Acquired lipidosis of marrow macrophages: birefringent blue crystals and Gaucher-like cells, sea-blue histiocytes, and grey-green crystals.

Acquired lipidosis of marrow macrophages: birefringent blue crystals and Gaucher-like cells, sea-blue histiocytes, and grey-green crystals.

Three varieties of compound lipid inclusions occurring as a secondary phenomenon in marrow macrophages are detectable and distinguishable by Romanowsky staining, ultraviolet fluorescence, and polarised light. Birefringent blue crystals and Gaucher-like cells form one variety, sea-blue granules another, and grey-green crystals a third. All occur chiefly in myeloid leukaemias, either acute or chr...

Sea-blue histiocytes and Gaucher cells in bone marrow of patients with chronic myeloid leukaemia.

A retrospective study of 211 bone marrow aspirates from patients with chronic myeloid leukaemia (CML) was undertaken to assess the incidence of Gaucher cells and sea-blue histiocytes. A significant correlation between the presence of these cells and prolonged survival was seen. Such storage histiocytes occurred most often during periods of relapsed chronic phase. This study shows that Gaucher c...

Sea-blue-colored histiocytes associated with bone marrow granulomas.

A 77-year-old man was admitted for evaluation of pancytopenia. His blood examination revealed hemoglobin 9.7 g/dL, platelet count 149 3 10/L, and white blood cell count 3.2 3 10/L with normal differential. Peripheral blood smear showed red blood cells with anisocytosis, microcytes, and teardrop-shaped cells. There was mild leukopenia with relative monocytosis and normal platelets. Bone marrow b...

Tunable photonic crystals with partial bandgaps from blue phase colloidal crystals and dielectric-doped blue phases.

Blue phase colloidal crystals and dielectric nanoparticle/polymer doped blue phases are demonstrated to combine multiple components with different symmetries in one photonic material, creating a photonic crystal with variable and micro-controllable photonic band structure. In this composite photonic material, one contribution to the band structure is determined by the 3D periodic birefringent o...
