Hematopathology / BONE MARROW BIOPSIES

The medical records of 21 patients evaluated for mastocytosis and 2 patients seen for follow-up of known mastocytosis who underwent bilateral iliac crest aspirations and biopsies were reviewed retrospectively to determine whether mastocytosis could be confirmed in each of a patient’s biopsy specimens. In 19 cases (83%), each biopsy specimen showed evidence of mastocytosis; however, in 4 cases (...

We report 2 cases of biclonal CLL. Two elderly men were encountered with an absolute lymphocytosis consisting of the typical CD5+, CD19+, CD23+ B-cell population seen in CLL; however, immunoglobulin light chain rest...
