    Description / Table of Contents: Zusammenfassung Es wird über eine seit 11/2 Jahren chronisch-progrediente N. peronaeus-Parese bei einem 27jährigen Mann berichtet. Die operative Exploration stellte eine Druckschädigung des N. peronaeus communis fest, bedingt durch eine offenbar atraumatische Muskelhernie. Der Muskelbruch hatte Kastaniengröße und war am fibularen Kopf des M. gastrocnemius lokalisiert. Die Dekompression des Nervs erfolgte durch Reposition der prolabierten Muskelmasse und Verschluß der Fascienlücke. Als Ursache des Fasciendefektes wird eine konstitutionelle Bindegewebsschwäche für möglich erachtet.
    Notes: Summary A case of chronic progressive peroneal nerve palsy is reported. The surgical exploration revealed a compression of the common peroneal nerve obviously due to a muscular herniation of the gastrocnemius near the head of the fibula, measuring about 1 inch in diameter. Decompression was achieved by surgery in repositioning the muscular hernia and closing the fascial gap. Weakness of connective tissue is considered a possible cause of the fascial defect.

    Notes: Summary The results of combined tissue culture, ultrastructural and enzyme histochemical investigations carried out on a sympathetic ganglioneuroblastoma are reported.In vitro a vigorous sprouting of newly formed neuritic processes was observed a few days after explantation. The enzymatic reactions for acethylcholinesterase were positivein situ as well asin vitro. The tumor elements showed the ultrastructural characteristics of nerve cells with many microtubuli and filaments, plenty of ribosomes, well developed endoplasmic reticulum. Dense bodies, corresponding to neurosecretion granula (catecholamines) were also observed. Synaptic structures were missing. The results of these investigations confirm that this kind of tumor is different from so-called medulloblastoma.
