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\u2014unrelated to schistosomiasis and involving the prostate\u2014that 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.<\/jats:p>","DOI":"10.1136\/bcr-2016-216146","type":"journal-article","created":{"date-parts":[[2016,6,15]],"date-time":"2016-06-15T14:26:46Z","timestamp":1466000806000},"page":"bcr2016216146","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Recurrent verrucous carcinoma of the urinary bladder after transurethral resection followed by intravesical mitomycin, and a review of the literature"],"prefix":"10.1136","volume":"2016","author":[{"given":"Masroor","family":"Hassan","sequence":"first","affiliation":[{"name":"Department of Pathology, Shifa International Hospital Islamabad, Islamabad, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asim","family":"Qureshi","sequence":"additional","affiliation":[{"name":"Department of Pathology, Shifa International Hospital Islamabad, Islamabad, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Humaira","family":"Nasir","sequence":"additional","affiliation":[{"name":"Department of Pathology, Shifa International Hospital Islamabad, Islamabad, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2016,6,15]]},"reference":[{"key":"2025082701485322000_2016.jun15_1.bcr2016216146.1","first-page":"670","article-title":"Verrucous carcinoma of the oral cavity","volume":"23","author":"Ackerman","year":"1948","journal-title":"Surgery"},{"key":"2025082701485322000_2016.jun15_1.bcr2016216146.2","doi-asserted-by":"publisher","DOI":"10.1007\/s12105-014-0551-7"},{"key":"2025082701485322000_2016.jun15_1.bcr2016216146.3","unstructured":"Velazquez EF , Sanchez DF , Barreto JE , et al .
