sea-blue his·ti·o·cyte

a histiocyte containing cytoplasmic granules that stain bright blue with hematologic stains (for example, Wright-Giemsa); found in bone marrow and in the spleen, associated with hepatosplenomegaly and thrombocytopenic purpura and in other blood diseases.

While not always statistically significant, certain features were more common in CVD than in the control group (Figure), including (1) abnormal bony trabeculae, (2) megaloblastoid changes in the erythroid lineage, (3) sea-blue histiocytes (SBHs), and (4) ALIP of the granulocytic lineage.
Sea-blue histiocytes, although relatively rare, have been reported in a variety of conditions ranging from the more commonly cited Niemann-Pick disease, to an effect of total parenteral nutrition including fat emulsions, to a variety of hematologic malignancies including non-Hodgkin lymphoma, light chain deposition disease, myeloproliferative neoplasms, and MDS.
Of these findings, only sea-blue histiocytes were unique to the CVD group (hematoxylin-eosin, original magnification 340 [A]; modified Wright-Giemsa, original magnifications31000 [B] and 3500 [C]; original magnification 3200 [D]).
