Fig. 2. (A) Peripheral blood smear exhibits dominantly abundant nature of segmented and band form neutrophils with all stages of neutrophil precursors including promyelocytes, myelocyte and metamyelocyte. (B) Bone marrow biopsy reveals hypercellularity of cells and red marrow with dominant number of neutrophilic granulocytes bearing normal maturation. Myelobastic cells are less than 5% on the captured microscopic field. (C) Scanning magnification of the skin biopsy revealed diffuse infiltration of inhomogenous neutrophils with pustular formation (H&E, ×40). (D) Higher magnification reveals variable sizes and shapes of both the nucleus and the cells with characteristics (H&E, ×400). (E) Both immature and mature neutrophilic components are shown with low degree of atypia in size and shapes (H&E, ×400). (F) Positive immunohistochemical staining result to myeloperoxidase stain is observed (MPO, ×200).
