Rete-testis-Karzinom mit lymphogener Metastasierung

Cancers of the rete testis are uncommon and usually occur in the 6th or 7th decade of life. The prognosis is dreadful. Approx. 40% of the affected patients die within 1 year after diagnosis due to progression of the disease. The primary therapy is surgical. Until now there is no effective chemotherapy. In our case following primary inguinal orchiectomy and confirmation of the diagnosis, a radical retroperitoneal lymphadenectomy and wide local resection were performed. One positive lymph node was found and adjuvant radiotherapy was performed. In this case preoperative PET/CT was not helpful. For the last 3 years now the patient has been disease free. Since cancers of the rete testis are very rare and the literature is scarce, we would like to recommend the introduction of a national registry.
