atypical small acinar proliferation


atypical small acinar proliferation (prostate)

A small prostate acinus or acini with abnormal or atypical glands that have insufficient cytological or architectural atypia for a definitive diagnosis of cancer. ASAPs are seen in ±5.5% of patients undergoing needle biopsies of the prostate, in whom cancer is identified in 40–50% on subsequent biopsy.
 
Management
ASAP is probably best managed with active surveillance.
