Transitional cell carcinoma of fossa navicularis in a man with three other synchronous malignancies.
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.
