Pathology Testing for Pituitary Disorders

The OHSU Northwest Pituitary Center has two board-certified neuropathologists who examine tissue from more than 1,000 cases per year, including 350 muscle biopsies, 450 brain tumors, more than 100 pituitary surgery cases and 150 outside consultations.

Our specialists examine a patient's pathology material along with clinical, radiologic and laboratory data from OHSU's databases. Laboratory tests available for diagnostic analysis include enzyme histochemistry, immunohistochemistry, cytogenetics, molecular pathology and ultrastructural analysis. Processing includes routine staining, special tissue stains, immunohistochemistry for pituitary hormones, proliferative indexing, molecular markers and electron microscopy on selected cases. All tests are carried out in specialized laboratories by dedicated technicians who are experienced in processing neural tissue with rigidly implemented quality assurance strategies.
