Iatrogenic Cushing's syndrome (CS) is a severe adverse effect of systemic glucocorticoid (GC) therapy in children, but is extremely rare in the setting of topical ocular GC therapy. In this article, we report the case of a 9-year-old girl suffering from idiopathic uveitis who developed CS due to topical ocular GC treatment. She was referred to the ophthalmology department with a complaint of painful eyes, at which time she was diagnosed with bilateral iridocyclitis and started on a treatment of betamethasone sodium phosphate eye drops...

Small cell lung cancer (SCLC) is a neuroendocrine tumor with the potential to secrete various peptides or hormones that can lead to paraneoplastic syndromes, such as Ectopic Cushing syndrome (ECS). Because of the aggressive nature of the syndrome and its atypical features, ECS in small-cell lung cancer is difficult to diagnose and has a poor prognosis. We report a case of a 74-year-old male patient who presented with severe hypokalemia, proximal muscle weakness, peripheral edema, metabolic alkalosis, and worsening hyperglycemia...

Most frequent causes of androgenic manifestation are Cushing's syndrome, PCO, benign and malignant androgen-secreting non adrenal tumors and iatrogenic hirsutism. Hyperplasia or neoplasms of ectopic adrenocortical gland are rare. We report a case of a 63-year old female with hirsutism and alopecia. Laboratory data highlighted increased levels of androgens. Diagnostic imaging revealed normal morphology of adrenocortical gland and ovaries. In view of the clinical picture and suspected diagnosis of extra-adrenal cause, she underwent bilateral salpingo-oophorectomy...

Malignant tumors account for most sources of ectopic ACTH Cushing syndrome (EA-CS). Early localization of the source and complete removal can be curative and also prevent metastasis. Diagnostic CT is known to perform better than PET/CT (low dose) in characterizing lung pathologies. However, bronchial carcinoids, a common source of EA-CS, may be difficult to detect on chest CT scan especially when it is small and located close to the hilar region. We present a case of EA-CS due to bronchial carcinoid, which was easily seen on Ga DOTANOC PET/CT after a diagnostic chest CT was reported as normal...

Diagnosis of Cushing's syndrome (CS) and identification of the aetiology of hypercortisolism can be challenging. The Endocrine Society clinical practice guidelines recommends one of the four tests for initial screening of CS, namely, urinary-free cortisol, late night salivary cortisol, overnight dexamethasone suppression test or a longer low-dose dexamethasone suppression test, for 48 hours. Confirmation and localisation of CS requires additional biochemical and radiological tests. Radiological evaluation involves different imaging modalities including MRI with or without different radio-nuclear imaging techniques...

CONTEXT: Medullary thyroid carcinomas (MTCs) complicated by ectopic Cushing's syndrome have a poor prognosis, partially due to the difficulties to control hypercortisolism by adrenal blocking drugs. Recent reports (including the initial follow-up of this patient) have suggested that tyrosine kinase inhibitors (TKIs) may be a therapeutic option due to an antisecretory action on ACTH. However, there is a lack of long-term follow-up studies. CASE DESCRIPTION: We report the case of a 58 year-old man with a MTC-related Cushing's syndrome resistant to a combination of several anticortisolic drugs...

Cortisol is a steroid hormone produced in response to stress. It is essential for maintaining health and well-being; and leads to significant morbidity when deficient or present in excess. It is lipophillic and is transported bound to cortisol-binding globulin (CBG) and albumin; a small fraction (~10%) of total serum cortisol is unbound and biologically active. Serum cortisol assays measure total cortisol and their results can be misleading in patients with altered serum protein concentrations. Automated immunoassays are used to measure cortisol but lack specificity and show significant interassay differences...

Cushing's syndrome following topical ocular corticosteroid use is extremely rare. We describe a case of symptomatic Cushing's syndrome in an adolescent male with sight-threatening vernal keratoconjunctivitis on antiretroviral therapy for HIV-1 infection that included ritonavir, a potent cytochrome p450 CYP3A4 inhibitor. CYP3A4 inhibition reduces the metabolism of exogenous corticosteroids leading to suppression of endogenous steroid production and Cushing's syndrome.

Prolonged exposure to cortisol is one of the major causes of avascular bone necrosis (AVN). We report on a case of a woman with Cushing syndrome attributed to ectopic adrenocorticotropic hormone-secreting tumor who was evaluated with whole-body PET/CT study using Ga-DOTATATE. The scan showed increased activity by both femoral heads, corresponding to the margins of bilateral AVN seen on MRI. The presented data suggests AVN-induced reactive inflammatory alterations adjacent to the necrotic segment of the bone, which can be effectively targeted using radiolabeled somatostatin (SST) analogs...

BACKGROUND/PURPOSE: Cushing's disease (CD) is the most common cause of endogenous Cushing's syndrome. Transsphenoidal surgery (TSS) is the first choice of treatment. Predicting prognosis after treatment can benefit further strategies of management, but currently there is no convenient predictor. This study aims to investigate characteristic changes after treatment and to identify potential prognostic predictors. METHODS: We retrospectively studied the records of CD patients presenting to the National Taiwan University Hospital, Taipei, Taiwan between 1992 and 2011...

BACKGROUND: In subclinical Cushing syndrome (SC), it is assumed that glucocorticoid production is insufficient to cause a clinically recognizable syndrome. Differences in hormonal levels or recovery time of the hypothalamic-pituitary-adrenocortical (HPA) axis after adrenalectomy between patients with overt Cushing syndrome (OC) and SC remain unknown. METHODS: Thirty-six patients (10 with OC and 26 with SC) with adrenal Cushing syndrome who underwent adrenalectomy from 2004 to 2014 were reviewed retrospectively...

CONTEXT: Cortisol has been suggested as a risk factor for choroidal thickening, which may lead to retinal changes. OBJECTIVE: To compare choroidal thickness measurements using optical coherence tomography (OCT) in patients with endogenous active Cushing's syndrome (CS) and to evaluate the occurrence of retinal abnormalities in the same group of patients. DESIGN: Cross-sectional study. SETTING: Outpatient clinic. PATIENTS: Eleven female patients with CS in hypercortisolism state as determined by the presence of at least two abnormal measurements from urinary cortisol 24 h, no suppression of cortisol with low dose dexamethasone suppression test, and nocturnal salivary cortisol levels and 12 healthy controls...

BACKGROUND: Complete surgical resection of an adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma is the gold standard of treatment of Cushing disease. Ectopic location of these adenomas is an extremely rare condition that may compromise the diagnosis and surgical success. We present the first case of an ectopic intracavernous ACTH-secreting macroadenoma totally resected with endoscopic endonasal surgery (EES).

OBJECTIVE: Adrenal tumors are rare in children. The aim of this study is to review and analyze clinical data on the diagnosis and management of adrenal tumors in children. METHODS: Between 2001 and 2015, 48 pediatric patients (<14 years old) admitted to our institute with adrenal tumors were reviewed. Clinical features, imaging studies, surgical approaches, as well as pathological diagnoses were recorded. RESULTS: The series comprised 28 males and 20 females...

Part 2 of this 4-part continuing medical education series continues with a discussion of the prevention and management of gastrointestinal side effects associated with corticosteroid use, including peptic ulcer disease, gastrointestinal bleeding, and pancreatitis, followed by a review of corticosteroid-related endocrinologic side effects, such as diabetes, adrenal suppression, and Cushing syndrome.

The urinary free cortisol (UFC) test is widely used for the screening of Cushing's syndrome. This case study illustrates the potential failure of the UFC test to correctly diagnose Cushing's disease (CD), indicating that the use of other complementary tests may be necessary to diagnose this disease in some cases.

BACKGROUND: Differential diagnosis of hypokalemia and adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome often presents challenging in endocrinology and requires careful clinical, biochemical, radiological, and pathological investigations. Hypokalemia is a common abnormality and systematic approach is required to avoid delays in diagnosis of important underlying causes.
