growing, whether it has grown to involve other structures, your overall health and your preferences.
Chondrosarcoma is typically a very slow-growing cancer and chemotherapy targets cells that grow very quickly, so this treatment is generally not very effective. Some rare variations of chondrosarcoma do grow more swiftly, so chemotherapy may be helpful in these cases.
Radiation might be recommended for chondrosarcomas located in places that make surgery tricky or if the cancer can't be removed completely during surgery. Radiation may also be used to control cancer that spreads to other areas of the body.
