For years some ecologists have been convinced that pesticides are contributing to a decline in amphibian species around the globe. From an apparent epidemic of deformed frogs in Minnesota to the near disappearance of yellow-legged frogs from California’s Sierra Nevada Mountains, pesticides have been considered prime suspects. This suspicion is no doubt rooted in the belief by the ecological com...

O adenoma da papila de Vater é uma lesão pré-maligna rara, com poucos casos descritos na literatura médica. seu tratamento controverso, podendo ser feito por excisão local conservadora ou endoscópica, duodenopancreatectomia radical. Os autores apresentam um caso papua Vater, sendo que esta foi achado endoscópico incidental em paciente portador adenocarcinoma gástrico. A tratada cirúrgica e papi...

Scrotal ectopia is a rare condition. Associated anomalies are common. We describe a neonate with ectopic scrotum with VACTERL association. This combination of anomalies is very rare.

There has been no report for the expression of cyclooxygenase-2 (COX-2) and its clinicopathologic and biologic significance in ampulla of Vater cancer. This study was aimed for the clarification of COX-2 expression and its biologic roles in ampulla of Vater cancer. Fourty-six patients with ampulla of Vater cancer were enrolled and their COX-2 expression and clinicopathologic features were analy...

BACKGROUND Neuroendocrine tumors (NETs) of the ampulla of Vater are rare and difficult to diagnose. We report a rare case of a small NET of the ampulla of Vater with metastasis to distant lymph nodes. CASE PRESENTATION The patient was a 54-year-old man complaining of epigastric pain and melena. Upper gastrointestinal endoscopy revealed a bulging papilla with active bleeding, which was diagnos...

PURPOSE Tumors arising from the ampulla of Vater can be benign or malignant. Recently, endoscopic papillectomy has been employed in the management of benign ampulla of Vater tumors; however, surgical resection is the treatment of choice. The aim of this study was to define indications and suggest a role for transduodenal ampullectomy in the management of ampulla of Vater tumors. METHODS We re...

The discovery of the accessory duct of the pancreas is usually ascribed to Giovanni Domenico Santorini (1681-1737), after whom this structure is named. The papilla duodeni (ampulla 'of Vater', or papilla 'of Santorini') is named after Abraham Vater (1684-1751) or after GD Santorini. Pancreas divisum, a persistence through non-fusion of the embryonic dorsal and ventral pancreas is a relatively c...

Carcinoma of the ampulla of Vater is a relatively rare neoplasm and its longterm survival rate is considerably high. However, because of differences in tumor pathologic features and local invasiveness, a 5-year survival rate differ widely. We present a case of metastatic carcinoma of the ampulla of Vater presenting as a Krukenberg tumor in a 59-year-old woman. Eight months earlier, she had been...
