Context: Surgical removal is the primary treatment option for pituitary adenomas. However, pituitary surgery is frequently incomplete because of invasion of extrasellar cerebral structures, notably, of the cavernous sinus. Our objective was to study the molecular basis of the cavernous sinus invasion by pituitary adenomas.Methods: We analyzed a tissue collection of 19 invasive pituitary adenomas with a sample from the intrasellar portion and a sample fro...

Context: Primary bilateral macronodular adrenal hyperplasia (PBMAH) with glucose-dependent insulinotropic polypeptide (GIP)-dependent CushingÂ’s syndrome is caused by ectopic expression of GIP receptor in the adrenal tissue. The bilateral nature of this adrenal disease suggests germline genetic predisposition. We aimed to identify the molecular driver event responsible for ectopic GIP receptor expression in PBMAH.Methods: We conducted an internationa...
