Mine didn't give a size either, but did say large, I don't have a clue to what the "involving X % of needle core" mean that was on each sample taken? I would guess the percent of core sample that was cancer tissue since a percent is on every sample listed. But does it mean the whole percent of needle core sample was cribriform or part of the core sample was cribriform on the 2 samples that had cribriform? Example of one core below:
Prostatic adenocarcinoma Gleason score 4+3=7 (Grade group 3) in 1 of 1 core, involving 60% of needle core tissue.
Large cribriform glands present

Didn't give size, I am think it doesn't mean the whole percent listed as it say cribriform was present?
