The article titled “Angiogenesis in Pituitary Adenomas: Human Studies and New Mutant Mouse Models” [1] reused wording from a book chapter published the same year by the same author group, “Prolactinomas: Role of VEGF, FGF-2 and CD31” in Tumors of the Central Nervous System [2], which was not cited. The review brought together the results of the authors’ previous experimental work on angiogenesis and pituitary adenomas in the context of the literature.
