Quick Summary

Rhabdomyosarcoma is a malignant tumor that originates in skeletal muscles. It is composed of striated muscle fibers and is a type of muscle tumor. While leiomyomas are benign smooth muscle tumors and rhabdomyomas are rare, usually benign striated muscle tumors, rhabdomyosarcomas are specifically cancerous. These tumors most commonly develop in the muscles of the arms or legs. A concerning characteristic of rhabdomyosarcoma is its potential to recur even after the affected limb has been amputated. Symptoms may include a slowly growing mass that can develop over many years before diagnosis.12
