Histology: 9220/09 chondroma NOS
In this scenario, the primary is stated to originate in the skull. Benign tumors of bone are not reportable.
Chondroma is a rare, benign tumor that tends to arise at the base of the skull, especially in the area near the pituitary gland. The chondroma is composed of cartilage formed by the meninges and is usually attached to the dura mater, the outermost layer of the meninges. It can grow to a large size and can occur as single or multiple tumors. (Information taken from the American Brain Tumor Association (ABTA) web site)
