Leukocytes Unit
Abnormalities of Leukocytes and their associated diseases - Part 1
| Abnormality | Description | Associated Diseases |
|---|---|---|
| Auer bodies | round or rod-like, 1-6 um long, red-purple, refractive inclusions in neutrophils | Acute myelocytic leukemia |
| Chediak-Higashi anomaly | Grey-green, large cytoplasmic inclusions resembling Dohle bodies | Chediak-Higashi syndrome |
| Dohle bodies | Small (1-2um) blue cytoplasmic inclusions in neutrophils | infections or inflammatory diseases, burns, myelocytic leukemia, and myeloproliferative syndromes |
| Leukemic cells | presence of lymphoblasts, myeloblasts, monoblasts, myelomonoblasts, promyelocytes (none seen in a normal peripheral blood smear) | Leukemia (acute & chronic), leukemoid reaction, severe infectious or inflammatory diseases, myeloproliferative syndromes, malignancy, infectious mononucleosis, & myelophthisis. |
| May-Hegglin anomaly | Basophilis RNA cytoplasmic inclusions of leukocytes. Similar to Dohle bodies | May-Hegglin syndrome |
| Pelger-Huet anomaly | Neutrophil with bi-lobed or no segmentation of nucleus. Chromatin is coarse and cytoplasm is pink with normal granulation. | Hereditary; myelocytic leukemias, and myeloproliferative syndromes |
| Plasmacytosis | Plasma cells are present (none normally seen in peripheral blood) | Multiple myeloma, plasma cell leukemia, malignancy, chronic renal disease, aplastic anemia, TB; any severe infectious or inflammatory condition |
| Smudge cell | Disintegrated lymphocyte | Chronic lymphocytic leukemia |
| Toxic granulation | Coarse black or purple cytoplasmic granules | Infectious or inflammatory diseases |
| Alder's Anomaly | Prominent azurophilic granulation in leukocytes; similar to toxic granulation | Gargoylism and associated hereditary disorders |
