Small cell neuroendocrine tumour of the bladder: a case report

Résumé

Neuroendocrine tumours of the bladder are rare, with an incidence reported at less than 1% of all bladder tumours. We report on a case of small cell neuroendocrine tumour in a 51-year-old male. The diagnosis was made after an initial resection of a bladder mass. He received four cycles of neoadjuvant chemotherapy resulting in a positive response initially, but was noted to have progression of disease prior to planed radical cystectomy.
