label_lc: rhabdoid tumor of the kidney
description: "A highly aggressive, extremely rare neoplasm of the kidney that is usually seen in children. The term rhabdoid is used because the tumor cells resemble rhabdomyoblasts but lack myogenic markers, and pathologic diagnosis requires familiarity with these microscopic features plus awareness that adult onset is possible. It can be associated with abnormalities of chromosome 22. It is characterized by the presence of cells with a large eccentric nucleus, prominent nucleolus, and abundant cytoplasm."
