Abstract
A case of reticulum cell sarcoma which is very rare in the duodenum was reported in this paper. A 63-year-old man was first seen Oct. 9th 1974, because of 3 months duration of epigastralgia and vomitting. The physical examinations disclosed right hypochondrial tenderness, but tumor was not palpable. Barium meal duodenogram revealed a longitudinal crater with irregular contour in the oral half portion of C-loof along the inside and several polypoid lesions on the mucosa close to the crater. Rentogenological impression was a malignant tumor of the duodenum or encroached cancer of the head of pancreas to the duodenum. Duodenoscopic examination also showed a largecrater with irregular margin and yellow and white floor with blood clots which strongly impressed malignancy. Histologic diagnosis of the biopsy specimen from the duodenal wall was reported as reticulum cell sarcoma. Cytodiagnosis by aspiration method was malignant lynphoma. The patient underwent operation on Nov. 26th 1974. Histopathological studies of the resected material exactly coinsided with preoperative diagnosis. Postoperative course was uneventful. The patient was discharged on Dec. 24th 1974, and is in satisfactory condition now three months after the operation.
