Adrenal tissue collection
adrenal adenomas
PATHOLOGY, ADRENAL ADENOMA
Adrenal tissue was collected directly from surgery. Once the adrenal was removed, this was dissected into 5 mm serial slices by the surgeon or histopathologist. All adrenal adenomas were identified and 10–200 mg of tissue was removed from each APA and adjacent normal adrenal gland (AAG) for storage in separate tubes in RNAlater solution (AM7020; Invitrogen). Slices were sent to pathology for routine clinical hematoxylin and eosin staining and IHC.
