carcinoid

adj. cancerous

Carcinoid (also carcinoid tumour or carcinoid tumor) is slow-growing but often malignant type of neuroendocrine tumour, originating in the cells of the neuroendocrine system. Carcinoid tumours are apudomas that arise from the enterochromaffin cells throughout the gut. They are most commonly found in the foregut (35.6 ases) with lung, bronchus and trachea constituting 27.9 ases from where they rarely metastasise (except in case of pancreas). The next most common affected area is the small intestine especially the midgut (32.1 ases) with the highest proportion from ileum at 14.9% of all cases [as per the PAN-SEER data (1973-1999)]. In cases of metastases it can lead to carcinoid syndrome. This is due to the production of 5-hydroxytryptamine, which is released into the systemic circulation, which leads to symptoms of cutaneous flushing, diarrhea, bronchoconstriction and right-sided cardiac valve disease.

(hypernym) tumor, tumour, neoplasm

[KAR-sin-oyd]
A slow-growing type of tumor usually found in the gastrointestinal system (most often in the appendix), and sometimes in the lungs or other sites.Carcinoid tumors may spread to the liver or other sites in the body, and they may secrete substances such as serotonin or prostaglandins, causing carcinoid syndrome.

[KAR-sin-oyd]
A combination of symptoms caused by the release of serotonin and other substances from carcinoid tumors of thegastrointestinal tract. Symptoms may include flushing of the face, flat angiomas (small collections of dilated blood vessels) of the skin, diarrhea, bronchial spasms, rapid pulse, and sudden drops in blood pressure.
