Diagnosis: Adenocarcinoma with Gleason grade 4, Gleason grade 5, and extraprostatic extension.  

            Comments: Gleason grade 4 is due to fused glands. Gleason grade 5 due to cribriform arrangement with comedonecrosis (presence of few nuclear debris in eosinophilic secretion). An important finding in this case that must be reported is extraprostatic extension due to adipose tissue invasion.
