[Verrucous epidermoid carcinoma of the bladder unrelated to schistosomiasis].
The authors report two cases of papillomatous squamous carcinoma of the bladder unrelated to schistosomiasis. Both patients were treated by endoscopic resection. The staging assessment comprised thoraco-abdominopelvic computed tomography. A papillomatous squamous carcinoma of the bladder was detected in both cases: one was classified as pT2 G1 N0 M0 and the other as pT1 G1 N0 M0. Recurrence was rapidly observed, at the first follow-up cystoscopy. The tumour initially classified as pT1 subsequently underwent transformation to sarcomatoid carcinoma with peritoneal metastases. Papillomatous squamous carcinoma of the bladder, a rare squamous cell carcinoma, is a well differentiated tumour with an exclusively local and regional development. The prognosis is determined by the degree of tumour invasion, with a high local recurrence rate. The prognosis of invasive tumours is identical to that of conventional squamous cell carcinoma. Therapeutic management is poorly defined, but the only curative treatment appears to be radical cystectomy.
