Microcystic urothelial carcinoma of the bladder: A case report.

Microcystic variant of urothelial carcinoma was recently added to the World Health organization classification of transitional cell carcinoma. This variant is characterized by its aggressiveness explaining the low long-term survival rate of the patients. Larger studies are needed to determine the adequate treatment course. We present the case of a 71-year-old patient who was diagnosed with muscle invasive microcystic variant of urothelial carcinoma of the bladder and remained free of tumor recurrence two year after surgery.
