Abstract
A 66-year-old man was operated upon for a solid tumour in the spermatic cord. The tumour consisted of epithelioid cell granulomatous inflammation. Tubercle bacilli could not be seen in specimens stained by the Ziehl-Neelsen method but could be demonstrated by fluorescence microscopy. The patient had been operated upon twice earlier, 8 and 4 years ago, for hypertrophy of the prostate. Reexamination of specimens taken from his prostate on these occasions imply that even then he had tuberculosis of the prostate. The ductus deferens was free from inflammatory changes. It is likely that spread of infection from the prostate had occurred via the lymphatics.
