Surgical treatment of verrucous carcinoma of the bladder unassociated with bilharzial cystitis: case report and literature review.

Verrucous carcinoma of the bladder unassociated with bilharzial cystitis is rare with only 6 cases reported to date. Verrucous carcinoma of the bladder, like that involving the cervix, vagina, oral cavity, perineum and lower extremities, may invade surrounding structures but remain surgically curable. Although it is similar to condyloma acuminatum, verrucous carcinoma is considered malignant because of its invasive growth pattern and it should be treated accordingly. However, no evidence of metastases has been noted to date. To our knowledge we report the first case of extravesical extension of verrucous carcinoma of the bladder that was treated successfully by surgical removal.
