Basket cells or shadow cells of Gumprecht: a scanning electron microscope study, and the correlation between percentages of basket cells, and cells with altered chromatin structure (dense cells), in chronic lymphocytic leukemia.
For over 50 years the received wisdom has been that the shadow cells of Gumprecht otherwise known as basket cells (BC) are in artefact, produced during preparation of films when a drop of blood is spread on a slide. The assumption has been that they are therefore of no significance. They are commonly seen in blood films from patients with lymphoproliferative syndromes and particularly in chronic lymphocytic leukemia (CLL). In 96 patients with CLL a statistically significant correlation existed between the basket cells observed in films and the lymphocytes with dense chromatin (DC) determined by flow-cytometry. There was no statistically significant correlation between the number of BC and DC, and the anatomic-clinical stage of the disease.
