pleomorphic rhabdosarcoma
Definition
Noun: - A specific, aggressive form of cancer (rhabdomyosarcoma) that arises in the skeletal muscles, most commonly in the limbs of adults. It is characterized by cancer cells that vary greatly in their size and shape (pleomorphic).
Usage
This is a highly specialized medical term used in pathology and oncology to diagnose and classify a rare type of soft tissue sarcoma. - The biopsy results confirmed the presence of a pleomorphic rhabdosarcoma in the patient's thigh muscle. - Treatment for pleomorphic rhabdosarcoma often involves a combination of surgery, radiation, and chemotherapy.
Advanced Usage
- The term is often used in contrast to other subtypes of rhabdomyosarcoma, such as embryonal or alveolar, which are more common in children. Its occurrence in "older adults" is a key distinguishing feature in its clinical description.
