Figure 5: Borderline/atypical
proliferative/low malignant potential mucinous tumor. There is a complex
intraglandular pattern which is a combination of focal papillary and
cribriform-like growth and tangential sectioning. This pattern does
not qualify for intraepithelial carcinoma by any of the proposed criteria
because there is insufficient nuclear atypia or true cribriform growth.
