Ectopic adrenocorticotrophic hormone syndrome. A case report

Excessive production of adrenocorticotrophic hormone (ACTH) by oat cell carcinomas and carcinoid tumours of the lung has been well documented. Florid cases of Cushing's syndrome secondary to the excessive production of ACTH by the tumour are rare. In this article 2 cases of florid Cushing's syndrome associated with oat cell carcinoma are described.
