Palliative therapy of an ectopic Cushing's syndrome due to a metastatic carcinoid tumor.

The case of a 39-year-old patient with ectopic Cushing's syndrome due to a metastatic carcinoid tumor is presented. Palliative therapy consisting of 800 mg ketoconazole and 0.3 mg SMS 201-995/die resulted in clinical remission and correction of hypokalemia and hypercortisoluria. Combined therapy was clearly superior to monotherapy with ketoconazole or SMS 201-995, respectively. Side effects were not observed, the tumor masses remained unchanged throughout the observation period of now 19 months.
