A Rare Case of the Urinary Bladder: Small Cell Carcinoma

Small cell carcinoma of the bladder is a very rare tumor accounting for less than 1% of all bladder cancers (1). It is much aggressive than the commonly seen types of cancers of the bladder and urothelial carcinoma and is associated with poor prognosis. Clinically, it has similarities with urothelial carcinoma. Patients with small cell carcinoma of the bladder typically present with macroscopic hematuria and rarely with signs of bladder irritation. Additionally, rarely, there may be signs of abdominal pain and urinary system obstruction. Although there has not been a consensus on the treatment because of its rarity, multidisciplinary approach, including radical cystectomy (RC), chemotherapy and radiation therapy, is recommended to increase the chance of cure and life expectancy.
