Morphological Transformation of Myeloma Cells into Multilobated Plasma Cell Nuclei within 7 Days in a Case of Secondary Plasma Cell Leukemia That Finally Transformed as Anaplastic Myeloma

Figure 1

Morphological changes in myeloma cells immediately after the development of plasma cell leukemia. The WBC count was 20.2 × 109/L, and 79.5% of them were composed of typical myeloma cells (1,000x, May–Grünwald-Giemsa staining).
