Pathophysiology and treatment of subclinical Cushing's disease and pituitary silent corticotroph adenomas [Review].
Pituitary adrenocorticotropic hormone (ACTH)-secreting tumor presents with a variety of clinical features. We outlined the features of ACTH release and characteristics of corticotroph adenoma cells. We especially focused on the corticotroph adenomas in patients with no clinical features of Cushing's disease. Subclinical Cushing's disease is defined by ACTH-induced mild hypercortisolism without ...
متن کاملSilent corticotroph adenomas.
Silent corticotroph pituitary adenomas (SCA) are defined as pituitary adenomas showing positive staining for adrenocorticotrophic hormone in immunohistochemical studies, but not associated with perioperative clinical or laboratory features of hypercortisolaemia. They account for 1.1-6% of surgically removed pituitary adenomas. Currently, two distinct pathologic subtypes of SCA are recognised. T...
متن کاملSilent Crooke’s cell corticotroph adenoma of the pituitary gland presenting as delayed puberty
SUMMARY Corticotroph adenomas are extremely rare in children and adolescents. We present a 15-year-old boy who was investigated for delayed puberty (A1P2G1, bilateral testicular volumes of 3 mL each). There was no clinical or laboratory evidence suggestive of chronic illness, and the initial clinical impression was constitutional delay in puberty. Subsequently, MRI scan of the brain revealed th...
متن کاملAggressive silent corticotroph adenoma progressing to pituitary carcinoma: the role of temozolomide therapy.
Temozolomide (TMZ) has recently been recommended as a novel approach in the management of aggressive pituitary tumors. Herein, we present the case of a 43-year-old man with a 20-year history of silent subtype 2 pituitary corticotroph adenoma. Nine surgical resections and radiotherapy had failed to provide a cure. Morphological evaluation of the tumor revealed a mildly pleomorphic adenoma, the c...
متن کاملPITUITARY DEPENDENT CUSHING\'S SYNDROME IN IRAN
During a 5-year experience with 32 adrenal tumors with different basic problems in the Department of Endocrinology , Taleghani Hospital, 25 were found pituitary dependent Cushing's syndrome, "Cushing's disease." The treatment of patients with Cushing's disease depends on the presence or absence of pituitary tumor. Ifno pituitary tumor is demonstrated, irradiation can be given to the pituit...
