It seems a difficult case, regarding benign vs. malignant. It does not have the features of schwannoma (capsule, thick vessels, lymphoid aggregates), even though the mass looks demarcated (not supporting neurofibroma). I didn't see clearly the bone destruction from the photos provided. The cells look somewhat chondroid and background myxoid. IHC to rule out nerve sheath tumor might be helpful. If IHC is negative and it is truly osteoid formation, I tend to think it might be a low grade osteosarcoma.
