RT-PCR analysis of corticotroph-associated genes expression in carcinoid tumours in the ectopic-ACTH syndrome.
OBJECTIVE ACTH is frequently produced in non-pituitary tumours, leading to the ectopic-ACTH syndrome, but the molecular mechanisms of its expression remain obscure. This study was aimed at understanding the transcription mechanisms of the ACTH-precursor gene in carcinoid tumours of the lung or thymus. DESIGN Transcripts coding for a series of corticotroph-associated transcription factor genes...
متن کامل[Ectopic ACTH syndrome].
Cushing症 候群 は慢性的なコルチゾール過剰症であ り,放 置すると脳血管障害,糖 尿病,感 染症などで死 亡する.し たがって,適 切な診断 と治療が重要である. 表1に 示すように,ACTH依 存性Cushing症 候群 に は脳下垂体のACTH産 生腫によるGushing病 と異所 性ACTH症 候群があ り,ACTH非 依存性Cushing 症候群 には副腎原発性病変,医 原性 によるCushing症 候群がある.中 で もGushing病 と異所性ACTH症 候 群の鑑別 は治療法の選択 と関連 して重要である.我 々 が経験 した異所性ACTH症 候群を紹介する. 【症例】64歳,女 性.1993年 頃か ら顔面,下 腿の浮 腫,し びれ感 と全身の疼痛(肩 甲部,胸 部,腰 背部) を自覚するようになったため某院に入院した.糖 尿病, 高血圧,骨 粗鬆症 と診断さ...
متن کاملEctopic ACTH syndrome.
Ectopic adrenocorticotropic secretion (EAS) is responsible for 12-17% of cases of Cushing's syndrome (CS) and covers a range of tumours, from undetectable benign lesions to widespread metastases. The syndrome is often associated with severe hypercortisolaemia, which aggravates the underlying condition. EAS requires a complete workup that includes the establishment of endogenous CS, diagnosis of...
متن کاملEctopic ACTH syndrome: clinicopathological correlations.
Ten out of 164 cases of bronchogenic carcinoma showed pathological evidence at necropsy of the ectopic ACTH syndrome. All occurred in association with oat-cell carcinoma, constituting 19% of that group. The pathological features consisted of adrenocortical hyperplasia confined to the zona fasciculata and Crooke's hyaline change in the pituitary. Immunoperoxidase stainable ACTH was detected in t...
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...
