title: Malignant histiocytosis. The diagnosis based on chromosomal, immunologic and histiopathologic analysis.
abstract: A 38-year-old female suffered for several months from persistent fever without signs of infectious or immunologic disease. 57Co-bleomycin scintigraphy revealed abnormal concentration in the liver. Following a diagnostic laparotomy, the patient died from abdominal haemorrhage. Malignant cell infiltration was demonstrated in a biopsy from the liver. Histiocytic cells were demonstrated in a bone marrow smear obtained shortly before death. Investigation of cultured lymphocytes obtained from the patient the day before she died showed deficiency of T-lymphocytes. Investigations of chromosomes delineated several clones with polyploidi. The diagnosis of malignant histiocytosis was based on erythrophagocytosis, and immunologic and chromosomal aberrations. If malignant histiocytosis is the primary disease, a terminal stage of different diseases or a sign of complication secondary to immuno incompetence (e.g. virus infection) is an open question.
