Figure 1. Bone marrow biopsy revealed a hypercellular marrow with trilineage hematopoiesis. (A) Hematoxylin and eosin staining (magnification ×10). Immunohistochemistry studies show (B) decreased erythrocytosis by CD71 (×10) that are primarily erythrocyte precursors by (C) E-cadherin (×10), indicating minimal maturing erythroid lineage present beyond erythrocyte precursors. No evidence of melanoma by (D) Melan-A (×10), and (E) SOX10 (×10).
