Brain tumors are classified according to histology, but tumor location and extent of spread are important factors that affect treatment and prognosis. Ependymomas arise from ependymal cells that line the ventricles and passageways in the brain and the center of the spinal cord. Ependymal cells produce cerebrospinal fluid (CSF). These tumors are classified as supratentorial or infratentorial. In children, most ependymomas are infratentorial tumors that arise in or around the fourth ventricle. According to the 2016 revision to the World Health Organization (WHO) classification of tumors of the central nervous system, ependymal tumors are classified into the following five main subtypes:
Adult soft tissue sarcomas can form almost anywhere in the body, but are most common in the legs, abdomen, arms, and trunk. There are many types of soft tissue sarcoma.

The cells of each type of sarcoma look different under a microscope, based on the type of soft tissue in which the cancer began.
