A sarcoma is a malignant tumor, a type of cancer that arises from cells of mesenchymal (connective tissue) origin. [1] [2] Connective tissue is a broad term that includes bone, cartilage, muscle, fat, vascular, or other structural tissues, and sarcomas can arise in any of these types of tissues.
A malignant peripheral nerve sheath tumor is rare, but is one of the most common frequent soft tissue sarcoma in the pediatrics population. About half of these cases also happen to occur along with neurofibromatosis type 1 (NF-1), which is a genetic mutation on the 17th chromosome which causes tumors along the nervous system.
Spindle cell sarcoma is a type of connective tissue cancer. The tumors generally begin in layers of connective tissue , as found under the skin, between muscles, and surrounding organs, and will generally start as a small, inflamed lump, which grows in size.
Undifferentiated pleomorphic sarcoma (UPS), also termed pleomorphic myofibrosarcoma, [1] high-grade myofibroblastic sarcoma, and high-grade myofibrosarcoma, [2] is characterized by the World Health Organization (WHO) as a rare, poorly differentiated neoplasm (i.e., an abnormal growth of cells that have an unclear identity and/or cell of origin). [3]
Embryonal rhabdomyosarcoma is generally associated with better prognosis than alveolar rhabdomyosarcoma, with a five-year survival prognosis of 82% and 53%, respectively. [26] [17] This may be due to the more aggressive and metastatic nature of ARMS that can be attributed to its PAX3–FOXO1 or PAX7–FOXO1 gene fusions. [27]
A sarcoma is a tumor made of cells from connective tissue. Mast cell sarcoma is an extremely rare tumor. The largest analysis to date comprises 34 cases. [3] Prognosis is extremely poor. People with a mast cell sarcoma have no skin lesions, and pathology examination of the tumor shows it to be very malignant with an aggressive growth pattern. [4]
