[Polyradicular neural syndrome in a patient with leukemic variant of malignant histiocytosis].

Malignant histiocytosis is rapidly progressive, fatal disorder characterised by systemic proliferation of abnormal histiocytic cells. We report a case of a 23-year old patient with leukaemia variant of malignant histiocytosis and nervous system involvement as polyradiculoneural syndrome. The leukaemia variant as well as nervous system involvement are extremely rare in malignant histiocytosis.
