Soft-tissue tumors are tumors, or abnormal growths, that develop in the body’s connective tissue, which can include anything in the musculoskeletal system other than bone tissue. For instance, soft-tissue tumors can grow in fat and muscle as well as tendons, fibrous tissue, nerves, and blood vessels. In terms of where they are located, soft-tissue tumors are most often found in the body’s lower extremities, trunk and abdomen, and upper extremities.
There are two types of soft-tissue tumors: those that are malignant (soft-tissue sarcomas) and those that are benign, or noncancerous. Most of the time, soft-tissue tumors are not sarcomas, but lumps of noncancerous tissue. Typically, these soft-tissue tumors develop in adults and are more common tumors than bone sarcomas, or bone cancer.
Patients often first notice a lump of soft-tissue mass. In order to know for certain that the mass is not soft-tissue sarcoma, an oncologist will perform tests and make a diagnosis. Typically, a biopsy of the soft tissue is taken, and if sarcoma is discovered, the orthopaedic oncologist, the doctor specializing in diagnosis and treatment of bone cancers and diseases, will talk to the patient about their soft-tissue sarcoma and treatment options.
To better understand a cancerous growth like a malignant soft-tissue tumor, the tumor will be classified by both its tissue type as well as grade. The lower the grade, the lower the risk for aggressive growth at the original site or for the tumor to metastasize later on. Doctors will often schedule an imaging test like an MRI scan for a patient with a soft-tissue tumor. This will also allow the orthopaedic oncologist to more closely examine the tumor and see if the tissues are normal, if there are sarcoma tissues, or whether or not the tumor is impacting any nearby tissues, like nerves or blood vessels.
At University Orthopaedic Surgeons, our orthopaedic oncologist, Dr. Anna Wallace, is dual-fellowship-trained in orthopaedic trauma and orthopaedic oncology, making her more than qualified to assess, diagnose, and treat all types of soft-tissue tumors.
Build Your Knowledge of Soft-Tissue Tumors and Orthopaedic Oncology
If you have a soft-tissue mass and were recently diagnosed with soft-tissue sarcoma, it can be helpful to build your knowledge about how it is treated. Here are some terms that can help you better understand soft-tissue tumors, bone disease, and related issues:
- Benign tumor: Tumors, including bone tumors, can be noncancerous (benign). For instance, osteochondroma is a type of benign bone tumor. It tends to grow at the end of long bones, like the leg bones.
- Bone cyst: A noncancerous type of fluid-filled bone tumor that is more common in children. A single bone cyst may also be referred to as a nonossifying fibroma unicameral.
- Enchondroma: A type of cartilage tumor that is benign. Enchondromas can sometimes transform into chondrosarcomas.
- Fibrous dysplasia: A condition where fibrous tissue begins to grow and replace normal bone and marrow, which weakens the bone.
- Giant cell tumors: Bone tumors that grow rapidly in the rounded end of the bones, usually near the knee.
- Lipoma: A noncancerous soft-tissue tumor made up of body fat.
- Malignant bone tumor: A cancerous tumor that occurs in a hard structure such as bone or cartilage versus a soft tissue such as muscle or blood vessels.
- Oncology: The field of medicine focused on diagnosing cancer as well as cancer treatment. Oncologists are doctors who work within the field of oncology and diagnose and treat cancer patients.
- Orthopaedic oncology: Refers to the field of medicine focused on helping patients who have a sarcoma and bone disease that has developed somewhere in the musculoskeletal region, such as the bones and cartilage, or soft tissues, such as the muscles.
- Primary bone cancer: When a bone cancer develops in the bone first, like osteosarcoma, it is called a primary bone cancer. When cancerous cells move to the bones from a different location, it is not a primary bone cancer. Instead, it is a metastatic bone disease or bone metastases.
- Sarcoma: An overall term for bone cancer. This includes soft-tissue tumors that are malignant.
