(A) Invasive tumor nests with poorly-formed, small to intermediate-sized glandular spaces lacking intervening stroma. (B) Invasive fused tumor glands of intermediate-sized glandular spaces with extracellular mucin, lacking intervening stroma or having very thin stroma in limited areas between glandular spaces. (C) Invasive tumor nests with poorly-formed, intermediate-sized glandular spaces with back-to-back formations. (D) Invasive tumor nests with a few poorly-formed, small-sized glandular spaces with “cookie-cutter” patterns.
