Clear cell adenocarcinoma of the male urethra.

摘要

We present a rare case of clear cell adenocarcinoma of the male urethra. These tumors are usually presented with hematuria, obstructive voiding symptoms or urinary retention. Histologically, they display tubulocystic, tubular, papillary or diffuse patterns with clear and hobnail cells. The present case of this rare disease emphasizes the aggressive nature of urethral clear cell adenocarcinoma in males.
