Cytobiologic and clinical aspects in a patient with chronic neutrophilic leukemia after thorotrast exposure.
A patient with fairly typical chronic neutrophilic leukemia, as represented by some two dozen such reported cases, had been given Thorotrast more than 20 years before. Typical myeloblastic crisis developed with remarkable terminal leukocytosis. Mature blood neutrophils had normal function with respect to phagocytosis, bacterial killing, metabolic activation, and chemotactic response. The number of cells producing colonies of neutrophils and monocytes in in vitro semisolid cultures was normal in the blood and increased in marrow. Colony size was smaller than is usually observed in normal patients or in typical patients with chronic myeloid leukemia. Termination in blast crisis, also seen in a few other patients with chronic neutrophilic leukemia, indicates that this is indeed a form of leukemia and not a "leukemoid" reaction of obscure cause. The differential diagnosis of extreme neutrophilia is discussed.
