inguinal lymphadenopathy (B). Severe hypercellular marrow was occupied
by blasts (C), presenting agranular small cytoplasm and fine chromatin
(D). Bone marrow showed severe fibrosis (MF-3) (E) (magnification of all

Figure 2. Blasts were positive for CD4, CD56, CD123, CD303,
TCL-1, cMyc, and Bcl-2 and negative for TdT, myeloperoxidase, CD3, and
CD8. Positive rate of Ki67 was approximately 30% (magnification of all
