Chondroblastoma[edit]
Chondroblastoma is a rare benign tumor that originates from the cartilage-producing cells known as chondroblasts. It typically occurs in the epiphysis of long bones, most commonly affecting the femur, tibia, and humerus. Chondroblastoma is most frequently diagnosed in adolescents and young adults, with a higher prevalence in males.
Pathophysiology[edit]
Chondroblastoma arises from the chondroblasts in the epiphyseal plate of bones. These tumors are characterized by the production of immature cartilage and are composed of chondroblasts, multinucleated giant cells, and a chondroid matrix. The histology of chondroblastoma shows a distinctive "chicken-wire" calcification pattern.
Clinical Presentation[edit]
Patients with chondroblastoma typically present with localized pain and swelling in the affected area. The pain is often progressive and may be associated with joint effusion and limited range of motion. In some cases, the tumor may cause pathological fractures.
Diagnosis[edit]
The diagnosis of chondroblastoma is primarily based on imaging studies and biopsy. X-rays typically show a well-defined, lytic lesion in the epiphysis of the affected bone. Magnetic resonance imaging (MRI) and computed tomography (CT) scans can provide further details about the extent of the tumor and its relationship with surrounding structures. A biopsy is essential to confirm the diagnosis and differentiate it from other bone lesions.
Treatment[edit]
The primary treatment for chondroblastoma is surgical curettage and bone grafting. In some cases, en bloc resection may be necessary, especially if the tumor is recurrent or aggressive. Radiofrequency ablation is an alternative treatment option for small, accessible lesions. Post-surgical follow-up is crucial to monitor for recurrence, which occurs in approximately 10-20% of cases.
Prognosis[edit]
Chondroblastoma is a benign tumor with a good prognosis following appropriate treatment. However, due to its potential for recurrence, long-term follow-up is recommended. Malignant transformation is extremely rare.
