Coagulating Gland - Dilation, Acinar

comment:
Acinar dilation is characterized by distension of glandular acini with abundant secretory product, reduction or loss of epithelial papillary folds, and flattening of the lining epithelium. Dilated acini may be distinguished by their turgid appearance, increased staining intensity of the retained secretion, and increased acinar size. This is likely an age-related change, and a causal association with chemical administration has not been established. Some pathologists do not diagnose the degree of dilation shown in Figure 1

recommendation:
If a diagnosis of acinar dilation is made for a degree of dilation as shown in Figure 1
