Severe hypokalemia, metabolic alkalosis and hypertension in a 54 year old male with ectopic ACTH syndrome: a case report
نویسندگان
چکیده
Ectopic ACTH syndrome is a rare cause of Cushing's syndrome accounting for about 15% of all cases. Small cell lung cancer and bronchial carcinoids account for about half of the cases. Malignant neoplasm has rapid and more aggressive metabolic effects. We report a 54-year-old male patient with phenotypic features of Cushing's syndrome with severe hypokalemia, metabolic alkalosis, hypertension and altered mental status as manifestations of an ACTH-secreting small cell carcinoma from the lung. Ectopic ACTH syndrome should be highly considered in patients with hypertension and severe hypokalemic metabolic alkalosis, especially when a lung mass is discovered.

Introduction: Multiple endocrine neoplasia type IIa (MEN IIa) is an autosomal dominant syndrome characterized bypheochromocytoma ,medullary thyroid carcinoma and hyperparathyroidism. Pheochromocytoma approximately occurs in 50% of patients with MEN IIa. This tumor has the capacity to produce ACTH ectopically and becomes manifest like Cushing syndrome,although it is very rare. Case Report: We ...
متن کاملSevere hypertension and hypokalemia as first clinical manifestations in ectopic Cushing's syndrome.
Ectopic ACTH production occurs in about 10% of all cases of Cushing's syndrome, and about 25% of cases of ACTH-dependent Cushing's syndrome. Diverse tumor types are able to produce ACTH ectopically, including small cell lung carcinoma. Ectopic ACTH secretion by malignant neoplasm has been reported to have earlier and more aggressive metabolic effects. We report a 59-year-old male patient with s...

Abstract A 26 -year- old woman presented with rhabdomyolysis secondary to severe hypokalemia. Hypertension and metabolic alkalosis could lead to the suspicion of primary aldosteronism, which was confirmed by a decreased plasma rennin, elevated plasma aldosterone levels and high aldosterone/rennin ratio additionally. Additionally adrenal computed tomography showed an adrenal tumour. Blood press...
متن کاملA Case of Ectopic Adrenocorticotropic Hormone Syndrome in Small Cell Lung Cancer
Small cell lung cancer (SCLC), which originated from neuroendocrine tissue, can develop into paraneoplastic endocrine syndromes, such as Cushing syndrome, because of an inappropriate secretion of ectopic adrenocorticotropic hormone (ACTH). This paraneoplastic syndrome is known to be a poor prognostic factor in SCLC. The reason for poor survival may be because of a higher risk of infection assoc...

UNLABELLED Cushing's syndrome (CS) due to ectopic ACTH production accounts for about 10% of all types of CS and is frequently associated with metabolic alkalosis. Treatment of CS involves surgical resection and/or medical therapy to control hypercortisolism. We present the case of an 80-year-old woman affected by CS due to an unknown cause. The patient had severe metabolic alkalosis with refrac...
