Sarcomas are a varied and a very rare group of malignant tumors made of cartilage, muscle, vascular or hematopoietic tissues and hence sarcoma is a cancer that results from transformed cells of mesnchymal origin. These are different from tumor that originates from epithelial cells which are known as carcinoma.
Classification of Sarcomas
Sarcomas are classified according to the type of tissues that they resemble but majorly they are of two types: bone and soft tissue.
Soft tissue sarcomas mostly form in fat, cartilage, muscle, blood vessels and other supportive tissues of the body with liposarcomas, rhabdomyosarcomas and osteosarcomas forming in fat, muscle and bone tissues respectively.

Apart from being named in respect to the tissues they originate from, sarcomas are further graded as either low, intermediate or high on the basis and frequency of certain cellular and sub cellular characteristics associated with malignant biological behavior.
Types of Sarcoma
There are several types of sarcoma cancer and they include the following:
Sarcoma botryoides is the type of sarcoma that is usually found along the walls of structures that are lined with mucus for example the bile ducts or urinary ducts of infants or the vaginal walls of females below 8 years.
Chondrosarcoma is a cancer made of cells originating from transformed cells that form cartilage. Almost 30% of skeletal system cancers are chondrosarcoma and can present at any age.
An osteosarcoma is a cancerous tumor that forms in a bone and is most prevalent amongst young people.
An epithelioid sarcoma is a rare soft tissue tumor with an epitheliod pattern. It is common among young adults.
An angiosarcoma is a sarcoma that originates from malignant cancer of endothelial-type cells that line walls of the vessels (such as blood vessels).
Also known as phyllode tumors, cystosarcoma phyllodes are usually large masses that grow so fast and that form from the stromal cells of the breast.
