Carcinoid Syndrome

Carcinoid syndrome (/kɑːrˈsɪnɔɪd/ kar-SIN-oyd) refers to a group of specific symptoms that occur as a result of carcinoid tumors, which are rare, slow-growing tumors that originate in cells of the body's neuroendocrine system.


The term "carcinoid" was first used in 1907 by the German pathologist Siegfried Oberndorfer. He used the term to describe tumors that seemed to be less aggressive than typical carcinomas. The term is derived from the Greek karkinos, meaning "crab", and the suffix -oid, meaning "like".


Symptoms of carcinoid syndrome can vary, but often include flushing, diarrhea, wheezing, and heart disease. These symptoms are caused by the carcinoid tumors secreting large amounts of hormones into the bloodstream.


Diagnosis of carcinoid syndrome often involves a combination of physical examination, medical history, and laboratory tests. These tests may include blood and urine tests to measure hormone levels, as well as imaging tests such as computed tomography (CT) scans and magnetic resonance imaging (MRI) to identify the presence and location of tumors.


Treatment for carcinoid syndrome typically involves managing the symptoms and treating the underlying carcinoid tumors. This may involve surgery to remove the tumors, medication to control hormone levels, and other therapies such as chemotherapy or radiation therapy.
