Introduction: Carney complex (CNC) is a rare multiple neoplasia syndrome characterized by pigmented lesions of the skin and mucosa in association with various endocrine and non-endocrine tumors. The disease can be inherited in an autosomal-dominant fashion or occur sporadically due to novel mutations in the PRKAR1A gene. Primary pigmented nodular adrenocortical disease (PPNAD) is a common endocrine manifestation of CNC.Case description: A 20-year-old wom...

The cell-cell interactions that occur within the breast tumor microenvironment are critical determinants of cancer cell fate. In the face of treatment, the theory of clonal evolution dominates current thinking. Thus, individual cells may acquire a mutation(s) that provides a selection advantage, i.e., Darwinian selection acts at the single cell level. We studied the effect of antiestrogen treatment on the population remodeling ...

Background: The overwhelming majority of incidentally discovered adrenal tumours are benign adrenocortical adenomas. These can be non-functioning (NFAT) or associated with cortisol excess on a spectrum ranging from rare clinically overt adrenal Cushing’s syndrome (CS) to much more prevalent mild autonomous cortisol secretion (MACS) without signs of CS. The 1mg-overnight dexamethasone suppression test (DST) further differentiates MACS-1 (possible MACS; post-DST cortisol 50...

Background: Benign adrenal tumours are found in 3-10% of adults and can be non-functioning (NFAT) or associated with adrenal hormone excess. Analysing 1305 prospectively recruited patients with benign adrenal tumours, we recently demonstrated that 45% had mild autonomous cortisol secretion (MACS), i.e. biochemical cortisol excess without signs of Cushing’s syndrome (CS). MACS increases the prevalence and severity of hypertension and type 2 diabetes (Ann Int Med. 2022 Doi:...
