[Pelvic chondroblastoma in an adolescent. New treatment approach].

概要
Surgical management of tumors located in the spine and the pelvis involves greater difficulty. Moreover, these tumors are usually very large and vascularized. Preoperative embolization of the internal iliac artery is a relatively safe procedure that may reduce the risk of bleeding and local recurrence in the case of benign tumors. Chondroblastoma is a tumor that is rarely located in the pelvis; its more frequent location is the triradiate cartilage. We describe a case of a chondroblastoma with a relapsing aneurysmal cystic component in the acetabulum of an adolescent patient. Treatment consisted of embolization of the internal iliac artery, fluid hyperthermia, hydrogen peroxide and bone marrow application. The patient was found to be asymptomatic at the 5-year postoperative follow-up. The technetium (99mTc) sestamibi scan was negative for tumor activity and found no lung metastases.
