Objective: To investigate the morphological manifestation of bone marrow cells in newly-diagnosed patients with POEMS syndrome.
Methods: The bone marrow cells in 155 patients with POEMS syndrome were classified and counted by OLYMPUS BX51 microscope, and the abnormal morphology of bone marrow cells was observed.
Results: The count of plasma cells with normal morphology was 83.9% (130/155), the count of plasma cells with abnormal morphology (< 5 percent) was 12.3% (19/155), the count of plasma cells with obvious abnormal morphology (> 10 percent) was 3.8% (6/155) in patients with POEMS syndrome.
Conclusion: The morphology of plasma cells in the most patients with the POEMS syndrome are normal, the minor patients of the POEMS syndrome have little abnormal plasma cell morphology, the extremely few patients showed obvious morphological abnormality in the bone marrow plasma cells. The higher proportion of plasma cells, the more easily and more abnormal plasma cells will be found.
