RESUMO

OBJECTIVES: To determine the prevalence of prostatic intraepithelial neoplasia (PIN) in surgical specimens and assess its relationship to adenocarcinoma. METHOD: 205 surgical specimens (191) transurethral resections, 6 open prostatectomies, 8 needle biopsies) reported at the University Department of Pathology, Colombo over 64 months were reviewed. RESULTS: There were 170 benign hyperplasias and 35 adenocarcinomas. PIN I was present in 22.92% PIN II in 5.36% and PIN III in 7.32% of the specimens. 8.51%, 27.27% and 93.3% PIN I, PIN II and III were associated with invasive adenocarcinoma. Nine cases (4.39%) had high grade PIN (PIN II & III) in the absence of adenocarcinoma. CONCLUSION: PIN II & III were strongly associated with coexistent carcinoma but PIN I was not. The finding of high grade PIN in surgical biopsies with no obvious adenocarcinoma warrants examination of all available tissue and deep sections.
