The authors report a case of an ectopic ACTH-syndrome that resulted in severe hypercortisolism, hypokalemia, diabetes mellitus and osteoporosis. The ACTH-secreting tumor tissue was localized in the lung. The tumor was removed by segmentectomy and histological evaluation revealed an ACTH-secreting neuroendocrine tumor. After surgery, however, plasma cortisol and ACTH levels failed to decrease significantly due to subtotal tumor removal. Long-acting somatostatin analogue therapy resulted in a normalization of both plasma cortisol and ACTH levels and the clinical symptoms improved significantly. Residual tumor was removed by repeat surgery and the patient was permanently cured. Orv. Hetil., 2011, 152, 403-406.

Cushing's syndrome caused by an ectopic tumour secreting adrenocorticotropic hormone (ACTH) is not common. Furthermore, an ACTH-secreting panreatic neoplasm is extremely rare. We present a 27-year old...
Ectopic adrenocorticotropic hormone (ACTH) syndrome is characterized by hypercortisolism due to the hypersecretion of a non-pituitary ACTH-secreting tumor leading to Cushing's syndrome. Only a few cas...
Cushing's syndrome is caused by excessive adrenocorticotropic hormone (ACTH) secretion derived from pituitary corticotroph tumors (Cushing disease) or from non-pituitary tumors (ectopic Cushing's synd...
Ectopic thyrotropin (TSH)-secreting pituitary adenomas are rare and can often be misdiagnosed as primary hyperthyroidism. We present a case of an ectopic suprasellar TSH-secreting pituitary adenoma. A...
The purpose of this prospective open-label phase II study, is to evaluate the efficacy of pasireotide twice daily subcutaneous injections for normalizing 24 hour urine free cortisol in pat...
Cushing Syndrome is an endocrine disorder causing an over production of the hormone cortisol. Cortisol is produced in the adrenal gland as a response to the production of ACTH in the pitu...
RATIONALE: Rosiglitazone may help pituitary tumor cells become more like normal cells, and to grow and spread more slowly. PURPOSE: This phase II trial is studying how well rosiglitazone ...
This study will evaluate whether the drug mifepristone can improve the symptoms of Cushing's syndrome in people with ectopic adrenal corticotrophin hormone (ACTH) secretion. Cushing's synd...
In an attempt to simplify the diagnosis of ectopic pregnancy, the researchers will investigate the presence of specific molecular markers of ectopic pregnancy. The quantification of these...
Tumors whose cells possess secretory granules and originate from the neuroectoderm, i.e., the cells of the ectoblast or epiblast that program the neuroendocrine system. Common properties across most neuroendocrine tumors include ectopic hormone production (often via APUD CELLS), the presence of tumor-associated antigens, and isozyme composition.
A GASTRIN-secreting neuroendocrine tumor of the non-beta ISLET CELLS, the GASTRIN-SECRETING CELLS. This type of tumor is primarily located in the PANCREAS or the DUODENUM. Majority of gastrinomas are malignant. They metastasize to the LIVER; LYMPH NODES; and BONE but rarely elsewhere. The presence of gastrinoma is one of three requirements to be met for identification of ZOLLINGER-ELLISON SYNDROME, which sometimes occurs in families with MULTIPLE ENDOCRINE NEOPLASIA TYPE 1; (MEN 1).
Symptom complex due to ACTH production by non-pituitary neoplasms.
A syndrome characterized by HYPERPIGMENTATION, enlarging pituitary mass, visual defects secondary to compression of the OPTIC CHIASM, and elevated serum ACTH. It is caused by the expansion of an underlying ACTH-SECRETING PITUITARY ADENOMA that grows in the absence of feedback inhibition by adrenal CORTICOSTEROIDS, usually after ADRENALECTOMY.
A group of carcinomas which share a characteristic morphology, often being composed of clusters and trabecular sheets of round "blue cells", granular chromatin, and an attenuated rim of poorly demarcated cytoplasm. Neuroendocrine tumors include carcinoids, small ("oat") cell carcinomas, medullary carcinoma of the thyroid, Merkel cell tumor, cutaneous neuroendocrine carcinoma, pancreatic islet cell tumors, and pheochromocytoma. Neurosecretory granules are found within the tumor cells. (Segen, Dictionary of Modern Medicine, 1992)
