- Abstract
Enchondromas are common, painless and benign cartilage tumors, which often occur in the small bones of the hand and feet. The main symptoms of chondrosarcoma are localised pain, local swelling, or restricted joint movement. In the literature, a single enchondroma rarely becomes malignant; if it does, it is hard for physicians to reach the correct diagnosis by clinical examination. Herein, we report a case of a 51 year old male patient with a 17-month history of an enchondroma treated with surgery, who was presented to Liaoning Cancer Hospital & Institute in Shenyang, China. This patient had experienced ongoing pain in his right thigh for 6 months. Due to the patient's history of a single enchondroma, the patient was suggested clinical observation without a diagnosis, although MRI showed multiple abnormal signs in the right proximal femur 6 months ago. As pain worsened, medical imaging (plain films, CT and MRI scan) found the patient to have a destructive lesion in the right proximal femur with a high density soft tissue mass. The patient then underwent a biopsy, which confirmed the secondary chondrosarcoma was in the right proximal femur. Secondly, the patient received one course of adjuvant chemotherapy pre-operatively. Thirdly, the patient underwent an external hemipelvectomy and was followed up on a regular basis. The progressive pain in the right thigh was only a clinical sign of an enchondroma developed into chondrosarcoma.
