Macroscopy
Some osteoblastic osteosarcomas may appear grey-tan and randomly granular (pumice-like), while others become denser, sclerotic and more yellow-white.
Microscopy
Bone and/or osteoid are the predominant matrix in osteoblastic osteosarcoma. The extremes of matrix production are thin, arborising osteoid (i.e., filigree) to dense, compact osteoid and bone (i.e., sclerotic).
Variants
giant cell-rich osteoblastic osteosarcoma
