Periferal cystic hyperplasia of the prostate gland

Cystic transformation of the periferal prostate affecting at least 10 cm3 of tissue was found in 19 out of 300 consecutive prostatic glands at autopsy. The etiology is probably multifactorial and no correlation is found with nodular hyperplasia or carcinoma. Periferal cystic hyperplasia may be a cause of palpatoric enlargement of the prostate and thus may be a differential diagnostic possibility to nodular hyperplasia or cancer.
