Abstract:
Carcinoid tumors are well-differentiated epithelial neoplasms that usually can be diagnosed without difficulty based on their distinctive histologic patterns. These tumors are composed of variable numbers of calls that contain endocrine secretory granules in their cytoplasm, which can be identified by histochemistry, immunohistochemistry, and electron microscopy, Carcinoid tumors of the duodenum are relatively rare, the reported incidence being 2.0-8.9% of all gastrointestinal carcinoid tumors dianosed in Western countries. The rate of occurrence among all duodenal tumors is 3-5.5%. We experienced a case of carcinoid tumor of the duodenum in a 53 year-old male patient. He was admitted to our hospital because of epigastric pain. On the gastrofiberscopic examination, 0.7 cm sized Yamada type II polyp with central ulceration was noticed on the duodenal bulb. The biopsy specimen revealed carcinoid tumor. He was treated with polypectomy.
