The case reported here is one of granulomatous prostatitis from which both Mycobacterium kansasii and M fortuitum were isolated by culture.

During this time, he refused cystoscopic and roentgenographic studies.In September 1975, during one of his routine visits, an area of slightly increased induration was palpated in the right lobe of the prostate, and by February 1976, this nodule had increased in size. The nodule was discrete, was 4 to 5 mm in diameter,
