Retroperitoneal germ cell tumor mimicking neoplasm of ampulla of Vater

Endoscopic management of ampulla of Vater tumor

Tumors of the ampulla of Vater can cause symptoms and signs of abdominal pain, jaundice, anemia due to occult gastrointestinal bleeding, recurrent pancreatitis, abnormal liver function tests, biliary or pancreatic duct dilation on imaging studies. Traditional treatments for ampullary tumors are surgical approaches, including transduodenal local resection or pancreaticoduodenectomy (PD). The for...

Gastrointestinal stromal tumor of the ampulla of Vater.

Carcinoid of ampulla of Vater.

Carcinoid tumors of ampulla are rare clinical entities. They form 0.35% of all the gastrointestinal carcinoids. So far, only 109 cases have been reported in the literature, mostly as individual case reports. Since the metastatic potential and the tumor size have no correlation, unlike in duodenal carcinoids, pancreatoduodenectomy is considered the treatment of choice. Here we present a case of ...

Ectopic pancreas Ampulla of Vater Periampullary tumor Total ampullectomy Sphincterotomy

Ectopic pancreas is an uncommon condition and is usually found in the gastrointestinal tract, such as stomach, duodenum and jejunum. However, ectopic pancreas in the ampulla of Vater is rare and its clinical presentations may be similar to periampullary cancer. It is difficult to diagnose preoperatively. We present such a case where the diagnosis was proven postoperatively. Our patient, a 51-ye...

Retroperitoneal Leiomyosarcoma Associated with an Elevated β-HCG Serum Level Mimicking Extragonadal Germ Cell Tumor

Patient. A 65-year-old man was admitted with a large primary retroperitoneal tumor and an increased beta-human chorionic gonadotropin (beta-HCG) serum level. A germ cell tumor was suspected; however, a computed tomography-guided biopsy failed to enable tumor classification. After two courses of chemotherapy, the beta-HCG serum level had returned to the normal level and a diagnostic laparotomy w...
