A malignant tumor of striated muscle is known as which of the following?

A malignant tumor of striated muscle is classified as rhabdomyosarcoma. This type of sarcoma originates from rhabdomyoblasts, which are the precursor cells to striated muscle fibers. Rhabdomyosarcoma is most commonly found in children and can occur in various parts of the body, including the head, neck, and genitourinary tract. It is characterized by aggressive behavior and the potential for metastasis, making it a significant concern in pediatric oncology.

In contrast, leiomyoma refers to a benign tumor of smooth muscle, typically found in organs like the uterus. Fibrosarcoma is a malignant tumor derived from fibrous connective tissue, and epithelioma generally refers to tumors arising from epithelial tissue, which is different from striated muscle. Understanding the type of muscle tissue involved is crucial, as treatment approaches and prognostic implications vary significantly among these tumor types.
