Rieder cells

Rie·der cells

(rē'dĕr),
abnormal myeloblasts (12-20 mcm in diameter) in which the nucleus may be widely and deeply indented (that is, suggestive of lobulation), or may actually be a bilobate or multilobate structure; such cells are frequently observed in acute leukemia, and probably represent a more rapid maturation of the nucleus than that of the cytoplasm.
