[Primary carcinoma of the male urethra: report of two cases].

Two cases of primary carcinoma of male urethra are reported. Case 1: A 31-year-old male, who complained of urethral bleeding, was admitted to our clinic in April, 1982. A rice size papillary tumor was found at the fossa navicularis in the glans, and resected by electric knife. Histologically, the tumor was well differentiated squamous cell carcinoma. Case 2: A 37-year-old man, who complained of urethral bleeding, was admitted to our clinic in July, 1985. A tumor was found at the fossa navicularis in the glans and resected. Histologically, the tumor was well differentiated squamous cell carcinoma confined to mucosa. These two cases have not shown any signs of recurrence. Including these cases, 135 cases of primary carcinoma of urethra in the literature in Japan are reviewed.
