In this image the columnar cells with cytoplasmic luminal 'snouts' are illustrated very clearly.
Columnar cell hyperplasia with atypia.
The columnar cell population represents the majority of the cells here - note the variability of nuclear morphology and the presence of nucleoli (red arrows). The blue arrows point to admixed myoepithelial cells which in this image have clear cytoplasm and small pyknotic nuclei (H&E x 40)
