title: Intra-operative frozen section technique for pituitary adenomas.
abstract: Orange G-hematoxylin stains performed on frozen sections from the sella turcica had a diagnostic accuracy of over 90% when compared to permanent sections on the same tissue. This technique allows the pathologist to make an intra-operative contribution to the establishment of tumor margins in the selective removal of pituitary adenomas.
