The tumor was localized endo-scopically after an attack of melena. There were no signs of endocrinopathy. A local resection with suturing of the pancreatic duct was performed. Morphologically, there were two different tissue types (neurogenous and carcinoid-like) with numerous cells and nerve fibers reacting immunohistochemically with somatostatin and neurotensin antisera: some immunoreactivity to PP-antibodies was observed. Still, after 20 months, the patient seems to have been cured by local resection.<\/jats:p>","DOI":"10.1159\/000199178","type":"journal-article","created":{"date-parts":[[2009,1,31]],"date-time":"2009-01-31T12:11:36Z","timestamp":1233403896000},"page":"54-59","source":"Crossref","is-referenced-by-count":48,"title":["A Metastatic Endocrine-Neurogenic Tumor of the Ampulla of Vater with Multiple Endocrine Immunoreaction Malignant Paraganglioma?"],"prefix":"10.1159","author":[{"given":"M.","family":"B\u00fcchler","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Malfertheiner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Baczako","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.","family":"Krautzberger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.G.","family":"Beger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,1,28]]},"container-title":["Digestion"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/199178","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000199178","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T08:17:00Z","timestamp":1777537020000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000199178"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,1,28]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000199178","archive":["Portico"],"relation":{},"ISSN":["0012-2823","1421-9867"],"issn-type":[{"value":"0012-2823","type":"print"},{"value":"1421-9867","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,1,28]]}}}
