Microscopically, the cyst was lined by a mucinous epithelium that included basally located hyperchromatic nuclei and scattered Goblet cells consistent with an intestinal phenotype. c. The tumor that showed papillary formations and mild atypia was positive for cytokeratin 20 immunostain. d. The tumor cells were positive for CDX2 immunostain
