MORPHOLOGICAL CHARACTERISTICS AND DIFFERENTIAL DIAGNOSIS OF UROTHELIAL BLADDER CARCINOMAS: A LITERATURE REVIEW

Abstract

Cancer of the bladder occupies the seventh place among the most common malignancies in the world and also represents the most frequent malignancy of the urinary system, characterized by a tendency to relapse and a specific course of development. Urothelial carcinoma (UC) of the bladder is three times more common in men. By the age of 40, the tumor is sporadic. After the 5th decade, however, the incidence increased sharply. The complications caused by UC worsen the quality of life of patients. UC is the second most common neoplasm of the urogenital system after prostate cancer and is one of the biggest challenges that the World Health Organization (WHO) faces.
