Verrucous carcinoma of urinary bladder.
A seventy-five-year-old man with a four-month history of dysuria had a verrucous squamous carcinoma harbored within a bladder diverticulum. Whereas this low-grade malignancy occasionally develops in bilharzial specimens, its occurrence in schistosome egg-negative bladders is distinctly uncommon, having been the subject of only 1 previous case report.
