Digital cases
Case 115 : Chondroblastic osteosarcoma of the calcaneum
Definition : Chondroblastic osteosarcoma (OS) accounts for about 25% of all cases of OS.
Localization
flat bones
- temporal bone (#20730902#)
Differential diagnosis
It can pose diagnostic difficulty on cytology, as the tumor cells may resemble the carcinomatous cells.
Prognosis
A chondroblastic subtype of osteosarcoma could be at risk to have a higher risk for late relapse. (#16426841#)
