Chondroblastoma

Codman's tumor

Overview

Type of disease: Rare conditions

Chondroblastoma is a rare benign (non-cancerous) bone tumor which occurs at the ends of the long bones of the body, most often the upper leg and upper arm bones. Though chondroblastoma can occur at any age and either gender, it most often affects males under the age of 25 years. For children, it is the most common growth plate tumor. The tumors start growing in the chondroblasts, which are specialized cells that are involved in making cartilage. Cartilage is the soft, elastic tissue that cushions the joints. Symptoms of chondroblastoma include muscle degradation (or wasting away) and decreased joint mobility increased pain.

This benign tumor does in rare cases become cancerous and spread to the lungs. Surgical removal of the tumor is recommended. Unfortunately, there is a chance of tumor regrowth after surgery, ranging from 10-35%. The cause of chondroblastoma is largely unknown but research is continuing. Current treatment is surgery to remove the tumor and affected bone tissue followed by bone graft. A bone graft uses the patient’s own healthy bone or donated bone to replace the bone damaged by the tumor. If you or a family member has been diagnosed with chondroblastoma, talk to your doctor and specialists about the most current treatment options.
