Distal femoral chondroblastoma
Keywords:
chondroblastoma, knee tumors, benign tumors, cartilaginous tumors, bone curettage.Abstract
Introduction: Bone tumors are common in pediatric ages, especially those located in the knee joint. However, there are extremely rare histological types such as chondroblastoma.
Objective: To present the case of a patient with chondroblastoma of the knee.
Case report: This is the case of an 18-year-old male, mixed-race patient, with no known comorbidity, with clinical record 691343. He attended the Orthopedics and Traumatology Clinic for pain and inflammation of the left knee. The response was limited to outpatient treatment with analgesics and oral nonsteroidal anti-inflammatory drugs. The symptoms lasted approximately six months and they behaved in the form of crises. The pain increased after physical activity. Imaging studies suggested the presence of chondroblastoma. Based on the clinical and imaging elements, the case was discussed with the multidisciplinary team and surgical intervention was decided. The tumor was removed and sent to the pathology department, which confirmed the presence of chondroblastoma.
Conclusions: Chondroblastoma is a rare benign bone tumor, characterized by pain and functional impotence of the damaged joint. It is usually located in the epiphysis and is treated with curettage with or without bone filling.
