    Description / Table of Contents: Summary The findings of a 60 years old patient with chronic lymphocytic leukaemia, who died with the clinical signs of lymphosarcomatosis, are discussed. The morphological picture corresponds with chronic lymphocytic leukaemia. Sarcoma cells did not appear neither in peripheral blood nor in bone marrow in accordance with cytochemical investigations. Post mortal we could differentiate 2 types of cell infiltrations: in liver sections periportal infiltrations like in chronic lymphocytic leukaemia and in spleen circumscribed tumor nodules. The tumor cells showed polyploidy in accordance with Feulgenphotometric DNA estimations, whereas lymphoblasts and lymphocytes from bone marrow and peripheral blood were diploid, corresponding with findings in other cases of chronic lymphocytic leukaemia.
    Notes: Zusammenfassung Es wird über eine 60jährige Patientin mit chronisch lymphatischer Leukämie berichtet, bei der sich das Krankheitsbild nach 13/4jährigem Verlauf plötzlich akut änderte und der Tod unter dem klinischen Bild einer Lymphosarkomatose eintrat. Hämatologisch-morphologisch fand sich im peripheren Blutbild wie im Knochenmarkpunktat weiter das Bild einer chronischen Lymphadenose ohne morphologischzytochemische Hinweise für eine Ausschwemmung von Sarkomzellen. Pathologisch-anatomisch waren 2 Infiltrationstypen unterscheidbar: In der Leber periportale Infiltrate wie bei chronischer Lymphadenose, in der Milz umschriebene Tumorknoten mit einem morphologisch völlig andersartigen Zellbild. Nach feulgenphotometrischen DNS-Bestimmungen wiesen diese Tumorzellen cine Polyploidisierung und wahrscheinlich eine erhöhte Proliferationsaktivität auf, Befunde, die die lymphatischen Zellen des Knochenmarks in Übereinstimmung mit Befunden bei chronisch lymphatischen Leukämien vermissen ließen.

    Description / Table of Contents: Zusammenfassung Es wird über das Auftreten einer perimembranösen Glomerulonephritis bei 31 Patienten berichtet, die wegen verschiedener Grundleiden durchschnittlich 7 Monate lang Penicillamin (durchschnittlich 1 200 mg/Tag) erhalten hatten. Die perimembranöse Glomerulonephritis ging bei allen Patienten mit Proteinurie, bei 12 Patienten außerdem mit Hämaturie einher. Bei 8 Erkrankten entwickelte sich auch nach Absetzen der Therapie rasch, bei 12 allmählich ein nephrotisches Syndrom. Bei 5 Patienten mit nephrotischem Syndrom, die im Verlauf von 12 Monaten zweimal biopsiert werden konnten, war der Urin zur Zeit der 2. Biopsie eiweißfrei. Die für die perimembranöse Glomerulonephritis typischen Veränderungen an der Basalmembran der Glomerulumkapillaren mit subepithelialer bzw. intramembranöser Ablagerung von elektronendichten Depots hatten sich weitgehend zurückgebildet, wie durch vergleichende elektronenmikroskopische Untersuchungen nachgewiesen werden konnte.
    Notes: Summary This report includes 31 patients who developed a perimembranous glomerulonephritis generally 7 months after the onset of the treatment of various illnesses with D-Penicillamine. In all cases the patients had a proteinuria, associated with a hematuria in 12 cases. After the treatment was stopped 8 patients rapidly developed a nephrotic syndrome, while its onset was more gradual in 12 other patients. 5 patients initially with a nephrotic syndrome had no proteinuria at the time of a second biopsy made up to 12 months later. In these 5 cases the typical changes of perimembranous glomerulonephritis observed on electron microscopy were much reduced in the second biopsy.

    Description / Table of Contents: Summary The case of a 65 year-old female with an immunoblastic sarcoma of T cell type (reticulosarcoma) is reported. Post mortem tumor cell infiltrations with the typically histomorphological criteria of an immunoblastic sarcoma were found in the uterus, bone marrow and leptomeninges. With the aid of immunological markers the T cell type of this malignant lymphoma was diagnosed intra vitam on the basis of CSF cells. Until now, only one case of an immunoblastic sarcoma of the T cell type has been described in the literature.
    Notes: Zusammenfassung Es wird über ein immunoblastisches Sarkom vom T-Zell-Typ (Retikulosarkom) bei einer 65jährigen Frau berichtet. Bei der Obduktion fanden sich Tumorzellinfiltrate mit den typischen histomorphologischen Kriterien eines immunoblastischen Sarkoms im Uterus, im Knochenmark und in den Leptomeningen. Intra vitam wurde die Diagnose eines T-Zell-Lymphoms durch Anwendung immunologischer Marker an Zellen des Liquor cerebrospinalis gestellt. Soweit übersehbar, wurde bisher nur ein einziger Fall eines immunoblastischen Sarkoms vom T-Zell-Typ beschrieben.

    Notes: Summary The results of electron microscopic examination of renal biopsies from 3 patients with rheumatoid arthritis treated with penicillamine are presented. All 3 patients developed a nephrotic syndrome upon discontinuation of penicillamine therapy. When viewed with the electron microscope, segmental forms of perimembranous glomerulonephritis (Stages I–II of Ehrenreich and Churg) and glomerular renal amyloidosis Grade I–III were observed. In all three cases the nephrotic syndrome was considered to be due to the simultaneous occurrence of the two disease processes. In 2 cases perimembranous glomerulonephritis with immuno-complex-deposits was assumed to be the dominant factor in the causation of the disease, in the other case amyloidosis was the principle abnormality.

    Description / Table of Contents: Zusammenfassung Die immunhistologische Untersuchung von 123 Nierenbiopsien nicht-glomerulonephritischer Nierenerkrankungen ergab, da\ bei FÄllen mit maligner Nephrosklerose Immunglobulinablagerungen sehr viel hÄufiger vorkommen als bei der benignen Nephrosklerose. Dabei geht die primÄre maligne Nephrosklerose vorwiegend mit glomerulÄren Immunglobulinablagerungen einher. HÄufig wird ein positiver immunhistologischer Befund, auch bei der diabetischen Glomerulosklerose beobachtet, der überwiegend innerhalb der Glomeruli, z.T. jedoch auch in der tubulÄren Basalmembran und der Bowmanschen Kapsel nachzuweisen ist. Bei der glomerulÄren Amyloidose bestehen schollig-bandartige Ablagerungen, wobei Unterschiede zwischen FÄllen mit und ohne nephrotischem Syndrom nicht erkennbar sind. Im Hinblick auf eine eventuelle Immunpathogenese der untersuchten Krankheitsbilder kann aufgrund der vorliegenden Befunde die Möglichkeit eines derartigen Mechanismus, besonders für die primÄre maligne Nephrosklerose sowie für bestimmte glomerulÄre VerÄnderungen im Rahmen eines akuten Nierenversagens und einer Transplantatabsto\ung, diskutiert werden. Für die diabetische Glomerulosklerose (von Sonderformen mit perimembranösen LÄsionen abgesehen) und die glomerulÄre Amyloidose halten wir einen derartigen Mechanismus für nicht wahrscheinlich. Differenziert man die Krankheitsbilder nach dem Typ des Ablagerungsmusters, dann finden sich bei den nicht-glomerulonephritischen Nierenerkrankungen Befunde, die denen einer Immunkomplexerkrankung entsprechen, Bilder wie bei einer Antibasalmembranerkrankung fanden wir nicht. Typische charakteristische Ablagerungsmuster für die Krankheitsbilder ergaben sich nicht, so da\ eine grö\ere diagnostische Bedeutung der Immunhistologie im Rahmen nicht-glomerulonephritischer Nierenerkrankungen nicht zukommt.
    Notes: Summary Immunohistological study of 123 kidney biopsies of non-glomerulonephritic kidney diseases showed that deposits of immunoglobulins are found more often in cases of malignant than in cases of benign nephrosclerosis. Primary malignant nephrosclerosis is mostly associated with glomerular deposits of immunoglobulins. Positive immunohistological findings are frequent in cases of diabetic glomerulosclerosis, mainly within glomeruli, but also in tubular basement membranes and Bowman's capsule. In cases of glomerular amyloidosis we see cloudy-bandlike deposits, but are unable to differentiate cases with or without the nephrotic syndrome. If we consider an immunopathogenetic mechanism for the diseases discussed in terms of the present findings, it seems possible for primary malignant nephrosclerosis as well as for certain glomerular changes associated with acute renal failure or rejection of transplants. In diabetic glomerulosclerosis (apart from special forms with perimembranous lesions) and glomerular amyloidosis, we consider such a mechanism to be unlikely. By separating the non-glomerulonephritic diseases into different types of deposits we found pictures that correspond with immunocomplex diseases. Pictures resembling anti-basement membrane diseases have not been seen. Characteristic patterns of deposits were not found, thus immunohistology is without additional diagnostic value in the field of non-glomerulonephritic disease.

    Notes: Summary A study of 110 patients with membranoproliferative glomerulonephritis (MPGN) revealed that this disease appears in a simple form and in a lobular form. Both forms are characterized by a differently severe proliferation of mesangial cells and by a mostly extensiv thickening of the glomerular basement membrane. The proliferation of mesangial cells and thickening of the glomerular basement membrane is more severe in the lobular form of MPGN. Dense deposit lesions were observed in association with both the simple form and the lobular form of MGPN. An analysis of the morphological and clinical features of MPGN in patients with dense deposits in the glomerular capillary walls failed to indicate that dense deposits represent a unique disease entity.

    Notes: Summary From 166 renal biopsies of 153 patients who showed the dominating mesangial IgA deposits of “IgA-Nephropathy”, relationships were established between immunohistologic, histologic and clinical findings with the following results: 1. The immunohistologic picture of IgA-Nephropathy exhibits a broad histologic spectrum including cases with histologically normal findings as well as mesangioproliferative Gn with focal and diffuse crescents. Most often the morphologic changes are associated with a mild and moderately severe mesangioproliferative Gn. 2. According to the extent of the morphologic lesions no discrepancy between immunohistologic and histologic findings exists. Excluding a few cases with a focal accentuation of the histologic picture the histologic lesions as well as the immunofluorescence pattern are diffuse. 3. The immunohistologic picture of IgA-Nephropathy cannot be associated with uniform and characteristic clinical and morphologic pictures. Therefore, the predominant mesangial IgA deposits of the IgA-Nephropathy-type should not be regarded as a clinical — morphologic entity but rather as a specific immunohistologic symptom with possible different underlying pathomechanisms, probably controlled by a common genetically determined aberrant immune response with in consequence various morphologic reactions of different intensity and with a relatively favorable prognosis in most cases.
