From: Mast cell leukemia associated with undefined morphology and chronic basophilic leukemia
Demonstrating basophils at various stages of maturation,giant binuclear basophilic metamyelocyte, aggregates of mast cells with mixed black and orange color round cytoplasmic granules and Pelger-Huёt anomalies in (a) (Wright’s stain, ×100). Showing diffuse granular staining by peroxidase stain in peroxidase positive basophils and absence of staining in aggregates of cells that representing myeloperoxidase negative mast cells in the BM in (b) (Peroxidase stain, ×100).
