title: Malignant histiocytosis in a patient presenting with leukocytosis, eosinophilia, and lymph node granuloma.
abstract: A patient with malignant histiocytosis presented with a number of unusual features including fever, leukemoid reaction, and eosinophilia. Other confusing findings included lymph node biopsies which showed reactive changes, noncaseating granuloma, and atypical Reed-Sternberg cells. These features are compared with cases appearing in the literature. The course was rapidly progressive despite combination chemotherapy.
