Two Cases of Ectopic ACTH-Secreting Neoplasm of Occult Origin Becoming Overt After Bilateral Adrenalectomy
Introduction: Cushing's syndrome (CS) is an endocrine disorder associated with serious consequences if not adequately treated. Nearly 80% of the cases of endogenous hypercortisolism are adrenocorticotropic hormone (ACTH) dependent, the ACTH source being pituitary in about 70-80% and ectopic in 10-15%. The ACTH source may remain occult in few cases for many years in spite of extensive investigations.
Materials and methods: we describe a retrospective series of 13 patients affected by ectopic ACTH dependent CS. The origin of ectopic ACTH secretion was: bronchial carcinoid for 8 patients, 1 atypical thymic carcinoid and in 4 cases the origin remained occult.
