Carcinoid tumour of the thymus with Cushing's syndrome

A 29-yr-old male developed Cushing's syndrome with severe hypokalaemia, alkalosis and hypernatraemia. He died with Pseudomonas septicaemia and Nocardia pneumonia. At autopsy he was found to have a carcinoid tumour of the thymus which was not suspected before death, and marked bilateral hyperplasia of the adrenal cortex.
