[Contribution to the formal pathogenesis of the classical seminoma. Early diagnosis from testicular biopsies?].

13 cases of seminoma of the testes were investigated in detail by means of light microscopy using paraffin and semithin sections. Paraffin sections were the basis for diagnosis, therapy, and prognosis. In semithin sectins, even individual seminoma cells within the seminiferous tubules were recognized by characteristic cytological features. In semithin sections also the development of the solid tumor from intratubular seminoma cells was elucidated. On the basis of our findings, the following concept of seminoma spread may be advanced: intratubular seminoma cells invade the lamina propria and gain access to to the interstitial tissue. Subsequent to the migration of seminoma cells, the tubules are smaller in diameter and contain only Sertoli cells. The seminoma cells in the interstitial tissue increase in number and build up the solid tumor.

[Histomorphology of the sacroiliac joint in ankylosing spondylitis and relevance to treatment (author's transl)].

The sacro-iliac joint of a patient who had been ill with ankylosing spondylitis for half a year was investigated histologically at necropsy. Two basic histological phenomena were apparent: inflammation and aggressive proliferating chondroid metaplasia at the chondro-osseous junction and in the subchondrium. Joint cartilage degeneration, joint cartilage fusion, capsule ossification and subchondral bone apposition were observed as epiphenomena at the sacro-iliac joint. Both basic morphological phenomena are due to the same cause which has not yet been clarified. They progress independently of each other with varying intensity. This assumption explains differing opinions and the relation of inflammation and pathological ossification of the skeletal axis as well as the unsatisfactory objective results of treatment. Only a combination therapy directed against both morphological basic phenomena will result in an objective therapeutic success and not only in a symptomatic improvement of ankylosing spondylitis.
