Case Report: Recurrent verrucous carcinoma of the urinary bladder after transurethral resection followed by intravesical mitomycin and a review of the literature

摘要

Verrucous carcinoma (VC) is a locally invasive, non-metastasising well differentiated variant of squamous cell carcinoma. It is very rare in the urinary bladder and mostly associated with schistosomiasis. It has a characteristic multilobular appearance with small surface projections on contrast cystogram. Owing to its bland cytology, it is a challenging diagnosis. We report a case of VC of the bladder—unrelated to schistosomiasis and involving the prostate—that recurred after transurethral resection of the tumour and prostate followed by six doses of intravesical mitomycin. To the best of our knowledge, no such case has been reported from Pakistan.
