Digital cases

- Case 120 (HPC:120) : Osteoblastic osteosarcoma
- Case 127 (HPC:127) : Osteoblastic osteosarcoma
- Case 166 (HP:166) : Osteoblastic osteosarcoma
- Case 157 (HPC:157) : giant cell-rich osteoblastic osteosarcoma
- Case 140 (HPC:140) : Osteoblastic osteosarcoma
- Case 11734: Femoral osteoblastic osteosarcoma

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

- osseous tumors (bone tumors)
