Ankle tumor

A tumor of the ankle joint can arise from the bone, cartilage, or soft tissue around the joint and is extremely rare.These tumors may be benign, malignant, or indeterminant. The radiologist will give a likelihood of the type of tumor it is based on its imaging characteristics.A bone tumour, or bone cancer, is a primary cancer that starts in the bone or adjacent cartilage. The tumours can be benign or malignant. Benign nonaggressive bone tumor types include an osteoma, osteoclastoma (giant cell tumours) or osteochondroma.In general, aggressive bone tumors are more common in children, adolescents and young adults. The most common types of malignant bone tumours in young adults are chondrosarcoma and osteosarcoma. A chondrosarcoma originates in the cartilage most commonly of the longbones: femur and humerus. An osteosarcoma is the second most common bone cancer and is rarely found in the shoulders, but is more common in the knees, tibiae, and in older people around the hip or jaw. Rarer types of bone cancer are: fibrosarcoma, angiosarcoma, and undifferentiated high-grade pleomorphic sarcoma. Until the dominant tumor tissue type is known, the tumor type is generally called a sarcoma.Soft tissue tumours common around a joint are synovial chondromatosis, pigmented villonodular synovitis, synovial sarcomas, lipomas, fibromas, desmoid tumours, leiomyoma, leiomyosarcoma, and synovial sarcoma.*Not covered in patients over 1.73m in height.*
