Table. Clinical Details of Patients With Febrile Agranulocytosis Associated With Use of Cocaine Adulterated With Levamisole
Photographs of bone marrow aspirate (top) and trephine biopsy (bottom) from a patient with agranulocytosis and levamisole found in the urine.
Neutrophils and bands are almost completely absent. The abundance of granulocytic precursors suggests toxin-related impairment of granulopoiesis with reduction of neutrophil maturation. The remainder of the bone marrow shows normal heterogeneity. Top. Bone marrow aspirate (May-Grünwald–Giemsa stain). Bottom. Bone marrow trephine biopsy (hematoxylin–eosin stain).
