INTRODUCTION: Ectopic Cushing's syndrome (ECS) is a rare condition caused by ACTH secretion by extrapituitary tumors. Its low frequency makes it difficult to acquire experience in its management. The aim of this study was to describe patients with ECS seen at the endocrinology department of a tertiary hospital over 15 years. METHODS: This was a retrospective study of the clinical, biochemical and radiographic data, treatment, and course of patients with ECS seen from 2000 to 2015...

Pancreatic neuroendocrine tumors (pNETs) constitute a heterogenous group of malignancies with varying clinical presentation, tumor biology and prognosis. The incidence of pNETs has steadily increased during the last decades with an estimated incidence 2012 of 4.8/100,000. Recent whole genome sequencing of pNETs has demonstrated mutations in the DNA repair genes MUTYH and point mutations and gene fusions in four main pathways from chromatin remodeling, DNA damage repair, activation of mechanistic target of rapamycin (mTOR) signaling and the telomere maintenance...

BACKGROUND: Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is caused by tumours releasing ACTH. Ectopic ACTH-producing tumour regression is rarely induced using steroidogenesis inhibitors. We presented a case of EAS in which ACTH production by a lung tumour was reduced by metyrapone (MTP) and also reviewed previous cases of ectopic ACTH production suppressed via steroidogenesis inhibition. CASE PRESENTATION: A 71-year-old female with general fatigue, central obesity and impaired glucose tolerance was diagnosed with Cushing's syndrome due to elevated ACTH (192...

The objective of this study is to report three cases of paraneoplastic or ectopic Cushing syndrome, which is a rare phenomenon of the adrenocorticotropic hormone (ACTH)-dependent Cushing syndrome. Three cases are reported in respect of clinical presentation, diagnosis and treatment in addition to relevant literature review. The results showed that ectopic ACTH secretion can be associated with different types of neoplasm most common of which are bronchial carcinoid tumors, which are slow-growing, well-differentiated neoplasms with a favorable prognosis and small-cell lung cancer, which are poorly differentiated tumors with a poor outcome...

A 62-year-old woman presented with an 11-month history of worsening nasal symptoms of rhinorrhoea, anosmia, nasal congestion and intermittent epistaxis. MRI revealed a large mass in the upper nasal vault. Biopsy of the mass revealed an olfactory neuroblastoma. While waiting resection, she acutely developed severe proximal muscle weakness, lethargy and lower extremity oedema. Blood glucose was elevated, and hypokalaemic metabolic alkalosis was noted. Elevated serum cortisol level of 95.7 µg/dL (8.7-22.4 µg/dL) and markedly elevated 24-hour urinary cortisol level of 6962...

Ectopic adrenal adenoma causing chronic Cushing's syndrome (CS) is a rare phenomenon. Diagnosis is usually made years after disease onset because of the insidious nature of the ectopic adrenal gland and because it overlaps with common symptoms, such as overweight and hypertension, in the general population (Kreitschmann-Andermahr et al., 2015). Here, we report the case of a 46-year-old male with a 15-year history of severe hypertension, facial plethora, and centripetal obesity. During treatment for herpes zoster, the patient presented with severe hypokalemia and flaccid paralysis, characteristic changes associated with CS...

We present a case of a 52-year-old male who developed Cushing's Syndrome due to ectopic adrenocorticotrophic hormone (ACTH) secretion from a large esthesioneuroblastoma (ENB) of the nasal sinuses. The patient initially presented with polyuria, polydipsia, weakness, and confusion. Computed tomography scan of the head and magnetic resonance imaging showed a 7 cm skull base mass centered in the right cribriform plate without sella involvement. Work-up revealed ACTH-dependent hypercortisolemia, which did not suppress appropriately after high-dose dexamethasone...

Desmopressin is a vasopressin analogue selective for type 2 vasopressin receptors that mediate renal water retention. In contrast to the native hormone arginine-vasopressin, a well-known ACTH secretagogue, desmopressin exerts minimal or no activity on ACTH excretion. However, in a substantial proportion of patients with ACTH-dependent Cushing's syndrome (CS), desmopressin elicits an ACTH and cortisol response, which contrasts with the minimal responses obtained in healthy subjects. The mechanism underlying this paradoxical response involves upregulation of vasopressin type 3 and/or the aberrant expression of type 2 receptors by neoplastic ACTH-producing cells...

CONTEXT: Bilateral inferior petrosal sinus sampling (BIPSS) using hCRH is currently considered the 'gold standard' test for the differential diagnosis of ACTH-dependent Cushing's syndrome (CS). Vasopressin is more potent than CRH to stimulate ACTH secretion as shown in animal studies, however; no comparative data of its use is available during BIPSS. OBJECTIVE: To study the diagnostic accuracy and comparison of hCRH and lysine vasopressin (LVP) stimulation during BIPSS...

Endocrine paraneoplastic syndromes result from the production of bioactive substances from neoplastic cells, of endocrine or neuroendocrine origin. Typically these are located in the lungs, the gastrointestinal tract, pancreas, thyroid gland, adrenal medulla, skin, prostate or breast. In endocrine paraneoplastic syndromes the secretion of peptides, amines or other bioactive substances is always ectopic and not related to the anatomical source. The clinical presentation, however, is indistinguishable from a suspected eutopic endocrine tumor posing a diagnostic challenge...

We present the case of a patient with Cushing's syndrome secondary to ectopic ACTH secretion. A MR of the head showed a left-sided nasal mass extending down from the cribriform plate. The patient underwent endoscopic resection with nearly complete removal of the mass. Histological examination showed an ACTH-secreting olfactory neuroblastoma (ONB). The patient's cortisol levels returned to normal range after surgery and have remained normal for over a year. ONB is a rare cause for ectopic ACTH secretion. This case highlights the diagnostic and management difficulties in patients with ectopic ACTH secretion, and provides a brief review of ONB...

BACKGROUND: With the increasing access to imaging more pheochromocytomas are diagnosed in the workup of adrenal incidentalomas. This may have changed the occurrence of the classic presentation with hypertension and the classic triad (headaches, sweating and palpitation). METHODS: We reviewed 94 consecutive cases of pheochromocytomas. Two cases of ectopic ACTH-syndrome were subsequently excluded. RESULTS: Of the 92 cases included 64% had presented as an incidentaloma, 32% as a suspected pheochromocytoma and 4% had been screened because of previously diagnosed MEN2A...

INTRODUCTION: Ectopic Cushing syndrome is a form of Cushing's in which a tumor outside the pituitary gland produces adrenocorticotropic hormone (ACTH). Small cell carcinoma and carcinoid of the lung comprises half of its cases. The main purpose of this study is to present a case of ectopic Cushing syndrome caused by a hidden lung carcinoid and how to manage it. PRESENTATION OF CASE: Here we present a case of a 26year old young male complains of increased weight and appetite, proximal muscle weakness, easy bruising and appearing of purple striae on his abdomen, with a final diagnosis of ACTH secreting lung carcinoid...

The criterion standard of treatment of an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma is complete surgical excision. However, ectopic location of these adenomas is an extremely rare condition, which may affect the diagnosis and treatment success. We report a case of a 49-year-old man who was referred to our institution with persistent hypercortisolemia after an unsuccessful attempt of surgical resection. F-choline PET/CT revealed increased radiopharmaceutical uptake in a nodule localized in the left maxillary sinus, which was proved at histology to be an ectopic ACTH-secreting pituitary adenoma staining positive for ACTH...

In 2013 more than 150,000 Americans died from all types of lung cancer. Small cell lung cancer (SCLC) represents about 13% of all lung cancers and is notoriously associated with paraneoplastic syndromes (PNS). Here we present an interesting case of psychosis associated with one such PNS-- ectopic Cushing syndrome of SCLC. A 56 year old African-American male with no prior psychiatric history who was diagnosed with SCLC two months prior, presented to the ER for treatment of a right arm laceration he sustained while fighting off attackers, with high concern these individuals may have been part of hallucinatory experiences and well-systematized persecutory delusions regarding his wife...

Context: Cushing syndrome is rarely caused by the secretion of cortisol from ovarian tumors. In clinical decision-making, it is important to determine whether the ovarian tumor is capable of secreting cortisol. Selective ovarian and adrenal venous sampling is scarcely reported in the localization of ACTH-independent ectopic Cushing syndrome. Case Description: We present a case of 40-year-old Chinese woman who had weight gain, hirsutism, hypertension, and menstrual disorder over 6 months...

Cushing's syndrome is a rare disease that results from prolonged exposure to supraphysiological levels of glucocorticoids. Severe and rapidly progressive cases are often, but not exclusively, attributable to ectopic ACTH secretion. Extreme hypercortisolism usually has florid metabolic consequences and is associated with an increased infectious and thrombotic risk. The authors report on a case of a 51-year-old male that presented with severe Cushing's syndrome secondary to an ACTH-secreting pituitary macroadenoma, whose diagnostic workup was affected by concurrent subclinical multifocal pulmonary infectious nodules...

A 60-year-old man with a pre-existing stable sacrococcygeal teratoma developed acromegaly, ectopic Cushing's syndrome, and 5HIAA secretion. To our knowledge, this represents the first reported case of ACTH and serotonin secretion, and likely GHRH or GH cosecretion, from a sacrococcygeal teratoma in an adult.

Ectopic adrenocorticotropic hormone (ACTH)-related Cushing's syndrome can lead to multiple complications including severe immunosuppression. If the ACTH-secreting tumour cannot be found, definitive treatment is surgical adrenalectomy, typically followed by glucocorticoid replacement. Here, we present a case of fulminant respiratory failure secondary to coinfection with Pneumocystis jirovecii and cytomegalovirus in a patient with ectopic ACTH-dependent Cushing's syndrome with occult primary. Due to significant deconditioning, she was unable to undergo definitive adrenalectomy and instead underwent percutaneous microwave ablation of the adrenal glands...

Growth hormone deficiency (GHD) can present at any time of life from the neonatal period to adulthood, as a result of congenital or acquired insults. It can present as an isolated problem (IGHD) or in combination with other pituitary hormone deficiencies (CPHD). Pituitary deficits can evolve at any time from GHD diagnosis. The number, severity and timing of occurrence of additional endocrinopathies are highly variable. The risk of progression from IGHD to CPHD in children varies depending on the etiology (idiopathic vs organic)...
