Carcinoid tumor of stomach continue to interest clinician because of the rarity and difficulty in diagnosis clioically with infrequent classical carcinoid syndrome. Recently, we experienced a case of gastric carcinoid with hemetemesis and melena. We feel that this case is an instructive example of the fascinating variety of entities which can result in massive upper gastrointestinal bleeding. So we present this case with s review of relevant literatures.

We evaluated CT findings of bronchial carcinoid and accuracy of preoperative pathological diagnosis according to two subtypes. The subjects were 10 cases (typical;5, atypical;5), confirmed by surgery and tissue pathology. Sputum cytology (n=10), percutaneous aspiration (n=1) and bronchoscopic biopsy (n=8) were performed, preoperatively. The CT findings were analysed according to two subtypes. Typical carcinoid shows central location in all, and bronchial lumens just proximal to tumor were widened in two, whereas atypical carcinoid presented as peripheral leison in two. Among central atypical carcinoid, two cases showed flat meniscus appearance of lumen. Remaining one showed diffuse wall thickening. Intratumoral low density by necrosis was noted in one. Both subtypes show contrast enhancement. For preoperative diagnosis, sputum cytology & percutaneous aspiration were not conclusive at all. As for bronchoscopic biopsy, only 3 cases were accurately diagnosed as typical carcinoid. Typical carcinoid presented as endobronchial mass in all, whereas atypical carcinoid presented in various appearance. In all atypical & some typical carcinoid were misdiagnosed as primary lung cancer, preoperatively. However, in typical carcinoid, conservative surgery was possible. In conclusion, if there is discrepancy between CT findings & preoperative pathological diagnosis, full understanding of CT findings of bronchial carcinoid is imperative to choose appropriate surgical modality.

Primary mixed carcinoid with mucinous tumor of borderline malignancy of the ovary is very rare ovarian tumor. Most of them arose in dermoid cyst or in mature solid teratoma. Its diagnosis was based on histological and immunohistochemical findings. We experienced a case of primary mixed carcinoid postoperatively and present with a brief review of literatures.

A Carcinoid tumor of the ampulla of Vater is extremely rare, accounting for less than 0.3% of all gastrointestinal carcinoids. Most reported cases have arisen from the gallbladder. An ampullary carcinoid most commonly presents with jaundice or upper abdominal discomfort, and bleeding from the tumor is exceedingly rare. A diagnosis is most frequently made postoperatively due to submucosal spread of the tumor. As the metastatic potential cannot be predicted by tumor size, a Whipple pancreaticoduodenectomy rather than local excision is considered the treatment of choice. We herein report a case of a primary carcinoid tumor located at the ampulla of Vater that presented as gastrointestinal bleeding; the tumor was diagnosed by an endoscopic biopsy after a papillary sphinterotomy.

Carcinoid tumors originate from the neuroendocrine cells throughout the body and occur most frequently (74%) in the gastrointestinal tract. The clinical course is often indolent but can also be aggressive and resistant to therapy. Clinical manifestations are often vague or absent. Nevertheless, in approximately 10% of patients, the tumors secrete bioactive mediators which may engender various elements of characteristic carcinoid syndrome. In many instances, the neoplasms are detected incidentally at the time of surgery for other gastrointestinal disorders. The tendency for metastatic spread correlates with tumor size, and is substantially higher in lesions larger than 2.0 cm. Management of patients with carcinoid tumors requires an understanding of the disease process and a multimodality approach. Treatment consists of radical surgical excision of the tumor, although gastric (type I and II) and rectal carcinoids may be managed with local excision. However, advanced carcinoid tumor remains incurable.

A case of laryngeal carcinoid in a 54-year-old Korean female is reported and discussed. This tumor is extremely rare in the larynx and there have been just over twenty cases reported in the literature to date. The case showed an initial histologic finding of epithelial dysplasia and was finally confirmed to be a carcinoid tumor. Laryngeal carcinoids are often atypical histologically and may be misdiagnosed as undifferentiated carcinoma. An electron microscopic study revealed neurosecretory-type granules. Although the patient underwent a total laryngectomy and radical neck dissection, multiple hepatic metastasis was noted postoperatively.
