title: Malignant histiocytosis --- a case report.
abstract: Malignant Histiocytosis (MH) is an uncommon disorder characterised by systemic tissue infiltration of atypical histiocytes and its precursors. The clinical features included fever with weight loss, hepatosplenomegaly and pancytopenia. The antemortem pathology of the lymph node and bone marrow were non-specific and non-diagnostic. However, at autopsy, there were florid pathological changes of malignant histiocytosis. This case illustrates the difficulty of making a definite antemortem diagnosis of this rare malignant condition and the terminology, aetiology and pathological features are discussed.
