An unusual case of Cushing's syndrome: the importance of a stepwise approach to diagnosis.
This lesson describes a case of Cushing's syndrome secondary to ectopic adrenocorticotropin hormone (ACTH) secretion (EAS) by a thymic carcinoid tumour. This highlights the clinical features of EAS, its diagnosis and the importance of a methodical and logical approach to investigating this complicated condition.
