Synopsis
enlarged acini
dilated acini
globoid appearance of the dilated acini
dilated acini contain secretions
dilated acini are lined by cells with rounded nuclei with
an increased nuclear to cytoplasmic ratio
The acini are lined by several layers of luminal epithelial cells with loss of a polar arrangement.
myoepithelial cells are present, but not prominent.
Apocrine snouts are observed in most acini.
