Transitional cell carcinoma of the fossa navicularis in a man with preexisting adenocarcinoma of the prostate

In this report we present a patient with a history of prostatic adenocarcinoma who was found to have a low-grade/ low-stage transitional cell carcinoma of the fossa navicularis. The patient underwent transurethral resection and at approximately 2 years of follow-up he has no evidence of tumor recurrence. Very limited follow-up data exist on which to base management decisions, and this report lends support to the use of transurethral resection alone as a means to treat low-grade/low-stage lesions.
