Carcinoid

Carcinoid

Carcinoid (/kɑːrsɪnɔɪd/), also known as carcinoid tumor, is a type of neuroendocrine tumor that originates from the neuroendocrine cells. The term "carcinoid" was first coined in 1907 by Oberndorfer, a German pathologist, from the Greek words karkinos meaning cancer and -oid meaning like, due to its cancer-like appearance.

Etymology

The term "carcinoid" is derived from the Greek words karkinos, meaning cancer, and -oid, meaning like. It was first used by Oberndorfer in 1907 to describe tumors that appeared cancer-like but behaved in a less aggressive manner.

Definition

Carcinoid tumors are slow-growing tumors that are part of a group of tumors called neuroendocrine tumors. They primarily occur in the gastrointestinal tract and lungs, but can also be found in other parts of the body such as the pancreas, ovary, and testes.

Symptoms

Symptoms of carcinoid tumors can vary greatly depending on the location of the tumor. Common symptoms include flushing, diarrhea, wheezing, and abdominal pain. In some cases, carcinoid tumors can lead to carcinoid syndrome, a group of symptoms that include flushing, diarrhea, and wheezing.

Diagnosis

Diagnosis of carcinoid tumors often involves a combination of medical history, physical examination, laboratory tests, and imaging studies. In some cases, a biopsy may be needed to confirm the diagnosis.

Treatment

Treatment options for carcinoid tumors depend on the size and location of the tumor, as well as the patient's overall health. Treatment options may include surgery, chemotherapy, radiation therapy, and hormone therapy.
