Chondroblastoma of the calcaneus: literature review and case presentation.

Abstract

Chondroblastoma is a benign neoplasm of bone and most often arises from the epiphysis of long bones. Recognition of this tumor can be difficult and is often only confirmed on histological examination. Radiographic studies can demonstrate findings that mimic other tumors such as giant cell and aneurysmal cysts. Proper identification and management of this tumor has as high as a 90% success rate in eradication.
