Abstract
Transitional cell carcinoma arising from the anterior portion of the male urethra is rare, with less than 10 cases reported in the literature. Our patient had a high-grade, highly invasive transitional cell carcinoma originating in the fossa navicularis and extending proximally along the corpus spongiosum, the corpora cavernosa, and blood and lymphatic vessels. In addition, the patient had a concurrent low-grade prostatic adenocarcinoma, a large basal cell carcinoma of the nose, and a squamous cell carcinoma of the penile skin. The previously reported cases are reviewed, with particular reference to the possible association of these tumors with human papillomavirus infection.
