Spectrum of histological lesions in 185 consecutive prostatic specimens.

ABSTRACT

One hundred and eighty five consecutive prostate specimens were studied. The predominant lesion noted was benign prostatic hyperplasia (B.P.H.) (92.97%). The incidence of carcinoma was low, (7.02%). Conditions which can mimic and should be considered in the differential diagnosis of carcinoma, like basal cell hyperplasia, atypical hyperplasia and atrophy associated hyperplasia were noted in 10, 4 and 3 cases of B.P.H. respectively. None of these cases showed evidence of carcinoma. Corpora amylacea were noted in 38.91% of the cases of B.P.H. and were conspicuously absent in cases of carcinoma. Chronic prostatitis was frequently encountered (58%) and metaplastic changes were seen in 11% of the cases.
