    Description / Table of Contents: Zusammenfassung Eine heterotope Knochenneubildung in malignen Tumoren oder deren Metastasen ist extrem selten. Bei einem 60jährigen Patienten zeigten multiple Muskelmetastasen eines Bronchialcarcinoms (Adenocarcinoms) eine ausgedehnte Verknöcherung. Auf Grund der histologischen Untersuchungsbefunde wird der Mechanismus der Knochenneubildung im Rahmen maligner Geschwülste diskutiert. Danach induzieren die Tumorzellen eine Proliferation des ortsständigen Mesenchyms mit Ausdifferenzierung der Mesenchymzellen zu Osteoblasten.
    Notes: Summary The formation of heterotopic bone tissue in malignant tumors or in their metastases is extremely rare. In a 60 years old male patient with bronchogenic carcinoma (adenocarcinoma) extensive bone formation was observed within multiple metastases in the skeletal muscles. On the basis of the microscopic findings, the mechanism of bone formation by malignant tumors is discussed. Obviously, proliferation of local mesenchymal tissue and differentiation of mesenchymal cells to osteoblasts is induced by the tumor cells.

    Leiomyomatosis peritonealis disseminata (1975)

    Description / Table of Contents: Zusammenfassung Es wird über einen Fall einer Leiomyomatosis peritonealis disseminata berichtet. Hierbei handelt es sich um multiple multizentrisch entstandene benigne Leiomyome unter dem Peritoneum. Da sie meistens im Verlauf einer Schwangerschaft auftreten und sich danach weitgehend zurückbilden, ist eine hormonelle Induktion des Tumorwachstums wahrscheinlich. Wegen der guten Prognose darf diese Krankheit nicht mit einem metastasierenden Leiomyosarkom verwechselt werden, damit inadäquate schwerwiegende therapeutische Maßnahmen vermieden werden.
    Notes: Summary Report of a case of disseminated peritoneal leiomyomatosis which is characterized by the occurrence of multiple benign leiomyomas of multicentric origin below the peritoneum. Usually they appear in the course of pregnancy and are prone to regress after delivery. Therefore a hormonal induction appears probably. In regard of the favourable prognosis this lesion must not be mistaken for a metastasizing leiomyosarcoma in order to avoid inadequate serious therapeutic measures.

    Notes: Summary Seven cases are reported that initially presented on endoscopic examination as duodenal polyps originating from islands of gastric mucosa within the duodenal bulb. Microscopic examination revealed mucosal cysts (MC), focal foveolar hyperplasia (FFH), and hyperplastic polyp (HPP). These lesions must be added to the list of neoplastic and tumorlike lesions of the duodenum that may endoscopically present as polyps.
