In general, the other types of sarcomas are extremely rare in children and young adults. These include:
- alveolar soft part sarcoma (in sac-like cavities such as those in the lungs)
- fibrosarcoma and dermatofibroma (in fibrous tissues)
- infantile hemangiopericytoma (in connective tissue surrounding capillaries)
- leiomyosarcoma (in smooth muscles)
- liposarcoma (in cells that develop into fat tissue)
- synovial sarcoma (in fluid and tissues of the joint cavities, bursae, and tendons)
Treatment of these soft tissue sarcomas are individualized and can include a combination of systemic chemotherapy, surgery, and radiation therapy.
