Figure 2: (a) Cellular smear showing numerous myeloid cells in various stages of maturation, occasional group of erythroid cells (red arrow), and scattered megakaryocytes (Giemsa, ×200). (b) Large multinucleated and multilobulated megakaryocytes (Pap, ×400). (c) Cell block section revealing scattered megakaryocytes along with numerous myeloid series cells (H and E, ×200). (d) Bone marrow biopsy shows markedly hypocellular marrow with diffuse fibrosis of marrow spaces (H and E, ×200). Inset shows megakaryocytes. (e) Fibrotic areas show increase in reticulin with extensive intersection (reticulin, ×200). (f) Masson's trichrome stain showing diffuse blue-stained coarse bundles of collagen (MT, ×200)
