FIGURE 22-1B Niemann-Pick disease (BM ×1000).




Description:


The Gaucher cell is a macrophage 20 to 80 μm in diameter, with one or more small, round to oval eccentric nuclei; cytoplasm has crumpled tissue paper appearance; found in bone marrow, spleen, liver, and other affected tissue.



Description:


The Niemann-Pick cell is a macrophage, 20 to 90 μm in diameter, with a small eccentric nucleus and foamy cytoplasm. It is found in bone marrow and lymphoid tissue. The peripheral blood of patients with Niemann-Pick disease may exhibit vacuolated lymphocytes.

Description:


Deep purple to lilac granules difficult to distinguish from toxic granulation; occur in neutrophils and occasionally eosinophils and basophils

FIGURE 22–1E May-Hegglin Anomaly. Note Döhle-like body at arrow (PB ×1000).



Description:


Characterized by thrombocytopenia with large platelets and large basophilic inclusions resembling Döhle bodies in granulocytes and monocytes with the absence of toxic granulation






Note:


These inclusions are sporadically visible by light microscopy but always detectable by electron microscopy. The ultrastructure varies from that of Döhle bodies.
