Reassessment of H&E stained clot specimens and immunohistochemistry of phosphorylated Stat5 for histological diagnosis of MDS/MPN

Summary: Few studies have comprehensively analysed histopathological findings of bone marrow clots for diagnosis of haematopoietic cell dysplasia. In particular, a limited number of studies have assessed the use of haematoxylin and eosin (H&E) staining, which is generally considered less informative than May-Giemsa staining. In the current study, the utility of bone marrow clot specimens for diagnosis was examined using H&E staining and immunohistochemistry. Patients with myelodysplastic syndromes (MDS) and myelodysplastic/myeloproliferative neoplasm (MDS/MPN), including chronic myelomonocytic leukaemia (CMML), atypical chronic myeloid leukaemia (aCML) lacking Philadelphia chromosome, and juvenile myelomonocytic leukaemia (JMML), were selected for histological evaluation. H&E stained specimens were advantageous for observation of atypical basophilic staining of the cytoplasm and nucleus related to dysplasia. This finding was significantly supported for both MDS and MDS/MPN (p
