Definition

Noun: A highly malignant (cancerous) tumor that originates from striated muscle cells. Striated muscle is the type of muscle attached to bones, responsible for voluntary movement (skeletal muscle). This type of cancer is aggressive and can spread quickly.

Usage

"Rhabdomyosarcoma" is a specialized medical term used primarily in oncology (the study of cancer) and pathology. It describes a specific, rare type of soft tissue sarcoma. * The biopsy confirmed the diagnosis of rhabdomyosarcoma. * Treatment for rhabdomyosarcoma often involves a combination of surgery, chemotherapy, and radiation. * Pediatric oncologists see cases of rhabdomyosarcoma more frequently than adult oncologists do.

Advanced Usage
  • The term is often modified by its histological subtype (e.g., , ) to specify the tumor's appearance under a microscope, which can influence prognosis and treatment.
    • Alveolar rhabdomyosarcoma is generally associated with a poorer outcome.
  • In medical literature, it is frequently abbreviated as RMS.
Variants and Related Words
  • Rhabdomyoma (noun): A rare, typically benign (non-cancerous) tumor also arising from striated muscle. This is a distinct, less dangerous condition.
  • Sarcoma (noun): A broad category of cancers that originate in connective tissues like bone, muscle, fat, or cartilage. Rhabdomyosarcoma is a subtype of sarcoma.
  • Myosarcoma (noun): A general term for a malignant tumor of muscle tissue.
Synonyms
  • Malignant rhabdomyoma (an older, less specific term)
  • RMS (common medical abbreviation)
