PRIMARY DUODENAL ADENOCARCINOMA The primary carcinoma of the duodenum constltutes 0.3 to 0.5% of ali the digestive neoplasms and 33 to 45% of those of the small intestine. The authors descrlbe the case of a 68-year old man who had presented itching for three month and fever and vomlting for one month. At hospitalizatlon, he had neither jaundice nor a palpable mass. Bilirubinemia levels were normal, the alkaline phosphatase was increased and the transaminase and GT levels were slightly altered. Ecography showed dllation of ali the billary tract without gallstones. The CT scan was negative. At hypotonic duodenography, the contrast medium did not completely fili the second portlon of the duodenum near the papllla extendlng to the lower knee. After opening the duodenum, a vegetatlng mas In the second portion of the duodenum was found. The Intraoperative cholanglography showed a marked dllatlon of the billary ducts. The patient was therefore submitted to a duodenocephalopancreatectomy. The histological examination showed a dlfferentiated adenocarcinoma from an originai viilous adenoma. The patlent dled on the 41st day of an atrlal flutter and serlous thrombocytopenla, reslstant to Intensive and transfuslonal therapy. The atyplcal characteristlcs of the symptoms of thls case are stressed. The dlagnostics is based on the ecography, hypotonic duodenography and endoscopy. The treatment calls for the duodenocephalopancreatectomy wlth radical intents or a palliatlve gastrojejunal bypass.
