    Notes: Summary The following malformations were observed in a human embryo of 28 mm crown-rump length obtained at operation for tubal rupture in a case of extrauterine pregnancy: 1. Secondary anophthalmia with dysplasia and in part aplasia of the diencephalon. Rudiments of both eyes and eyestalklike proliferations within the diencephalon. No lenses and on the left side only a palpebral fissure. Hypoplasia of the right telencephalic hemisphere and of the right side of diencephalon, mesencephalon and proximal parts of the medulla oblongata. Pseudotumorous proliferations in the diencephalon, in the alar plate of the medulla oblongata (protruding into the fourth ventricle) and in the arachnoid. Hypoplasia of the right internal, middle, and external ear. Dysplasia and in part aplasia of facial osseous elements (cebocephalia). 2. Proximal esophageal atresia with distal tracheoesophageal fistula. 3. A Fallot's tetralogy with right-sided aortic arch and regressive right-sided ductus arteriosus, tricuspid atresia, hypoplasia of the right ventricle with excessive hypertrophy of its wall, and hypoplasia of the pulmonary trunk. Single left superior vena cava and abnormal, semicircular course of the stems of both coronary arteries.

    Description / Table of Contents: Zusammenfassung In Biopsiepräparaten von chronischen Hepatitiden wurde die Penetration und Zerstörung von Hepatocyten durch Lymphocyten (aggressive emperipolese) beschrieben und quantitativ ermittelt. Bei den untersuchten 48 Fällen von chronisch-persistierender Hepatitis spielte die aggressive Emperipolese nur eine untergeordnete Rolle und fehlte in vielen Fällen gänzlich. Demgegenüber ist sie bei den 36 untersuchten Fällen von chronischaggressiver Hepatitis stets deutlich, mitunter sogar in erheblichem Ausmaß vorhanden. Die aggressive Emperipolese ist — neben den Mottenfraßnekrosen — ein morphologisches, im Leberstanzzylinder lichtmikroskopisch nachweisbares Substrat für den Prozeß der „self-perpetuation“ des chronisch-entzündlichen Geschehens und ein weiteres Kriterium für die Abgrenzung der beiden Haupttypen der chronischen Hepatitis.
    Notes: Summary The penetration and destruction of hepatocytes by lymphocytes (aggressive emperipolesis) has been described and examined quantitatively in biopsy specimens of chronic hepatitis. In 48 cases of chronic persistent hepatitis, the aggressive emperipolesis was rare and, obviously, not of great importance; sometimes there was no emperipolesis at all. In 36 cases of chronic aggressive hepatitis, however, emperipolesis was always evident, usually even to a very high extent. The aggressive emperipolesis — as well as the piecemeal necrosis — is a significant phenomenon which can be seen in the light microscope in liver biopsies and gives evidence to the fact that this chronic inflammatory process is a progressive one; furthermore, it is an additional criterion to differentiate the two main types of chronic hepatitis.
