A 66 year old female was found to have an ampullary mass on endoscopic examination. A pancreaticoduodenectomy was performed and the pathology was consistent with carcinoid tumor. Carcinoid tumors of the ampulla of Vater are rare tumors of the gastrointestinal tract, accounting for 0.3-1% of gastrointestinal carcinoids. Management of ampullary carcinoid tumor with pancreaticoduodenectomy is in a...

Goblet cell carcinoid tumor is a rare clinical entity which is usually diagnosed either as acute appendicitis or advanced cancer. Its main characteristic is that the histological findings are between those of adenocarcinoma and typical carcinoid tumor of the appendix. Goblet cell carcinoid tumors appear almost exclusively in the appendix, and prognosis depends mainly on the stage and the subtyp...

The carcinoid tumor is a relatively rare type of endocrine tumor, which arises mainly in the gastrointestinal tract. Primary gallbladder and biliary duct system carcinoids comprise less than 1% of all carcinoid tumors arising from any tissue or organ in the body. We describe a case of carcinoid tumor of the gallbladder in a 39-year-old man. There have been only 32 cases described in the literat...

BACKGROUND Carcinoid tumors are slow growing neuroendocrine tumors which can originate from various sites within the body. A carcinoid tumor originating in the medulla spinalis has not previously been reported in the literature. CASE REPORT We report a case of a 33-year-old man, presenting with a five-month history of bilateral lower extremity pain, as well as paresthesia, and mild weakness i...

Adenocarcinoma ex goblet cell carcinoid is a rare neoplasm of appendiceal origin that contains features of both carcinoid tumor and adenocarcinoma. We report on a case of a 45-year-old woman, post-renal transplant who presented with ovarian metastases from this tumor. This appears to be the first report of an adenocarcinoma ex goblet cell carcinoid in a renal transplant recipient.

Primary carcinoid tumors of the nasal cavity and sinuses are exceedingly rare. An accurate histopathological diagnosis is crucial to optimal investigation and management. We present a case of a primary atypical carcinoid tumor arising from the sphenoid rostrum without evidence of associated carcinoid syndrome. This rare but important differential diagnosis of a nasal tumor is discussed and impo...

Carcinoid tumors comprise an uncommon group of pulmonary neoplasms with neuroendocrine origin. In comparison with typical carcinoid tumors, atypical tumors are less common and more aggressive. We present a 35-year old female with atypical carcinoid tumor. The mass was located centrally and transsternal pneumonectomy was performed to resect the tumor.

Esophageal carcinoid tumors remain some of the rarest of all carcinoid tumors, with only several cases previously reported in the literature. The endoscopic mucosal resection of selected carcinoid tumors has been shown to be a valid, safe, and effective method of treatment. Endoscopic ultrasonography is the technique of choice to select patients eligible for endoscopic resection. Here, we repor...

Neuroendocrine tumors, such as carcinoids, are highly metastatic neoplasms that secrete bioactive hormones resulting in carcinoid syndrome. Few curative treatments exist outside of surgical resection. We have previously shown that activation of the Raf-1 signaling pathway can suppress hormone production in carcinoid tumor cells. In this study, we investigated a novel treatment for carcinoid tum...

A strumal carcinoid arising in a benign cystic teratoma of the left ovary was reported in a 41 year-old woman. The solid tumor was histologically a trabecular carcinoid tumor associated intimately with thyroid follicle-like structures. By Grimelius staining, argyrophil granules were found in the cytoplasm of the tumor cells. The final diagnosis of strumal carcinoid, however, was established by ...
