CUSHING'S SYNDROME
Cushing’s syndrome is a condition which is due to prolonged exposure of the body tissue to excess cortisol (glucocorticoid hormone).
Laboratory tests and radiological findings confirm diagnosis and determine the actual cause of Cushing's syndrome.
Endogenous adrenocorticotropic hormone (ACTH)-independent Cushing's syndrome has adrenal hypersecretion due to adrenal adenoma, adrenal carcinoma, micronodular hyperplasia, and macronodular hyperplasia.
Exogenous ACTH-independent Cushing's syndrome has adrenal hypersecretion due to iatrogenic causes (eg drug-induced, corticosteroid use).

Differential Diagnosis

  • Identify cause & treat appropriately
  • Pseudo-Cushing’s syndrome
    • Due to non-endocrine disorders (eg major depressive disorder or chronic alcoholism)
    • Identify the cause & treat appropriately
    • Major causes: Major depressive disorder, chronic alcoholism

This case scenario was presented at a grand round in the Department of Medicine, The University of Hong Kong. Unlike traditional grand rounds that directly or indirectly deal with clinical challenges posed by patients, this one was equally about doctors and how they care for their charges. All doctors who tend patients dread being implicated on the receiving end of medico-legal proceedings. This topic is therefore intimately linked to the professionalism of doctors, their standing in the community, and the ethical aspects of how they interact with patients and relatives.
