Informations about the disease
Pituitary adenomas (PAs) are common lesions in adults, occurring in 15-20% of radiologic findings. On imaging in children, these tumors are rare (0.2%). Although most PAs identified are incidental findings with no need for intervention, some are clinically relevant, because they secrete hormones or cause symptoms by compression or invasion of surrounding tissue. The etiology of PAs is diverse, with no known genetic causes for more than half of the PAs. In certain cases, germline or somatic genetic defects are associated with the development of PAs. Defined as a (distant) metastasis of a PA, pituitary carcinoma (PC) is a rare form of malignant intracranial neoplasm. The incidence of PC is low, with only 0.1-0.2% of PAs developing into PCs; the prognosis remains very poor. The lack of efficacy of current therapies is largely due to the limited understanding of the molecular pathogenesis of PAs and their malignant transformation into PCs. The DNA diagnostic yield is probably comparatively low and currently unknown overall, so that a clinical diagnosis can by no means be ruled out by a negative molecular genetic result.
