Gangliocytic paraganglioma of the duodenum is an extremely rare disease. Few cases have been reported in the literature from 1957 to 2010. We reported a 67-year-old man with gangliocytic paraganglioma of the duodenum.

Somatostatinomas are rare functioning carcinoid tumors that usually arise in the pancreas and duodenum. They are seldom associated with typical clinical symptoms; their diagnosis is confirmed only by histological and immunohistochemical studies and the presence of specific hormones. Two distinct clinicopathological forms of somatostatinoma exist: duodenal and pancreatic somatostatinomas. Clinically, compared to pancreatic somatostatinomas, duodenal somatostatinomas are more often associated with nonspecific symptoms and neurofibromatosis, but less often with somatostatinoma syndrome or metastasis. Histologically, duodenal somatostatinomas frequently have psammoma bodies in the tumor cells. We report a case of duodenal somatostatinoma in 58-year-old man with vague epigastric pain and nausea. He did not have diabetes, steatorrhea, or cholelithiasis. Abdominal computed tomography showed a 25-mm mass in the duodenum and 25-mm nodule in the liver. Endoscopic retrograde cholangiopancreatography showed a duodenal submucosal tumor. Although the endoscopic biopsies were free of malignancy, the patient subsequently underwent Whipple's operation for the duodenal mass. Examination revealed as a somatostatinoma using a special stain for somatostatin.

Duodenal gangliocytic paraganglioma derived from neural crest is a peculiar neuroendocrine tumor. It is incidentally found during radiographic studies or due to gastrointestinal hemorrhage caused by frequent ulceration of the overlying mucosa. Most lesions are pedunculated and submucosal with distinctive histology consisting of endocrine cells, ganglion cells and spindle-shaped Schwann cells. We experienced a duodenal gangliocytic paraganglioma in a 40-year-old woman presenting with episodes of melena. Esophagogastroduodenoscopy revealed a submucosal ulcerated tumor in the second portion of duodenum and a biopsy confirmed gangliocytic paraganglioma. The tumor was enucleated through a duodenotomy. It's size was 5.5 X 3 X 1.5 cm sized and revealed positive cellular reaction for chromogranin, synaptophysin, neuron-specific enolase, and neurofilament by immunohistochemistry. The majority of the reported duodenal gangliocytic paraganglioma were of benign nature. Therefore, radical surgery or a lymph node dissection could be avoided if that disease was confirmed. However, thorough investigation for lymph node metastasis and postoperative follow-up are needed. We report the first case of a duodenal gangliocytic paraganglioma in Korea with a review of literature.

Duodenal-type follicular lymphoma (DFL) is a unique subtype of follicular lymphoma (FL), which often involves the second portion of duodenum (descending part of duodenum). Due to its specific pathological features, such as lack of follicular dendritic cells meshwork and disappearance of activation-induced cytidine deaminase expression, DFL presents an inert clinical course and is often confined to the intestinal tract. Inflammation-related biomarkers suggest that the microenvironment may play a likely role in the pathogenesis and favorable prognosis of DFL. Since patients generally have no obvious clinical symptoms and low progression rate, the treatment regimen for DFL is mainly observation and waiting (W&W) strategy. This study will review the latest research progress of epidemiology, diagnosis, treatment and prognosis of DFL in recent years.

OBJECTIVETo investigate the clinical characteristics, surgical procedures and prognosis of duodenal gastrointestinal stromal tumors (GISTs).

METHODSThe clinical data of 18 GIST patients, collected from 1995 to 2004, were retrospectively analyzed.

RESULTSThe lesions of duodenal GISTs mainly located in the descending duodenum (13/18), unusually in the horizontal part (2/18), ascending part (1/18), and the bulb (2/18). Pathological examination revealed 1 case of benign tumor, 2 cases of borderline tumors and 15 cases of malignant tumors, Microscopically, the tumors were composed of spindle cells (14 cases), epithelial cell (1 case), and mixed cell types (3 cases). The clinical manifestations were non-specific, mostly was melena (7/18), as well as abdominal pain (6/18), fullness (5/18), and anemia (3/18). The diagnoses were performed by upper gastrointestinal radiography, gastroscopy, endoscopic ultrasonography and CT scan. All of the 18 patients received surgical treatment, including 9 pancreaticoduodenectomies, 5 local resections, 3 segmental resections of duodenum, and 1 distal subtotal gastrectomy. 1 and 3 year survival rates were 100% and 86.7% respectively.

CONCLUSIONMost duodenal GISTs are malignant, and the choices of surgical procedures are mainly determined by the location and size of the tumors.
