Combined gangliocytoma and non-functioning pituitary adenoma of the pituitary gland

摘要

The co-existence of neural tissue and pituitary adenoma in the sella turcica is very rare. To date, no more than 75 cases have been reported.They often present with hypersecretion of growth hormone (GH), prolactin and adrenocorticotrophic hormone. Few sporadic cases have been described in the literature with the simultaneous presence of non-functioning adenomatous cells and ganglion cells.We report a case of this tumor type and propose our hypothesis about the origin of this combined tumor.
