Zusammenfassung

Die Keimstrang/Stromatumoren sind neben den Keimzelltumoren die wesentlichen endokrinen Tumoren des Hodens. Hinzu kommt das primäre Karzinoid, dessen Beziehung zu den Teratomen aber bis heute unklar ist. Stromatumoren sind insgesamt sehr selten, endokrin aktiv sind mindestens 10 bis 20%. Unter den Stromatumoren sind praktisch lediglich Leydig-Zell-Tumoren und Sertoli-Zell-Tumoren von Bedeutung. Endokrine Störungen gehen meist von den Leydig-Zell-Tumoren aus (Gynäkomastie, Pubertas praecox), sie sind bei den übrigen Stromatumoren weniger häufig, können aber grundsätzlich vorkommen. Der großzellige kalzifizierende Sertoli-Zell-Tumor ist meist Teil einer übergeordneten Störung (z. B. Peutz-Jeghers-Syndrom). Für die immunhistologische Charakterisierung von Bedeutung sind Inhibin, Calretinin, Zytokeratine, Melan-A, CD-99, Proliferationsmarker, der Androgenrezeptor und p53. Konventionelle Morphologie und immunhistologisches Färbemuster überlappen sich, unklare Fälle sollten deshalb grundsätzlich spezialisierten Zentren zugeleitet werden.

Abstract

The most characteristic endocrine tumours of the testis are germ cell tumours and sex cord/gonadal stromal tumours. They include the primary carcinoid, the relation of which to teratomas is still unclear. In general, gonadal stromal tumours are rare, however, endocrine activity occurs in at least 10%–20%. Among gonadal stromal tumours, only Leydig cell tumours and Sertoli cell tumours are of practical importance. Endocrine disorders are mostly related to Leydig cell tumours (gynaecomastia, pubertas praecox). Although less frequent than the other gonadal stromal tumours, they can, in principle, occur. The large cell calcifying Sertoli cell tumour occurs in association with other complex disorders (i.e. Peutz-Jeghers syndrome). Valuable markers are: inhibin, calretinin, cytokeratin, melan-A, CD-99, Ki-67, androgen receptor and p53. As the conventional morphology and immunohistological markers frequently overlap, unclear cases should be referred to specialised centres.
