Question:

Reportability/Primary Site--Brain and CNS: Is a chondroma, NOS or a chondroblastoma, NOS that occurs in an intracranial site or along the spinal cord reportable? See Discussion.

Discussion:

In ICD-O-3, chondroma and chondroblastoma are site-associated morphologies for bone. If a chondroma or a chondroblastoma occurs along the spinal cord, is this one of those situations where we can be quite comfortable with a default site to bone and not to spinal cord?

Reference: ICD-O-3; Primary Central Nervous System Tumors, NPCR Training Materials 2004; SINQ 20021152

Answer:

Chondroma, NOS or chondroblastoma, NOS occuring in intracranial sites or along the spinal cord are not reportable.

Chondroma, NOS and chonroblastoma, NOS are benign tumors of the bone itself, not the intracranial contents.
