Figure 7. Photomicrographs of the: A – Spleen with foci of extramedullary hematopoiesis and lipid-laden macrophages; B – dura mater with small area of epidural hemorrhage (H&E, 20X) and in C – scattered hemosiderin-laden macrophages(H&E, 100X; green arrowheads); D – within the hemorrhagic area, numerous erythroid precursors, megakaryocytes, and other immature hematolymphoid cells are present, consistent with trilineage extramedullary hematopoiesis (H&E, 400X).
