    Notes: Abstract  Angiosarcomas are rare malignant mesenchymal tumours, characterized morphologically by anastomosing vascular channels lined by atypical and proliferative active endothelial cells. An epithelioid cytomorphology of tumour cells is often seen focally in angiosarcoma, whereas purely epithelioid angiosarcomas are rare. Although angiosarcomas show a vascular differentiation they are almost never confined to pre-existing blood vessels. We describe three cases of intravascular epithelioid angiosarcoma arising in the carotid artery of a 60-year-old man, in the infrarenal part of the abdominal aorta and both renal arteries of a 69-year-old woman, and in the abdominal aorta of a 68-year-old man. In all cases malignant tumour tissue was found incidentally after disobliteration of thrombosed vessels. Histologically, purely epithelioid angiosarcoma composed of solid sheets of epithelioid tumour cells was seen; immunohistochemistry confirmed the endothelial differentiation of neoplastic cells. The reported cases show that angiosarcoma can occasionally arise within a pre-existing vessel.

    Description / Table of Contents: Zusammenfassung An der II. Chirurgischen Abteilung des AK Harburg wurden in 5 Jahren (1981–1985) 263 Patienten mit einem infrarenalen Bauchaortenaneurysma operiert. Im vorliegenden Film werden die Diagnostik beim Bauchaortenaneurysma, die Untersuchungstechnik und -taktik beim Hausarzt und in der Klinik vorgestellt sowie die Operation zweier Aneurysmen gezeigt. Postoperative Probleme, Risikofaktoren und Kontraindikationen zur Operation werden diskutiert.
    Notes: Summary At the 2nd Surgical Department of the Harburg General Hospital in Hamburg, Germany, 263 patients with infrarenal abdominal aortic aneurysms were operated on during a 5-year period from 1981 to 1985. The film demonstrates diagnostic procedures and evaluation techniques, as employed by the family physician and the clinician. Moreover, operations for two abdominal aneurysms are shown. Postoperative problems, risk factors, and contraindications against operative procedures are discussed.
