The DCIS is predominantly cribriform, low grade(Van Nuys).
ER stain can highlight the clonal pattern in DCIS.

Breast - Atypical Intraductal papilloma / Papillary Neoplasm 100%
|
Immunostains required:
1.Actin to highlight myoepithelial cells in the papillary lesion
2.CK14 to assess intensity of staining of the ductal cells
If both are lacking / reduced, need to suspect DCIS involving intraductal papilloma.
