The rare case of carcinoid tumor in mid ileal segment causing intestinal obstruction.

Abstract

Carcinoids are rare neuroendocrine tumors (NETs) that are thought to arise from the enterochromaffin (Kulchitsky) cells found in the Lieberkuehn crypts of the intestinal gut. The term enterochromaffin refers to the ability to stain with chromium salts, a common feature of 5-HT-containing cells. The median age is 63 years. Using barium examinations, carcinoid tumors of the small intestine and colon can be found as polypoidal or ulcerated masses, submucosal filling deficiencies, or both. As the main indicator of a neuroendocrine tumor's potential for malignancy, consider tumor differentiation. Increased production of peptides, neuroamines, and other vasoactive compounds defines this condition. A detailed medical history and a thorough physical examination should be carried out before the operation. Many of the cases may be overlooked or missed during routine examinations. Diagnosis by radiological and biochemical markers (5-hydroxy-indole-acetic acid (5-hiaa) and chromogranin A (CgA). will be helpful to keep the location of pathology in mind during the intraoperative phase. Therefore, we report this case to draw attention to this rare entity and to consider it as a differential diagnosis when dealing with a case of abdominal pain in a primary health care setting, where presentation of abdominal pain is quite common.
