title: Incidental carcinoma of the prostate in Japan: histological characteristics and tumor size.
abstract: The incidence of incidental carcinoma of the prostate in Japan is reported, and a retrospective study of 60 incidental carcinoma of the prostate is presented on the basis of tumor size and histological features. As the tumor progressed in size, there was a corresponding increase in its malignant potential. The survival rate according to tumor size and histological grade showed a significant difference between A1 (less than 10 mm diameter and low grade) and A2 (greater than or equal to 10 mm diameter or moderate to high-grade tumor).
