An advanced carcinoid tumor consumes large quantities of tryptophan, an amino acid which is necessary to make niacin. Therefore, a carcinoid tumor can cause the body to have a deficiency of niacin which may result in the disease pellagra. Pellagra is marked by a scaly rash, diarrhea, and dementia. Carcinoid tumors may also lead to heart disease, ulcers, Cushing's syndrome, and sexual dysfunction.
