Morphological studies in malignant tumors of the peripheral nervous system (neurofibrosarcoma, malignant schwannoma, schwann cell sarcoma).

9 cases of malignant tumors of the peripheral nerve sheaths have been observed and their morphology including ultrastructures have been studied. 5 cases could be classified as neurofibrosarcomas, I as a Schwann cell sarcoma. Another cases may be grouped with the melaninproducing Schwann cell sarcomas and 2 cases with the "epitheloid Schwann cell sarcomas".

[Computertomographic and morphological findings in cerebral infarctions and intracerebral haematomas in identical sections (author's transl)].

The paper deals with computertomographic and morphological studies in patients who died suffering from brain ischaemia, haemorrhagical infarction and haemorrhages. These examinations were done in identical sections. Methodically computerized tomograms in living patients, postmortal tomograms, brain sections and macrosections were used.
