Zusammenfassung
Wir berichten uber den Fall eines 82jährigen Patienten mit einem malignen Mesenchymom. Der Tumor entsprang vom parietalen Peritoneum mit enger Beziehung zum Colon ascendens. Wie die Immunhistochemie zeigen konnte, bestand der Tumor aus einem großen liposarkomatösen und einem kleineren leiomyosarkomatösen Anteil. Soweit wir wissen, ist dies der erste Bericht uber ein malignes Mesenchymom dieser histologischen Zusammensetzung im paritealen Peritoneum. Der Tumor konnie chirurgisch radikal entfernt werden. In Übereinstimmung mit anderen Autoren glauben wir, daß maligne Mesenchymome aus primitiven mesenchymalen Zellen mit totipotenten Differenzierungs-möglichkeiten entstehen.
Summary
We report the case of an 82-year-old male patient with a malignant mesenchymoma. The tumor arose from the parietal peritoneum closely attached to the ascending colon. It consisted of a larger liposarcomatous and a smaller leiomyosarcomatous component which was demonstrated by immunohistochemistry. To our knowledge this is the first report of a malignant mesenchymoma of this histological composition originating from the parietal peritoneum. The tumor was completely removed surgically, which is the treatment of choice for such tumors. In agreement with other authors, we believe that malignant mesenchymomas arise from a primitive mesenchymal cell with the capacity for totipotent differentiation.
