| Rieder cell leukaemia | A special form of acute granulocytic leukaemia in which the affected tissues and the circulating blood contain relatively large numbers of atypical myeloblasts (i.e., Rieder cells) that have the usual, faintly granular, immature type of cytoplasm, and a bizarre, comparatively mature nucleus with several wide and deep indentations (suggestive of lobulation). (05 Mar 2000) |

| Rieder cells | Abnormal myeloblasts (12 to 20 um in diameter) in which the nucleus may be widely and deeply indented (i.e., suggestive of lobulation), or may actually be a bi-or multi-lobate structure; such cell's are frequently observed in acute leukaemia, and probably represent a more rapid maturation of the nucleus than that of the cytoplasm. (05 Mar 2000) |
| Rieder's lymphocyte | An abnormal form of lymphocyte that has a greatly indented (or lobed), slightly twisted nucleus; such cells are usually observed in certain examples of chronic lymphocytic leukaemia. (05 Mar 2000) |

| Rieder c. |
a myeloblast seen in a type of acute myelogenous leukemia (Rieder's cell leukemia) and chronic lymphocytic leukemia; it has a nucleus with wide and deep indentations suggesting lobulation, which may represent asynchronism of nuclear and cytoplasmic maturation. Called also Rieder's lymphocyte.

| Rieder cell l. |
a form of acute myelogenous leukemia in which the blood contains Rieder cells, asynchronously developed lymphocytes that have immature cytoplasm and a lobulated, indented, comparatively more mature nucleus.
