Carcinoid tumors are of neuroendocrine origin and derived from primitive stem cells in the gut wall, but they can be seen in other organs, [5] including the lungs, [6] mediastinum, thymus, [7] liver, pancreas, bronchus, ovaries, [12] prostate, [13] and kidneys [26] (see the image below). While carcinoid tumors have a tendency to grow slowly, have a high potential for metastasis.
