    Description / Table of Contents: Zusammenfassung Bei einem Fall von chronischer lymphatischer Leukämie wurden histologische, cytochemische und elektronenmikroskopische Untersuchungen des Lymphknotens sowie Immunglobulinbestimmungen des Lymphknotenhomogenates und des Blutes durchgeführt. Die Immunglobulinbestimmungen deckten eine hochgradige IgM-Vermehrung im Lymphknoten bei IgM-Verminderung im Blut auf. Ein morphologisches Äquivalent dieser IgM-Vermehrung stellte die Ablagerung PAS-positiver Cytoplasmaeinschlüsse in den neoplastischen Lymphknotenzellen dar. Diese Einschlüsse waren in Ergastoplasmasäcken dieser Zellen lokalisiert. Im übrigen beherrschten ergastoplasmahaltige „sekretorische“ lymphatische Zellen ohne cytoplasmatische Einschlüsse das elektronenmikroskopische Bild. Es handelte sich also um ein IgM-bildendes B-Zellenlymphom vom sekretorischen Typ. Die unterbliebene Abgabe der Makroglobuline in das Blut ist als Sekretverhaltung zu deuten. Da das IgM als 8 S-IgM im Gewebe vorlag, nehmen wir an, daß hier eine Polymerisationsstörung der IgM-Untereinheiten zu dem 19 S-Pentamer bestand, als deren Folge die unterbliebene Sekretion von IgM ins Blut anzusehen ist.
    Notes: Summary A lymph node of a patient suffering from chronic lymphocytic leukemia was investigated using histological, cytochemical and electron microscopic techniques. The remaining lymph node tissue and the blood were also examined for their immunoglobulin content. The immunoglobulin analysis revealed an excessive increase of IgM in the lymph node, while there was a reduced serum IgM level. A morphological equivalent of the increased IgM was constituted by the deposit of PAS-positive cytoplasm inclusions, which were embedded in distended cisternae of the ergastoplasm of the neoplastic lymph node cells. “Secretory” lymphatic cells containing ergastoplasm without inclusion bodies otherwise dominated the electron microscopic picture. The existence of a B-cell lymphoma producing IgM of the secretory type is thus demonstrated. The lack of emission of IgM into the blood has to be interpreted as the result of a defect in the secretory mechanism. As the IgM was found in the form of 8 S-IgM in the tissue, it can be assumed that a disturbance of the polymerisation of the IgM-subunits into the 19 S-pentamer existed, the result of which was the absence of secretion of IgM into the blood.

    Notes: Summary Using the Kiel and the Rappaport classifications, a comparative histopathological analysis of 486 cases with non-Hodgkin lymphomas from a prospective study of the Kiel Lymphoma Study Group, still in progress, was performed. The greater part of Rappaport's classical lymphoma entities was found to be inhomogeneous and to include tumors of considerable prognostic heterogeneity, as shown by differences in actuarial survival. Some of the Kiel lymphoma entities have been identified in several lymphoma types of the Rappaport classification, indicating that “translation” of one scheme into the other is difficult or impossible. In addition, centrocytic lymphoma of the Kiel classification may not be homogeneous. On the whole, the Kiel classification appears to be superior to the original Rappaport classification in categorizing the various prognostically diverse types of non-Hodgkin lymphomas.

    Notes: Summary On the basis of the retrospective analysis of 405 patients, suggesting the clinical relevance of the Kiel classification of non-Hodgkin lymphomas (NHL), a prospective multicenter study was started on October 1st, 1975, by the Kiel Lymphoma Study Group in order to further clarify the clinical and prognostic features of the different lymphoma entities defined by this histopathologic scheme. Diagnostic protocol provides initial staging evaluation according to a modification of the Ann Arbor classification. Therapeutic approach is based on the hypothesis that, like Hodgkin's disease, NHL originate, at least in part, as localized lymphatic or extralymphatic tumors. Thus, extended field irradiation is performed in stages I and II (except for lymphoblastic lymphoma in children and young adults) whereas in the more advanced stages III and IV (except for stage III of centroblastic-centrocytic lymphoma) chemotherapy with additional radiotherapy is applied. Until June 1979, 815 patients entered the study (69.7% with NHL of low-grade malignancy). For the interim evaluation underlying the present and the other papers of this series data of 511 patients were available. Survival of patients with NHL of low-grade malignancy significantly exceeds that of patients with NHL of high-grade malignancy. NHL with good prognosis such as chronic lymphocytic leukaemia and centroblastic-centrocytic lymphoma can be differentiated from NHL with a poor course such as lymphoblastic and immunoblastic lymphomas. In addition, the existence of a third group with an intermediate prognosis comprising centrocytic and centroblastic lymphomas and, possibly, also LP immunocytoma is suggested. However, different initial slope of survival curves shows that this latter group of NHL is not homogeneous with regard to prognosis.

    Notes: Summary The use of intraoperative choledochoscopy represents a significant advance in biliary surgery. Flexible instruments are ideal for examining the intrahepatic bile ducts, while rigid instruments are best suited for the extrahepatic ductal system. The cystic duct stump may be occasionally used for access, but, as a rule, a supraduodenal choledochotomy is necessary. Our experience with 776 examinations is reported. A total of 348 patients (44.8%) had ductal stones. In 10 patients (2.8%), a stone was overlooked. Equivocal cholangiograms, ductal stones, and obstructive tumors constitute the most important indications for endoscopic examination.
