Introduction: Primary Bilateral Macronodular Adrenal Hyperplasia (PBMAH) is a rare cause of ACTH-independent Cushing syndrome. It is characterized by the development of supracentimetric nodules resulting in increased adrenal volume and weight. Its presentation is clinically, radiologically and biologically heterogeneous. Morphological descriptions of PBMAH are rare. Although the initial description highlights that multinodular hyperplastic adrenal glands are made of a majority...

Introduction: Bilateral macronodular adrenal disease (BMAD) is a genetically heterogeneous disease that can be caused by ARMC5 or KDM1A alterations. Indeed, a germline and somatic event leading to a bi-allelic inactivation of ARMC5 or KDM1A are responsible for 20 and 1% of BMAD cases, respectively. Genetic analysis identified three molecular groups: ARMC5, KDM1A and no genetic cause known to date. Although there is a high h...

IntroductionPrimary bilateral macronodular adrenal hyperplasia (PBMAH), the most common cause of adrenal CushingÂ’s syndrome due to bilateral adrenal tumors, is an heterogenous disease with various clinical, hormonal and morphological characteristics. ARMC5 inactivating mutations is the most frequent genetic cause of PBMAH and variants of PDE11A4 have been associated with the disease. In order to better understand the heterogeneity ...

Introduction: In Primary Bilateral Macronodular Adrenal Hyperplasia (PBMAH), cortisol secretion may be consecutive to physiological stimuli, through the illegitimate expression of G-protein coupled receptors (GPCR) in adrenocortical cells. The most characterized is the overexpression of GIP receptor (GIPR) leading to food-dependent Cushing syndrome (FDCS) but it has not been associated with the consecutive inactivation of ARMC5 responsible for 25% of PBMAH. This work aimed to ...
