[Atypical hyperplasia of the prostate: coincidence with invasive carcinoma. A study of 69 prostatectomy preparations].
In a series of 69 prostatectomy specimens, including 62 invasive carcinomas, we studied the prevalence of atypical hyperplasia of small acinar, large acinar and cribriform type, diagnosed according to the criteria of J. Kovi, 1989. The study was performed on serial whole sections of 5 mm thick slices. As a result, the association of atypical large acinar hyperplasia with small acinar or cribriform atypical hyperplasia was significantly increased in cases with coincidental carcinoma. Furthermore, atypical cribriform hyperplasia was almost exclusively found in cases with cribriform or solid type of invasive carcinoma.
