File:IPLab7Carcinoid3.jpg|This is a high-power photomicrograph of the surgical specimen showing the tumor's growth pattern--cells form discrete islands, trabeculae, and glands.
File:IPLab7Carcinoid4.jpg|This is a high-power photomicrograph of the surgical specimen showing the cellular morphology. The tumor cells are monotonously similar with scant, pink, granular cytoplasm and a round-to-oval stippled nucleus. As in most carcinoid tumors, there is minimal variation in cell and nuclear size, and mitoses are infrequent or absent.

 * <spoiler text="What is 'carcinoid syndrome' and how common is it?">Carcinoid syndrome occurs in about 1% of all patients with carcinoids and in 20% of those with widespread metastases. Uncertainties remain about the precise origin of the carcinoid syndrome, but most manifestations are thought to arise from excess elaboration of serotonin. The clinical syndrome can include cutaneous flushes and apparent cyanosis; intestinal hypermotility (diarrhea, cramps, nausea, vomiting); asthmatic bronchoconstrictive attacks; hepatomegaly (due to metastases); systemic fibrosis (cardiac, aortic, retroperinoteal. pelvic).</spoiler>
 * <spoiler text="What is the prognosis for patients with carcinoid tumors?">The overall 5-year survival rate for carcinoid tumors (excluding appendiceal) is approximately 90%. Even with small bowel tumors and hepatic metastases, there is a 50% 5-year survival. Widespread disease, however, usually causes death.</spoiler>

		+	== Clinical Summary ==
		+	This 58-year-old male experienced increasing diarrhea (up to 10-12 yellow watery stools per day) over the year prior to admission. During this period he experienced a weight loss of 40 pounds. A laparotomy was performed after a careful workup.
		+
		+	== Autopsy Findings ==
		+	The operative specimen consisted of 12 cm of distal ileum, appendix, cecum and 50 cm of colon. The ileum was mildly dilated and its wall hypertrophied. On opening the bowel there was a 4.5 x 3 x 3-cm elliptical submucosal mass at the ileocecal valve; this had produced partial obstruction. Several small (2 mm) submucosal masses were found in the cecum nearby. On cut section each lesion was found to be firm, gray-tan and homogeneous involving the muscular wall of the bowel and adjacent mesentery. The appendix and colon showed no lesions.
