The third case of a culturally and histologically proven candidosis of the prostate in the world literature available to us is reported. Autopsy of a 59-year-old man with metastasizing bronchial carcinoma as predisposing primary disease revealed a local candidosis of the prostate in the left lobe of the prostate, without evidence of a Candida sepsis. Parallel and different aspects in comparison with the other two cases are described.
