Abstract
This was the case of a 64-year-old man with osteosarcoma. The biopsy yielded undifferentiated tumor without bone or cartilage formation. Because of high age of the patient and radiological changes present, a metastatic carcinoma was suspected. However, no primary could be found. Autopsy revealed an osteosarcoma in the region of the hip joint with alternating formation of tumor cartilage and tumor bone. There were also undifferentiated portions of “endocrine osteosarcoma,” simulating carcinoma. In spite of extensive skeletal involvement and pulmonary metastases-and high age-no evidence of morbus Paget of bone as possible preneoplastic disease was found. Es wird über ein Osteosarkom bei einem 64jährigen Mann berichtet, bei dem aufgrund des Biopsiebefundes mit undifferenzierten Tumoranteilen sowie auch wegen des Alters and des Röntgenbefundes an Karzinommetastasen im Knochen gedacht wurde. Ein „Primartumor” konnte jedoch nicht gefunden werden. Die Autopsie ergab ein z.T undifferenziertes karzinomähnliches, daneben jedoch deutlich tumor-, knochen- and knorpelbildendes Osteosarkom im Bereich des linken Hüftgelenks mit multiples Skelettund Lungenmetastasen, ohne daß dabei trotz hohem Alter and ausgedehnter Ausbreitung des Sarkoms ein M. Paget als Vorerkrankung oder Risikofaktor nachgewiesen werden konnte.Keywords
