Abstract:
Transitional cell carcinoma is the most common type of bladder cancer in the United States. This case report discusses the finding of primary bladder carcinoid tumor (also called well-differentiated neuroendocrine tumor) in a woman with gross hematuria. With only 15-20 reported cases, primary bladder carcinoid is rare and the approach to treatment is unclear. There have been two muscle-invasive cases reported which required more extensive treatment plans. The patient presented in this case underwent complete transurethral resection of the tumor with the recommendation of surveillance cystoscopy every 3 months.
