Molecular characterization of archival adrenal tumor tissue from patients with ACTHindependent Cushing syndrome.

Cushing syndrome represents a multitude of signs and symptoms associated with long-term and excessive exposure to glucocorticoids. Solitary cortisol-producing adenomas (CPAs) account for most cases of ACTH-independent Cushing syndrome (CS). Technological advances in next-generation sequencing have significantly increased our understanding about the genetic landscape of CPAs.

Molecular and Clinical Features of Adrenocortical Tumors in Beckwith-Wiedemann Spectrum.

Background/objectives: Adrenocortical tumors (ACTs), including adrenocortical adenoma (ACA) and carcinoma (ACC), represent 0.3-0.4% of pediatric tumors.

Cardiovascular risk improvement after laparoscopic adrenalectomy in patients with cortisol-secreting adrenal adenoma, a retrospective cohort study.

Background: Cushing syndrome increases morbidity and mortality, which is mainly caused by cardiovascular disorders. This study reports the cardiovascular risk outcomes at 3, 6, and 12 months after unilateral laparoscopic adrenalectomy in cortisol-secreting adrenal tumor and to identify the preoperative parameters predicting the resolution of cardiovascular risk factors after surgery.

Methods: All clinical data of patients with unilateral cortisol-secreting adrenal tumors who underwent laparoscopic adrenalectomy in King Chulalongkorn Memorial Hospital between 2001-2022 were retrospectively reviewed.

Benefits of transitioning from transperitoneal laparoscopic to retroperitoneoscopic adrenalectomy-a single center experience.

Background: Since 2017, switching from laparoscopic transabdominal adrenalectomy (LTA), posterior retroperitoneoscopic adrenalectomy (RPA) is used as standard procedure in this institution. Aim of this retrospective study was to compare both techniques regarding operative time, length of stay and safety of the procedures.

Methods: All patients operated in our institution for adrenal tumors were prospectively documented in the EUROCRINE-database and retrospectively analyzed.

Glucocorticoid replacement therapy after retroperitoneal laparoscopic unilateral adrenal adenoma resection in patients with non-cortisol secreting tumors: a retrospective cohort study.

Background: Adrenal Cushing's syndrome is caused by an adrenal tumor that produces hypercortisolism and requires glucocorticoid supplementation following resection of the tumour to prevent adrenal insufficiency. Few studies have examined whether glucocorticoid replacement (GR) therapy is required after retroperitoneal laparoscopic unilateral adrenal adenoma resection in patients with non-cortisol secreting tumors, or whether there is any correlation between preoperative biochemical indicators and postoperative cortisol function. This study sought to investigate which patients with non-cortisol secreting tumors required GR therapy after undergoing retroperitoneal laparoscopic resection of unilateral adrenal cortical adenoma.

Impact of Female Sex and Mild Cortisol Secretion on Coagulation Profile in Adrenal Incidentalomas.

Context: Studies describing the coagulation profile in adrenal adenomas still need to be added.

Objective: We explored how sex and mild autonomous cortisol secretion (MACS) affect coagulation parameters in patients with adrenal adenomas.

Design: Cross-sectional study.

[F]AlF-NOTA-pentixather PET/CT of CXCR4 in patients with suspected primary hyperaldosteronism.

Distinguishing unilateral aldosterone-producing adenomas (APA) from idiopathic hyperaldosteronism (IHA), nonfunctional adrenal adenoma (NFA), and pheochromocytoma (PHEO) within primary aldosteronism (PA) presents a significant challenge. Studies have demonstrated high levels of chemokine receptor (CXCR) 4 expression in APA, thereby validating the use of Ga-labeled CXCR4 PET/CT for detecting APA. This study evaluates the efficacy of [F]AlF-NOTA-pentixather PET/CT in distinguishing APA from other PA types.

Adrenal adenoma secreting 17-hydroxyprogesterone mimicking non-classical 21-hydroxylase deficiency.

In adrenal steroidogenesis, 17-hydroxyprogesterone (17-OHP) is a substrate for 21-hydroxylase, one of the crucial enzymes of the cortisol and aldosterone biosynthesis pathway. Thus, measurement serum 17-OHP concentration is used when the diagnosis of congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is suspected. In the classic 21-hydroxylase deficiency, randomly timed measurements of 17-OHP are generally significantly elevated using different immunoassays.

Co-Existing Ectopic Cortisol-Producing Adenoma and Retroperitoneal Schwannoma, a Rare Case Report.

Background: Ectopic cortisol-producing adrenocortical adenoma (ECPA) is extremely rare, with only a few cases reported. Retroperitoneal schwannoma is also uncommon, accounting for only 0.7-5% of all schwannomas.

Evaluation of Cardiometabolic Risk in Patients with Non-Functioning Adrenal Adenomas Using the Systematic Coronary Risk Evaluation 2 (SCORE2) and the Systematic Coronary Risk Evaluation 2-Older Persons (SCORE2-OP) Algorithms.

BACKGROUND Non-functioning adrenal adenomas (NFA) are prevalent tumors often associated with metabolic disturbances compared to the general population. This study aimed to evaluate cardiovascular disease (CVD) risk in 106 patients with NFA using SCORE2 and SCORE2-OP algorithms. MATERIAL AND METHODS The study sample comprised of 106 patients with NFA.

Clinical and Metabolic Characteristics and Follow-Up Results of Adrenal Incidentalomas: A 10-Year Experience.

Objective: In this retrospective study, we aimed to investigate the clinical, hormonal, and radiological characteristics of patients with adrenal incidentalomas (AIs), to assess the prevalence of metabolic syndrome components in patients with AIs, and to determine whether changes in tumor size or hormonal activity occur during long-term follow-up in patients with AIs.

Methods:  We retrospectively analyzed data from 384 patients diagnosed with AI between 2010 and 2020. Data regarding radiological, hormonal, and metabolic investigations in diagnosis and also during follow-ups were collected.

Contrast Enhanced CISS/FIESTA Imaging for Increased Conspicuity of Pituitary Microadenomas in Cushing Disease.

Background And Purpose: Pituitary microadenomas can be challenging to see on MRI, particularly when they are small. The detection of microadenomas commonly relies on contrast-enhanced sequences, highlighting the adenoma that demonstrates hypoenhancement relative to the native pituitary on T1-weighted sequences. Detecting adenomas in patients with Cushing disease is crucial, as surgery is the standard of care treatment.

Aldosterone-producing Multiple Micronodules With Several Different Pathogenic Variants.

Primary aldosteronism (PA) is the most common form of secondary hypertension. Recently, the genetic analysis of aldosterone-producing adenoma, a major cause of PA, has revealed several causative genes. Herein, we present a case of a 27-year-old Japanese female with PA.

Endogenous Cushing's Syndrome Due to Right Adrenal Adenoma Presenting With Bilateral Leg Oedema and Skin Ulceration.

Cushing's syndrome (CS) is a rare disorder characterized by an excess of glucocorticoids, leading to distinctive clinical manifestations. However, its presentation can be atypical, complicating diagnosis. We describe a 53-year-old woman's case of endogenous, adrenocorticotropic hormone (ACTH)-independent CS, presenting with bilateral leg edema and shin ulceration, without the classic signs of moon face or truncal obesity initially.

A Case of Cushing's Disease and a RET Pathogenic Variant: Exploring Possible Rare Associations.

Cushing disease (CD), a rare endocrine disorder characterized by a pituitary adenoma that secretes excess adrenocorticotropic hormone (ACTH), leads to overproduction of cortisol by the adrenal glands and, depending on severity and duration, manifests with a broad spectrum of clinical signs and symptoms, ranging from classical features to more common conditions seen in the general population. Discovery of molecular and pathogenic mechanisms related to the development of CD tumors has increased in recent years, almost two-thirds of the somatic variants cases have been linked to the USP8 gene, while very rare germline variants in MEN1 and AIP genes have been associated with pituitary adenomas. Variants affecting the RET proto-oncogene, which encodes a receptor tyrosine kinase involved in cell growth and differentiation, are implicated in the development of medullary thyroid carcinoma (MTC) and its hereditary form, multiple endocrine neoplasia type 2 (MEN2).
