Although they can be grouped together for producing hormones and/or subunits that are glycoproteins, these tumors originate from distinctive cell types (gonadotrophes and thyrotrophes) that are only remotely related. Gonadotroph cell adenomas are among the commonest types of pituitary adenomas, corresponding to the majority of the so-called “nonfunctioning” or clinically silent adenomas, while thyrotroph cell adenomas are extremely rare and usually […]
