Abstract

Cushing’s syndrome (CS) results from long-standing exposure to excessive circulating levels of glucocorticoids (Newell-Price et al., Lancet 367:1605–1617, 2006). Recently, the prevalence of both exogenous and endogenous CS has shown a marked rise because of the increased use of glucocorticoids in several degenerative diseases along with an early identification of subclinical forms of endogenous hypercortisolaemia. The early recognition and effective management of CS is of great importance as, when untreated, it is associated with high morbidity due to its metabolic abnormalities and the risk of infection resulting in increased mortality rates.

A florid clinical presentation makes diagnosis straightforward: when the clinical features are less obvious as in subclinical (SCS) or cyclic CS (CyCS), a step-by-step approach may confirm or reject the diagnosis, or dictate a longer close follow-up. Later on, a specific management targeting to the aetiology or the symptoms of CS may follow.

This chapter will first describe the aetiology of CS, review certain epidemiological data and clinical features, followed by a suggested diagnostic and therapeutic management paradigm.
