Villous adenoma of the ampulla of Vater Which is sometimes the cause of extrahepatic obstructive jaudice is uncommon disease. But they are important in spite of their rarity, because of frequent malignant change in the tumor as a focal or all occult tumor. Recently, the early diagnosis of ampullary tumors has become possible due to the ide application of fiberoptic endoscopy and increasing knowledge about the ampullary tumors. Although the biopsies were taken during the endoscopy, sometimes one might miss the area of malignant degeneration. But, it could increase the diagnostic accuracy by performing a hiopsy at the highly suspected site ofl malignancy, like our case in which fixed and discolorecl areas in the lesion were biopsied. So we recommed an affn.ssive endoscopic study and hypotonic duodenogram. Even thought it is diagnosed as benign, and can be treated with endoscopic pelypectorny, but we recommend the complete resection of the tumor because of high incidence of recurrence and malign ant transformati on.

Aneurysms of the hepatic artery are uncommon lesions in comparison to those in other major vessels. Their clinical symptomatology varies from symptomless to shock due to rupture and most are noticed in the fatal course of rupture. So early diagnosis and prompt treatment are very difficult and important. A 48-year-old male was admitted due to hematemesis and steady abdominal pain. By duodenoscopy, hemobilia was suggested from the blood clot on the orifice of the ampulla of Vater and the celiac angiography was performed, which revealed a hepatic artery aneurysm. We performed selective hepatic artery embolization, thereafter the patients symptoms were relieved.
