Preeclampsia (PE) results of placental dysfunction and is one of the primary causes of maternal and fetal mortality and morbidity. During pregnancy, estrogen is produced primarily in the placenta by conversion of androgen precursors originating from maternal and fetal adrenal glands. These processes lead to increased plasma estrogen concentrations compared to non-pregnant women. Aberrant production of estrogens could play a key role in PE symptoms, since they are exclusively produced by the placenta and they promote angiogenesis and vasodilation...

Primitive neuroectodermal tumour (PNET) of kidney is a rare cancer typical of young adults with few cases described in the literature. We report a case of renal PNET in a 31-year-old man who presented to our department with a computed tomographic (CT)-scan revealing a large renal mass of 20 cm, massive thrombosis of the inferior vena cava (IVC). The patient underwent radical nephrectomy with contextual retroperitoneal lymphadenectomy and resection of IVC needing Dacron prosthesis substitution. Definitive histopathological examination showed PNET of kidney infiltrating ipsilateral adrenal gland, massive cava thrombosis with infiltration of vena cava wall and one lymph nodal metastasis...

CASE REPORT: A 71-year-old male with acute exacerbation of chronic bronchitis was treated in summer of 2015. The CT scan has revealed a mass on the right side of 11th thoracic vertebra in the adipose tissue with a sharp edge towards the lung and containing a small amount of contrast agent. The radiologist recommended histological sampling of the mass. The tumor was removed by Video-Assisted Thoracic Surgery (VATS) in August of 2015. The patient was discharged on the fifth postoperative day without complication...

Impaired β-cell function and insufficient β-cell mass compensation are twin pathogenic features that underlie type 2 diabetes (T2D). Current therapeutic strategies continue to evolve to improve treatment outcomes in different ethnic populations and include approaches to counter insulin resistance and improve β-cell function. Although the effects of insulin secretion on metabolic organs such as liver, skeletal muscle and adipose is directly relevant for improving glucose uptake and reduce hyperglycemia, the ability of pancreatic β-cells to crosstalk with multiple non-metabolic tissues is providing novel insights into potential opportunities for improving β-cell function and/or mass that could have beneficial effects in patients with diabetes...

The adrenal primary epithelioid angiosarcoma (ASE) is a rare malignant tumor which can be histologically confused with other neoplasms. We report one case in a 79-year-old man who underwent adrenal tumor surgery for a mass fortuitly discovered by imaging for examination of an inflammatory syndrome associated with anemia. The histological diagnosis was difficult because of the undifferentiated and epithelioid appearance of tumor cells, whose immunohistochemical epithelial markers positivity led to frequent confusion with a metastatic carcinoma...

Von Hippel-Lindau syndrome (VHLS) is an autosomal dominant hereditary familial disorder characterized by development of malignant and benign neoplasms. Differential diagnosis of the adrenal and pancreatic masses are difficult in patients with VHLS. Iodine-123 metaiodobenzylguanidine (I-123 MIBG) and indium-111 somatostatin receptor scintigraphies (In-111 SRS) have important roles in the differential diagnosis of adrenal and pancreatic masses in those patients. In this case report, we present the findings of I-123 MIBG single-photon emission computerized tomography (SPECT/CT) and In-111 SRS SPECT/CT in three members of a family with VHLS...

BACKGROUND AND AIMS: Scalp hair is increasingly used to measure the long-term exposure to endogenous glucocorticoids hormones. Long-term cortisone (HairE) and cortisol (HairF) have been associated with obesity, metabolic syndrome, cardiovascular disease and psychopathology. However, little is known about the influence of the use of local corticosteroids and major stressful life events on hair glucocorticoids. MATERIALS AND METHODS: We determined HairE and HairF using liquid chromatography - tandem mass spectrometry in 295 adult participants of the population-based Lifelines cohort study (75% females, median age 42)...

This 16-year-old boy presented with acute retrosternal pain possibly representing acute myocardial infarction. Cardiac enzymes were within reference ranges. There were marked increases in metanephrine to 3299 μg/24 h (reference, <400 μg/24 h), normetanephrine to 1309 μg/24 h (reference, 0-390 μg/24 h), and chromogranin A to 1605 ng/mL (reference, 0-150 μg/24 h). An incidental left adrenal mass was found during CTPA performed to exclude pulmonary embolism. I-MIBG scintigraphy was negative, and genetic screening detected SDHB (succinate dehydrogenase syndrome subunit B) gene mutation...

INTRODUCTION: Ectopic adrenal tissue is a very rare entity in adult females, especially in the ovary, and is generally diagnosed incidentally during surgery. Although it can present at various sites during childhood, it becomes atrophic by adulthood due to normally functioning adrenal glands. Patients are predominantly asymptomatic; however, in some cases endocrine symptoms such as hypertension and fasciotruncal obesity due to hormonal activity can be seen or neoplastic transformation can appear...

The adrenal-derived hormones dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are the most abundant circulating hormones and their levels decline substantially with age. DHEAS is considered an inactive precursor which is converted into androgens and estrogens via local metabolism in peripheral target tissues. The predictive value of serum DHEAS for fracture risk is unknown. The aim of this study was, therefore, to assess the associations between baseline DHEAS levels and incident fractures in a large cohort of older men...

Oncocytic neoplasms occur in several organs and are most commonly found in the thyroid, kidneys and salivary glands. Oncocytic neoplasms of the adrenal cortex are extremely rare and are usually non-functioning, benign and incidentally detected. However, histologically, they are characterized by cells with eosinophilic granular cytoplasm and numerous packed mitochondria. We report a case of 33 year old lady medically free complain of right flank pain radiated to the lower abdomen, not associated with any aggravating or relieving factor or any other symptom there was no evidence of hypertension symptom, by the Magnetic resonance imaging (MRI) showed that she has large heterogeneous mass seen at the right adrenal gland, and it was managed successfully by Robot-Assisted Right Adrenalectomy...

Schwannomas are typically slow growing, encapsulated benign neoplasms. Visceral schwannomas are rare, and preoperative diagnosis is challenging, as they are often confused with other neoplasms even with advanced imaging studies. Surgical excision is usually needed to establish a definitive diagnosis, as pathology is the "gold standard." We review the imaging findings of abdominal schwannomas focusing on pancreatic, gastrointestinal, and retroperitoneal/adrenal schwannomas with pathology correlation. We conclude that schwannoma should be included in the broad differential diagnosis of an abdominal mass and that when it is unnecessary radical resection can be avoided...

PET/CT was performed on an asymptomatic 62-year-old woman with a suspected adrenal mass and revealed the lesion with high F-FDG avidity and inferior vena cava involvement. A malignant nonfunctioning adrenal tumor was suspected. However, histopathology of the resected lesion revealed a leiomyoma arising from the inferior vena cava.

Huntingtin-associated protein 1 (HAP1) was initially identified as a binding partner of huntingtin, mutations in which underlie Huntington's disease. Subcellular localization and protein interaction data indicate that HAP1 may be important in vesicle trafficking, cell signalling and receptor internalization. In this study, a proteomics approach was used for the identification of novel HAP1-interacting partners to attempt to shed light on the physiological function of HAP1. Using affinity chromatography with HAP1-GST protein fragments bound to Sepharose columns, this study identified a number of trafficking-related proteins that bind to HAP1...

Carcinomas arising from embryonic adrenal rests are rare with only a handful of reported cases. We report a case of an adrenocortical carcinoma arising from an adrenal rest located between the bladder and prostate in a 51 year-old man. The patient presented following a year of rectal pain and constipation. Computed tomography (CT) scan revealed a 9 cm pelvic mass that appeared to arise from the soft tissue between the bladder and prostate, with displacement of the organs and narrowing of the rectal lumen, suspected to be a sarcoma...

The literature on adrenal gland tumour in HIV-infected patients is scarce. We report a 46-year-old Malay man with HIV and Hepatitis C infection presenting with a large nonfunctioning adrenal tumour. Computed tomography showed a large right adrenal tumour with heterogeneous enhancement and central necrosis. A high index of suspicion of a malignant tumour or pheochromocytoma led us to surgical removal of the adrenal gland. In this case report, we highlight important features to look for during pre-op evaluation of a large adrenal mass...

The primary functions of adrenal medullary chromaffin cells are the synthesis and storage in their chromaffin vesicles of the catecholamines noradrenaline (NA) and adrenaline (AD), and their subsequent release into the bloodstream by Ca(2+) -dependent exocytosis under conditions of fear or stress (fight or flight response). Several monoamines, nucleotides and opiates, such as leucine-enkephalin (LENK) and methionine-enkephalin (MENK), are also co-stored and co-released with the catecholamines. However, other neurotransmitters have not been studied in depth...
