Soft-tissue lumps and bumps.

Soft-tissue masses of the extremities and torso are a common problem encountered by the orthopaedic surgeon. Although these soft-tissue masses are often benign, the orthopaedic surgeon must be able to recognize the features key to differentiating benign and malignant masses. An understanding of the epidemiology and clinical presentation of soft-tissue masses is needed in order to outline a practical approach to evaluation and surgical management.
