    Description / Table of Contents: Summary A survey is given of methods involving decalcification and paraffin embedding of iliac crest biopsy for osteological and haematological diagnostic procedures. In order to avoid shrinkage, loss of antigens, and fading of ferritin iron and enzymes, a fixative has been designed that is composed of an aqueous solution of calcium acetate (10–1 M), glutaraldehyde (0.5 %), and formaldehyde (1 %; CGF). CGF-fixated specimens are decalcified in an aqueous solution of 10 % di-sodium ethylene-diaminotetraacetate (EDTA) neutralized by tris[hydroxy]methyl-aminomethane and embedded in paraffin. Tissue prepared in this manner allows histochemical detection of naphthol AS-D chloroacetate esterase in the neutrophilic cell line and in tissue mast cells, tartrate-resistant acid phosphatase in hairy cells and certain other low malignant B-cell lymphomas, in Gaucher cells, and in osteoclasts, and a specific platelet esterase in megakaryocytes and leukaemic megakaryoblasts. A broad panel of antigens is well preserved. Beside haemosiderin, cytosolic ferritin can be detected by Perls' reaction in acute phase-stimulated macrophages. Emphasis is placed on the diagnostic impact of plasma cell siderosis and lysosomal sideroblastocytosis in haemochromatosis and in alcoholism respectively. A technique is presented to discriminate mineralized and non-mineralized bone even after decalcification.
    Notes: Zusammenfassung Beckenkammbioptische Untersuchungen erfordern eine problemorientierte histologische Bearbeitungstechnik. Alternativ stehen Verfahren der Kunststoffeinbettung unentkalkten Gewebes einer Paraffineinbettung nach Entkalkung gegenüber. Die Paraffineinbettung setzt die Fixierung in einer Lösung aus Kalziumazetat, Glutaraldehyd und Formaldehyd (KGF) sowie eine neutrale Chelatentkalkung voraus. Die KGF-Fixation vermeidet jegliche Hämolyse, bewirkt eine gute zelluläre Strukturerhaltung und garantiert den Nachweis von Ferritineisen in Markretikulumzellen. Die Unterscheidung von Ferritin- und Hämosiderineisen ist für die Differentialdiagnose von Anämien essentiell. Unter den extraphagozytären Eisenablagerungen verdienen lysosomale Siderosomen in Erythrozyten und Erythroblasten bei alkoholischer Dysmyelopoese sowie die Plasmazellsiderose bei Hämochromatose Beachtung. Eine breite Palette (immun)histochemischer Techniken wird tabellarisch dargestellt. Die Naphthol-AS-D-Chlorazetatesterase läßt sich in der neutrophilen granulozytopoetischen Zellreihe und Gewebsmastzellen darstellen und dient in einer speziellen Modifikation zur Darstellung mineralisierter Knochenstrukturen nach Entkalkung. Tartratresistente saure Phosphatase markiert Osteoklasten in unterschiedlichen Funktionszuständen, Gaucher-Zellen und bestimmte Lymphome. Als weiteres einbettungsresistentes Enzym wird erstmals die spezifische Plättchenesterase vorgestellt.

    Notes: Abstract We report a case in which an adult form of Niemann-Pick disease (type B of NPD) was associated with a rapidly progressive generalized AL amyloidosis of kappa type. Both diagnosis were made by biopsy, the NPD by bone marrow biopsy and fibroblast culture, the amyloidosis by liver biopsy. Malignant non-Hodgkin lymphoma was not found. The patient, a 67-year-old woman, died from hepatic coma subsequent to a progressive liver failure. We discuss possible relations between the lysosomal storage disease and the development and rapid progression of amyloidosis.
