Invasiveness of pituitary adenomas.
528 biopsies from 396 pituitary adenomas were re-examined by light microscopy and checked for invasion of neighbouring tissues. The overall invasion rate was 41.9%. Highly differentiated ACTH-cell adenomas were invasive in 24.1%, undifferentiated mucoid-cell adenomas in 66.7%. The histological type of invasion was influenced by the adenoma type and by the invaded tissue. There was no obvious correlation between the adenoma type and the invaded tissue.
