or tumor,
tissue composed of cells that grow in an abnormal way. Normal tissue is growth-limited, i.e., cell reproduction is equal to cell death. Feedback controls limit cell division after a certain number of cells have developed, allowing for tissue repair

While the mean ID score for PIT-1-positive adenomas was significantly lower than gonadotroph and nonfunctioning adenomas (p = 0.001 and p = 0.0026, respectively), the difference between the latter two subtypes was not significant (p = 0.1908) as illustrated in Figure 3(c) and Table 3.
(12), 40 nonfunctioning adenomas were analyzed and no significant difference was observed in the immunohistochemical expression of ECAD between tumors with and without cavernous sinus invasion.
The development of sensitive and specific antisera and improvements in tissue fixation allow better antigen recognition and gonadotropic hormones are detected by antisera to [beta]-follicle-stimulating hormone and b-luteinizing hormone in many clinically nonfunctioning adenomas. The application of immunohistochemistry for transcription factors allows identification of cell lineage even in the absence of hormone immunoreactivity.
comparing VEGF in a series of adenomas composed of 77% nonfunctioning adenomas and only 4% of prolactinomas found the highest expression in nonfunctioning adenomas and GH producing adenomas [22].
