Figure 1 Multiple glands with high-grade prostatic intraepithelial neoplasia (HGPIN) on needle biopsy
Figure 1 | Multiple glands with high-grade prostatic intraepithelial neoplasia (HGPIN) on needle biopsy. HGPIN glands (arrows) are architecturally benign (large with papillary infolding) with nuclear atypia. Notably, HGPIN does not show an infiltrative growth pattern. The risk of cancer following HGPIN on prostate biopsy is ∼20–30%, which is not significantly higher than that following a benign biopsy.
