A reticulin stain can often reveal small quantities of anterior gland that were not otherwise suspected to be present; these usually occur at the edges of adenoma tissue fragments, and recognizing that these are present can avoid miscalling entrapped normal pituicytes with their varied immunoreactivity patterns as part of the adenoma.
