A 47-year-old Caucasian man was referred to our clinic with a severe clinical and biochemical phenotype of endogenous hypercortisolism for further evaluation and treatment. In addition to confirming adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome, we found left temporal hemianopsia, massively increased prolactin, increased growth hormone/insulin-like growth factor 1 values, hypogonadotropic hypogonadism and central hypothyroidism. As the cause of these abnormalities we revealed an invasive macroadenoma of the pituitary secreting ACTH, prolactin and growth hormone, resulting not only in a clinically predominant picture of Cushing’s syndrome but also causing hypogonadotropic hypogonadism and central hypothyroidism. The patient responded surprisingly well to dopamine agonist treatment leading not only to normalisation of prolactin levels but also to clinical and biochemical remission of Cushing’s syndrome. Tumour size decreased successively in follow-up MRI scans. Despite lacking immunohistochemical analysis of tumour tissue, we assume plurihormonal secretion of ACTH, prolactin and growth hormone from pituitary macroadenoma, which fortunately responded well to dopamine agonist treatment.

Abstract Cushing's syndrome in childhood is generally recognized by classical features such as truncal obesity, striae, easy bruising, moon facies, hypertension and growth retardation. Exceptionally, Cushing's syndrome has been reported to present as growth failure alone. We diagnosed transient hypercortisolism in 6 children who had poor growth as their only presenting abnormality. The 6 children all had integrated concentrations of cortisols (IC-F) (14.1+1.7 μg/dl; mean±ISD) which exceeded the IC-F in healthy children and adults (5.7±1.5 μg/dl; P<0.001). The IC-F of these 6 index cases overlapped the range of IC-F in patients with pathologically proven Cushing's syndrome (20.2±4.7 μg/dl). Four of the 6 patients were treated with human growth hormone for 8 months and showed a marked improvement in their growth rates. Four patients have entered puberty and are growing at normal rates. Three of the 6 children had normal repeat IC-Fs, subsequently, at a time they had normal growth rates. In 1-1/2 to 3 years of follow-up, none of the patients developed any other stigmata of Cushing's syndrome. We conclude that transient hypercortisolism, documented by the IC-F, may cause growth failure without other symptoms of Cushing's syndrome. Growth hormone therapy may improve the growth rate of these children at the time of their poor growth.

Ectopic Adrenocorticotropic Hormone

Abstract Background Ectopic adrenocorticotropic hormone secretion syndrome occurs in 10% of all patients with adrenocorticotropic-hormone-dependent hypercortisolism. It is usually associated with overt malignancies or with occult and indolent tumors. This study aims to confirm the source of ectopic adrenocorticotropic hormone in four patients with ectopic Cushing’s syndrome over time. Case presentation A 38-year-old Iranian man with Cushing’s syndrome underwent bilateral adrenalectomy since the source of ectopic adrenocorticotropic hormone secretion was not localized and pituitary imaging was normal. A whole-body scan revealed a right-lung tumoral mass with mediastinal lymph node metastasis. The mass was assumed a lung carcinoid tumor with mediastinal adenopathy. Right-lung mid-zone lobectomy and mediastinal lymphadenectomy were done. In a 47-year-old Iranian man with Cushing’s syndrome, whole-body computed tomography scan revealed a pulmonary nodule in the posterior segment of the left lower lobe of the lung. The third case was a 25-year-old Iranian man who presented with symptoms and signs of Cushing’s syndrome. Pituitary magnetic resonance imaging revealed a microadenoma 5 × 9 mm. Whole-body scan showed abnormal focal somatostatin receptors analog avid lesion in the posterior aspect of inferior third of right lung, highly suggestive of ectopic adrenocorticotropic-hormone-producing tumor. The last case was a 43-year-old Iranian woman with Marfan syndrome with a history of mitral and aortic valve replacement and chronic dissection of the aorta, who presented with symptoms and signs of Cushing’s syndrome. She underwent bilateral adrenalectomy 1 year later owing to failure to locate ectopic adrenocorticotropic hormone syndrome. Whole-body scan showed abnormally increased radiotracer uptake in the midline of the skull base and posterior aspect of the middle zone of left hemithorax and bed of left lobe of thyroid. Conclusion The clinical spectrum of ectopic adrenocorticotropic hormone secretion syndrome is wide, and distinguishing Cushing’s disease from ectopic adrenocorticotropic hormone secretion syndrome is difficult. Initial failure to identify a tumor is common. Pulmonary carcinoid or occult source of ectopic adrenocorticotropic hormone secretion syndrome is usually the cause. In occult cases of ectopic adrenocorticotropic hormone in which the tumor cannot be localized, serial follow-up with serial computed tomography, magnetic resonance imaging, or scintigraphy is recommended for several years until the tumor can be localized and treated.

ObjectiveTo evaluate long-term morphological, functional, and clinical outcome in adrenal incidentalomas.Design and methodsA total of 118 patients (77 F and 47 M; age 62.3±1.0 years) with adrenal incidentalomas were evaluated at baseline and followed-up for median 3 years (range 1–10 years) by clinical, biochemical, hormonal, and morphological evaluation. Among them, six patients with diagnosis of subclinical Cushing's syndrome (SCS) underwent surgery.ResultsAt entry, 86% (n=102) of tumors were nonfunctioning (NF) and 14% (n=16) showed SCS. Comparing NF with SCS patients, a significantly higher percentage of dyslipidemia was found in the group of SCS patients (50 vs 23%,P=0.033). During follow-up, adrenal function remained normal in all NF patients, none of them developed subclinical or overt endocrine disease. The cumulative risk of mass enlargement was globally low (25%), but progressive up to 8 years. SCS was confirmed in all patients, and none of them shifted to overt Cushing's syndrome. The cumulative risk of developing metabolic–cardiovascular abnormalities was globally low (22%), but progressive up to 8 years and new diseases were recorded in the group of NF patients only (three patients with dyslipidemia, four with impaired fasting glucose/impaired glucose tolerance, and three with diabetes mellitus). SCS patients who underwent surgery did not show any significant clinical improvement.ConclusionsThe risk of mass enlargement, hormonal, and metabolic impairment over time is globally low. Conservative management seems to be appropriate, but further prospective studies are needed to establish the long-term outcome of such patients, especially for metabolic status, cardiovascular risk profile and their relationship with endocrine function.

Thymic hyperplasia has been described after the resolution of hypercortisolism from several etiologies, causing great diagnostic dilemmas. We describe a case where the catheterization of the thymic vein was essential for the differential diagnosis of a thymic enlargement in an adrenalectomized patient with ACTH-dependent Cushing’s syndrome. The patient was a 48-year-old female with clinical and laboratorial data suggesting Cushing’s disease. She underwent a transsphenoidal surgery with no tumor visualization and no remission of the syndrome. Histopathological studies disclosed a normal pituitary. She underwent a bilateral adrenalectomy and 8 months later a chest CT showed an increase of left thymic lobe, which was previously non-existent. After a negative 111In-pentetreotide scintigraphy, the patient underwent simultaneous and bilateral catheterism of the petrosus sinuses and catheterization of the thymic and inominate veins and no ACTH gradient was shown among the sites of collection. She did not undergo thoracotomy and a follow-up was established. During the evolution, there was a spontaneous regression of the thymic lesion 38 months after the diagnosis. The ACTH gradient during the catheterization of thymic vein was essential for the differential diagnosis of the thymic enlargement tumor after hypercortisolism resolution in ACTH-dependent Cushing’s syndrome, especially in this case, where the ACTH source was occult, thus avoiding an invasive surgical procedure for a benign entity with spontaneous resolution.

Primary Presentation

Cushing’s syndrome is known to present with a characteristic set of clinical manifestations and complications, well described in literature. However, hypercoagulability remains an under recognised entity in Cushing’s syndrome. A 31-year-old woman from Southern India presented with history of fever, left upper quadrant pain and progressive breathing difficulty for 3 weeks. Clinical examination revealed discriminatory features of Cushing’s syndrome. Laboratory investigations showed biochemical features of endogenous ACTH-dependent Cushing’s syndrome. Imaging of the abdomen revealed splenic collection, left-sided empyema and extensive arterial thrombosis. Gadolinium enhanced dynamic MRI of the pituitary gland revealed no evidence of an adenoma while a Ga-68 DOTATATE positron emission tomography CT scan ruled out an ectopic Cushing’s. A diagnosis of endogenous Cushing’s syndrome causing a prothrombotic state with extensive arterial thrombosis was made. She was initiated on oral anticoagulation and oral ketoconazole for medical adrenal suppression. She subsequently underwent bilateral adrenalectomy and was well at follow-up.

Abstract Background We do not fully understand how hypercortisolism causes central hypothyroidism or what factors influence recovery of the hypothalamic-pituitary-thyroid axis. We evaluated thyroid function during and after cure of Cushing’s syndrome (CS). Methods We performed a retrospective cohort study of adult patients with CS seen from 2005 – 2018 (cohort 1, c1, n=68) or 1985 – 1994 (cohort 2, c2, n=55) at a clinical research center. Urine (UFC) and diurnal serum cortisol (F: ~8AM and ~midnight (PM)), morning triiodothyronine (T3), free thyroxine (FT4) and thyroid stimulating hormone (TSH) (c1) or hourly TSH from 1500-1900h (day) and 2400-04000h (night) (c2), were measured before and after curative surgery. Results While hypercortisolemic, 53% of c1 had central hypothyroidism (low/low normal fT4 + unelevated TSH). Of those followed long-term, 31% and 44% had initially subnormal FT4 and T3, respectively, which normalized 6—12 months after cure. Hypogonadism was more frequent in hypothyroid (69%) compared to euthyroid (13%) patients. Duration of symptoms, AM and PM F, ACTH, and UFC were inversely related to TSH, FT4 and/or T3 levels (r -0.24 to -0.52, P &lt;0.0001 to 0.02). In c2, the nocturnal surge of TSH (mIU/L) was subnormal before (day 1.00±0.04 vs night 1.08±0.05, p=0.3) and normal at a mean of 8 months after cure (day 1.30±0.14 vs night 2.17±0.27, p=0.01). UFC &gt;1000 μg /day was an independent adverse prognostic marker of time to thyroid hormone recovery. Conclusions Abnormal thyroid function, likely mediated by subnormal nocturnal TSH, is prevalent in Cushing’s syndrome and is reversible after cure.

ContextEctopic ACTH syndrome (EAS) is principally associated with aggressive malignant tumors but also with neuroendocrine tumors of good prognosis. Recently, rare nonhepatocytic nested stromal and epithelial tumors (NSET) were characterized by their possible association with Cushing's syndrome of which biochemical and physiopathological features were still incompletely studied.ObjectiveTo describe the clinical and hormonal characteristics of an EAS originating from a liver NSET and further understand the mechanism of cortisol overproduction.Design and settingThis is a clinical case report from the Endocrinology Department of Caen University Hospital, France.Patient and interventionA 17-year-old female patient was found to have a large liver NSET with mild Cushingoid clinical features and intense biological hypercortisolism but moderate ACTH secretion. Resection of the tumor was curative with a 30-month follow-up.ResultsThe epithelial component of the tumor coexpressed ACTH mildly, corticotropin-releasing hormone (CRH) strongly, and 11β-hydroxysteroid dehydrogenase at a level comparable with normal human hepatocytes.ConclusionsLiver NSET is a new cause of EAS, which may evoke hypercortisolism by multiple biochemical pathways.
