title: [Iliac crest biopsy findings in malignant non-Hodgkin lymphoma].
abstract: Issuing from the clinico-prognostic importance of the classification after Kiel of the malignant non-Hodgkin-lymphomas the results of the attempt of a reclassification of positive bioptic findings of the iliac crest judged according to the former German nomenclature are described and discussed after the Kiel classification. In the total material of 725 biopsies 76 positive findings of the marrow were stated in malignant non-Hodgkin-lymphomas, which at 67.1% consist of such with a lower and at 32.9% of such with a high degree of malignity, in which case a strong decrease of the formerly diagnosed CLL is to be seen after reclassification, whereas the immunocytomas render the by far largest proportion. The former malignant reticuloses disappear per definitionem after reclassification and, as it was expected, are broadly distributed. In 112 biopsies which were performed on account of the suspicion of an affection of the marrow in malignant non-Hodgkin-lymphomas the 76 positive findings correspond to a frequency of 67.9%, which, however, must critically be judged, since the case in question are very selected numbers of patients.
