title: Carcinoid somatostatinoma of the duodenum.
abstract: Carcinoid somatostatinoma is a rare neuroendocrine malignant tumour and the duodenal location is an atypical site of presentation of which only few cases have been reported in the literature. A case of duodenal carcinoid somatostatinoma metastatic to lymph nodes in a 66-year-old patient is presented with an update of the literature. No relevant signs or symptoms were associated to the retrogastric lymph-node mass, which deformed but did not infiltrate the stomach wall. At the first and third portion of the duodenum, two polipoid endoluminal nodules (size 1 cm) were found with adjacent adenopathy partially adherent to the head of the pancreas and with thickening of the antropyloric wall. The patient underwent antrectomy duodenum mobilization and lymphadenectomy in the hepatic artery region. The treatment was successful and, over 3 years after diagnosis, there has been no clinical or radiological evidence of relapse. Duodenal somatostatinoma is rare and its diagnosis is often incidental. Surgery would be the appropriate treatment in the early stage of the disease with good chances of cure.
