Talk:Atypical small acinar proliferation

Suspicious for carcinoma

K. PROSTATE, LEFT MEDIAL INFERIOR, BIOPSY:
- SUSPICIOUS FOR ADENOCARCINOMA;
- HIGH-GRADE PROSTATIC INTRAEPITHELIAL NEOPLASIA;
- SEE COMMENT.

COMMENT:
Part K has patchy basal cells in atypical foamy glands with AMACR positivity. This may
represent high-grade prostatic intraepithelial neoplasia (HGPIN) with outpouchings;
however, carcinoma cannot be excluded. Close follow-up and a re-biopsy is suggested. This
part was reviewed internally.
