Chondroblastoma is a rare, benign, locally aggressive bone tumor that typically affects the epiphyses or apophyses of long bones. It is thought to arise from an outgrowth of immature cartilage cells (chondroblasts) from secondary ossification centers, originating from the epiphyseal plate or some remnant of it.

Chondroblastoma is a rare, benign, locally aggressive bone tumor that typically affects the epiphyses or apophyses of long bones. It is thought to arise from an outgrowth of immature cartilage cells (chondroblasts) from secondary ossification centers, originating from the epiphyseal plate or some remnant of it.
Chondroblastoma is very uncommon, accounting less than 1% of all bone tumors. (The chances of having this condition are roughly one in a million.) It affects mostly children and young adults with most patients being less than 20 years of age. Chondroblastoma shows a predilection towards the male sex, with a ratio of male to female patients of 2:1. The most commonly affected site is the femur, followed by the humerus and tibia. Less commonly affected sites include the talus and calcaneus of the foot and flat bones.
