Abstract:
Primary large cell neuroendocrine carcinomas of the urinary bladder are extremely rare. To date, only six cases of large cell neuroendocrine carcinoma have been reported. We present a case of a 19-year-old man who presented with gross hematuria and who was subsequently found to have a solitary tumor on the dome of the urinary bladder. The patient underwent transurethral resection of the bladder tumor for histological confirmation. A diagnosis of large cell neuroendocrine carcinoma was made based upon immunohistochemical reactivity for synaptophysin and CD56. Based on the pathologic diagnosis, he subsequently had a partial cystectomy. Histologically, the tumor penetrated the perivesical fat. It has now been 6 months since the surgery, and the patient is preparing to receive his 5th cycle of chemotherapy. There is no evidence of tumor recurrence or metastasis.
