Abstract

<p>A rare case of jejunal mesenteric lymphangioma involving the pancreas in a 60-year-old man is reported. A cystic lesion about 9 cm in diameter was detected by abdominal ultrasonography in the patient at the onset of colonic diverticulitis. The patient was referred to our hospital for further examination. Follow-up was initiated, since lymphangioma was suspected. Six years later, a medical check-up showed a tumor mass greater than 11 cm in diameter, and the patient was again referred to our hospital. Abdominal computed tomography showed a multilocular tumor in the right side of the abdomen. Considering the possibility that the mass might have been malignant, laparotomy was performed. The tumor was found in the mesentery of the jejunum and involved the uncinate process of the pancreas. Therefore, tumor removal with partial resection of the pancreas was performed using an automatic suturing device. The final pathological diagnosis was lymphangioma of the jejunal mesentery involving the pancreas, which is rarely observed in adults. The findings of the present case are discussed in the context of the relevant literature.</p>
