The majority of adrenocortical tumors (ACT) are benign and hormonally non-functioning, in contrast to adrenocortical carcinomas (ACC), which are rare and usually very aggressive tumors. The differential diagnosis between these two entities is mainly based on unspecific and subjective criteria, contributing to the inaccuracy of diagnosis. Due to ACC molecular and biological heterogeneity, prognostic factors have a limited capacity to predict ACC clinical outcomes, leading to an...

Arterial hypertension usually results from the deregulation and hyperactivity of the renin angiotensin-aldosterone system. One of the available therapeutic approaches for its treatment is the use of mineralocorticoid receptor (MR) antagonists, thus blocking aldosterone action.The aim of this study was to characterize the effects of spironolactone and eplerenone, on the morphology of the adrenal gland of spontaneously hypertensive (SHR) and normotensive (...

Introduction: The majority of adrenocortical carcinomas (ACC) autonomously produce steroids. However, urinary steroid profile of patients with ACC revealed that these tumors secrete and release predominantly intermediate metabolites. This steroid secretion pattern could be attributed to the undifferentiated status of the tumor cells expressing an incomplete pattern of enzymes involved in the steroidogenic cascade.Aims: Our study aim was to analyze the ex...

Adrenocortical carcinomas (ACC) are rare and usually very aggressive tumors with heterogeneous outcomes. The individual variability in tumor progression and patients’ survival is linked to ACC biology and molecular heterogeneity, reinforcing the need to identify markers with prognosis value, to allow an accurate clinical strategy. Currently, in the absence of specific molecular markers, ACC prognosis is mainly predicted by the European Network for the Study of Adrenal Tum...

Most of adrenocortical tumors (ACT) are benign and non-functioning tumors, in contrast to adrenocortical carcinomas (ACC), which are rare and usually very aggressive tumors with a poor prognosis. The pathological discrimination between adrenocortical adenomas (ACA) and ACC is mainly based on unspecific and subjective histological features, resulting in inaccurate diagnosis in several cases. Numerous studies have previously described the potential value of immunohistochemistry ...

BackgroundCurrently, serious complications of secondary hyperparathyroidism (sHPT) are rare due to early diagnosis and more effective treatments. These complications include osteitis fibrosa cystica, which is characterized by bone resorption and brown tumors. Depending on the location, they can cause pain or compressive symptoms.Case reportWe report a case of a 41-year-old black woman with a past medical hist...
