Low grade lesions: Carcinoid tumors are neuroendocrine tumors found in many organs of the body. Commonly they are found in the GI tract but can appear in the lung or even pancreas (Steve Jobs). The tumors are derived from endocrine cells producing hormone-like substances and resemble neurons secreting neurotransmitters. There are two types of lung carcinoid tumors: typical and atypical. In lung, typical carcinoids account for about 9 out of 10 lung carcinoids. They grow slowly and rarely spread beyond the lungs. Atypical carcinoids are much rarer. They grow somewhat faster and have a greater chance for metastasis..

A 24-year-old member asked:

Are carcinoid tumors benign?

Dr. Shelby Terstriep

No: Carcinoid tumors are not benign. They are typically (but not always) slower growing than other tumors. They can spread if not found and therefore should be removed.
A member asked:

Are the symptoms of carcinoid tumors bad?

Dr. Scott Welker

Not always!: The most common place to have a carcinoid is the appendix. When the tumor is there, and most of the other common locations which are in the intestinal tract, you don't feel anything because the liver removes the hormones the tumors produce. Only when the tumors are large, outside the intestinal tract, or metastatic do the symptoms occur. They can get very bad then.

"low" malignant potential, but can be aggressive, spread; can cause abd pain, ;"syndrome" with flushing, wheezing, murmurs, etc. Small ones can be cured by surgical removal; may need chemo, embolization, or octreotide rx for symptom control.

What are carcinoid tumors / syndrome?

1 doctor answer4 doctors weighed in
Dr. Jason Sample
General Surgery 24 years experience
Neuroendocrine tumor: It is a relatively benign type of tumor that can secrete a variety of hormones, most notably serotonin. They are most commonly found in the gut or the lungs. They do not come from the lining of the lungs or the gut (as adenocarcinomata do). They come from a different line of cells. Carcinoid syndrome occurs when large amounts of serotonin get into the bloodstream, assoc with flushing and diarrhea.
A 48-year-old member asked:

What is the difference between typical and atypical carcinoid?

1 doctor answer1 doctor weighed in
Dr. Sewa Legha
Medical Oncology 50 years experience
Difference in Grade: These are two terms used by pathologists to make a distinction between well differentiated carcinoid(called typical) and less than well differentiated or high grade carcinoid(called Atypical carcinoid) which is more common in bronchial carcinoids. One reason for making this distinction is for chemotherapy which is not useful in typical but tends to be more effective in Atypical carcinoids
