Confirmation was achieved by performing an open biopsy and histopathological examination of the specimen. The final diagnosis of chondroblastoma was confirmed in view of there being a marked cellular chondroid component rather than fibrous component in the histology slides. Thorough curettage in such cases can provide an ample diagnostic specimen as well as being a definitive treatment, and may lead to complete recovery as found in this case.

Q3: How long would you follow up this patient?
