71 surgically removed pituitary adenomas with amyloid deposits were studied by light microscopical and immunohistological means. In none of the adenomas was there a predominance of amyloid deposits.

Our results do not support either of the theories about the origin of amyloid--whether mesenchymal or produced by adenoma cells--in pituitary adenomas.
