“…Large cell carcinoma of the urinary bladder (LCCB) was first reported in 1986 [4] and since then 17 more cases have been described on the literature [5,6,7,8,9,10,11,12,13,14,15,16]. Because of the relative rarity of these tumors there is no standard approach for managing SCCB [17] or LCCB [13].…”

Introduction: Neuroendocrine carcinomas of the urinary bladder are relatively rare, accounting for less than 1% of all bladder carcinomas. These tumors can be divided into the more indolent typical or atypical carcinoid tumors and the aggressive small cell and large cell neuroendocrine carcinomas. Objective: To report 2 clinical cases of large cell neuroendocrine carcinoma of the bladder (LCCB) and to review the epidemiology, prognosis, and current treatment algorithms for patients with bladder small and large cell neuroendocrine carcinomas. Results: In both cases hematuria was the presenting symptom. One patient was submitted to partial cystectomy and the other to trans-urethral resection of the bladder tumor. The former patient died on the third month postoperatively. The latter patient had extensive liver metastasis at the time of diagnosis and died from acute liver failure on the 14th postoperative day. In review LCCB is associated with a more aggressive behavior and poorer prognosis than transitional cell bladder carcinoma. No standard approach exists. Surgery (transurethral ressection, partial cystectomy, radical cystectomy), chemotherapy and radiotherapy are current treatment modalities. Conclusion: LCCB is an aggressive tumor which usually presents itself in an advanced stage. Neoadjuvant chemotherapy with platinum regimen plus aggressive surgical approach should be the treatment of choice.
