CONTEXT Somatostatin-producing endocrine tumors of the duodenum are very rare neoplasms of the gastrointestinal tract. These tumors may be associated with von Recklinghausen's disease. CASE REPORT We present the case of a 49-year-old female patient with von Recklinghausen's disease and an incidentally diagnosed ampullary neoplasm. The patient was treated with a classical pancreaticoduodenecto...

OBJECTIVES To describe the biological behavior and surgical management of ampullary neuroendocrine tumors in 7 patients. DESIGN Case series and literature review. SETTING University hospital. PATIENTS Seven patients with ampullary neuroendocrine tumors. MAIN OUTCOME MEASURES Clinical presentation, pathologic findings, and survival. RESULTS The patients presented with jaundice (3 patie...

CONTEXT Metastases from ampullary malignancies are common, but spread to the testicle and paratesticular tissue is exceedingly rare with only 2 reported cases in the literature. CASE REPORT We report a case of a 70 year-old male with a history of ampullary adenocarcinoma status post pancreaticoduodenectomy who presented with a symptomatic right-sided hydrocele. Subsequent pathology revealed m...

The anamniote lateral line system, comprising mechanosensory neuromasts and electrosensory ampullary organs, is a useful model for investigating the developmental and evolutionary diversification of different organs and cell types. Zebrafish neuromast development is increasingly well understood, but neither zebrafish nor Xenopus is electroreceptive and our molecular understanding of ampullary o...

A 61-year-old woman was admitted for upper abdominal pain and fever. Laboratory findings showed raised neutrophil ratio and amylase and lipase levels. Abdominal computed tomography (CT) scan revealed diffuse swelling of the pancreas with peripancreatic fluid, and mild dilatation of the mid-pancreatic duct. Endoscopic retrograde cholangiopancreatography (ERCP) showed dimpling of the ampullary or...

Presenter: Yasmin Essaji MD | Virginia Mason Medical Center Background: Ampullary cancers are rare tumors accounting for approximately 6-7% of all periampullary cancers. True ampullary generally present at earlier stages owing to the rapid development obstructive jaundice. Due presentation and tumor biology, continually demonstrate longest median overall survival amongst tumors. Several retrosp...

Type I and type II hair cells of the vestibular system are innervated by afferents that form calyceal and bouton terminals, respectively. These cannot be experimentally cross-innervated in the inner ear to determine how they influence each other. However, analogous organs are accessible for transplantation and cross-innervation in the brown ghost electric fish. These fish possess three types of...

Hepatoid differentiation in pancreatic carcinoma is a rare phenomenon. It occurs either as a pure form or as a component with other subtypes. Herein, we report a 52-year-old man with an ampullary large cell neuroendocrine carcinoma presenting with obstructive jaundice for 2 months. A 0.5-cm nodule was found in the pancreatic head. Morphologically, the nodule was composed of exclusively hepatocy...
