Bone marrow aspiration. (a) Wright-Giemsa staining (x1,000) and (b) myeloperoxidase staining (x1,000). Arrows indicate blasts. Blasts presented with loose reticular chromatin and a high nucleus-to-cytoplasm ratio. Their size ranged from medium to large, and some showed cytoplasmic nucleoli and granules. Most blasts were myeloperoxidase negative.

Most blasts were myeloperoxidase negative, although some were positive (Figure 1).

G-banding of tumor cells and T cells in peripheral blood samples revealed the t(7;7)(p15;p22) translocation [20/20] (Figure 2) and 46, XX [20/20], respectively; thus, the novel translocation was observed.
