A case of a hyperaldosteronism and ectopic secretion of adrenocorticotropic hormone associated with small cell lung cancer is presented. A 59-year-old patient was studied for a constitutional syndrome diagnosing a metastatic small cell lung cancer. In the course of the oncological process, he manifests a clinic of hypertension, hypernatremia and hypokalemia. After a hormonal study he is diagnosed with a paraneoplastic hyperaldosteronism that is controlled with antihypertensives and antialdosteronics. The patient finally died due to liver progression of his tumor disease.esAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Small cell lung cancerHyperaldosteronismACTHHypertensionHypokalemiaresearch articleopen access10.24875/j.gamo.20000070https://doi.org/10.24875/j.gamo.20000070672833700033
