Epidemiology
A benign tumor of skeletal muscle, rare in extracardiac soft tissue. Its name resembles that of rhabdomyosarcoma, but they are different diseases: this one is benign and does not spread.
Basic features
Soft-tissue rhabdomyoma very rarely affects the musculoskeletal system; its appearance as a mass in a limb, the pelvis, or the chest wall is exceptional and makes it necessary to confirm that it is not a rhabdomyosarcoma.
Usual treatment
Complete local resection is usually curative and is indicated for symptoms, growth, or the need to confirm the diagnosis.
Outcomes and prognosis
It does not metastasize and has an excellent prognosis; local recurrence is uncommon after complete resection.
