[Epididymal tumors (author's transl)].

Six cases of benign primary epididymal tumor have been investigated in our patients. The tumor size fluctuated between 3 and 35 mm in diameter. Frequency, histology and medical development are described. The majority of epididymal tumors (53%) is comprised of so-called adenomatoid tumors of benign nature and their histogenesis is being discussed. The difficulties of differential diagnosis are pointed out. Since malignity exists in 26% of the cases, the surgical exposure and diagnosis by frozen section is being postulated, when suspicion of epididymal tumor becomes evident.
