A case of chronic neutrophilic leukaemia associated with multiple myeloma is reported. The patient had a 6 months history of bruising and weight loss, and showed mature neutrophilic leukocytosis, hepatosplenomegaly, high neutrophil alkaline phosphatase score, hyperuricaemia, neutrophils with pseudotoxic granulation and scarce Döhle bodies; moreover, a monoclonal IgG lambda was detected amounting 57.3 g/L. The bone marrow was grossly hypercellular with marked myeloid hyperplasia and aggregates of immature plasma cells. After treatment during 1 year with melphalan and prednisone she is well, although persisting with neutrophilic leukocytosis, slight splenomegaly, and the monoclonal IgG decreased to 25.8 g/L.
We have reported a case of phenytoin-induced hemocytophagic histiocytosis indistinguishable on clinical and histopathologic grounds from malignant histiocytosis. We emphasize the need to investigate for microbiologic causes and drug ingestion, even if the diagnosis of malignant histiocytosis is plausible. We think that reactive and malignant histiocytosis are not really two distinct entities with different etiologies, but a continuum of host responses to several insults with different degrees of aggressiveness depending on the host immune status.
