Extraskeletal cartilaginous and osseous tumors

Abstract

Except for myositis ossificans, both osseous and cartilaginous tumors of the soft tissues are uncommon. The radiographic and/or magnetic resonance imaging (MRI) appearance of these tumors and tumor-like lesions frequently suggests a specific diagnosis. Even when a specific diagnosis cannot be obtained, knowledge of the various types of lesions is essential to make a relevant differential diagnosis.
