Figure 1

Histopathological images of the bone marrow (magnification 10x). (a) Biopsy section obtained on October 2015 showing a hypocellular bone marrow with preserved megakaryopoiesis (hematoxylin and eosin stain). (c) Myeloperoxidase staining revealed adequate numbers of myeloid cells. (d) Glycophorin C staining revealed a virtually absent erythropoiesis. (e) Biopsy section obtained on March 2017 revealed a severe hypocellular marrow (<5%) (hematoxylin and eosin stain). (g) Myeloperoxidase staining revealed a virtually absent myelopoiesis. (h) Glycophorin C staining revealed a virtually absent erythropoiesis. (b and f) In both biopsies, immunohistochemical stain for CD3 revealed a modest lymphoid component with interstitial distribution (CD3+).
