Mast cell sarcoma
Medical condition
From Wikipedia, the free encyclopedia
Mast cell sarcoma is an extremely aggressive[2] form of sarcoma made up of neoplastic mast cells. 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] Mast cell sarcoma should not be confused with extracutaneous mastocytoma, a rare benign mast cell tumor without destructive growth. In the cases observed, mast cell sarcoma terminated quickly as mast cell leukemia; one of the most aggressive human cancers.[5]
