Cushing syndrome from an ACTH-producing pheochromocytoma or paraganglioma: structured review of 94 cases.

Adrenocorticotropic hormone-producing pheochromocytomas/paragangliomas are rare neuroendocrine tumors that co-secrete excess catecholamines and adrenocorticotropic hormone, resulting in Cushing syndrome (CS). This review aims to summarize important patient characteristics, investigations, and outcomes in all cases reported in the English literature. A literature search was conducted to identify all English-language case reports and case series describing adrenocorticotropic hormone-producing pheochromocytomas/paragangliomas.

Use of perioperative telotristat in a patient with carcinoid heart disease.

Summary: Carcinoid heart disease is a rare complication of carcinoid syndrome, resulting in right-sided valvular heart disease and subsequent heart failure due to long-term exposure to vasoactive substances. The management of this condition is complex, often requiring surgical intervention. Current perioperative regimens entail the use of prophylactic somatostatin analogs to prevent carcinoid crisis; however, regimens vary widely among practitioners and evidence supporting their efficacy in this clinical setting is mixed.

Radiation Exposure from GEP NET Surveillance.

Background: Neuroendocrine tumors (NET) are neoplasms that secrete peptides and neuroamines. For gastroenteropancreatic (GEP) NET, surgical resection represents the only curative option. Ten-year imaging surveillance programs are recommended due to long time-to-recurrence following resection.
