title: [Multicystic chylous lymphangioma in the mesentery of the small intestine].
abstract: In the search for metastases computed tomography and ultrasonography of the abdomen were performed in a 47-year-old man with a known malignant melanoma in the left lower leg. Numerous fluid-filled cavities, about 8 cm in diameter, were an incidental finding. He died two years after diagnosis of the melanoma, which had extensively metastasized. At autopsy a large multicystic tumour (21 x 15 x 8 cm) was found in the mesentery of the small intestine. The cysts were filled with chyle. Histologically they proved to be multicystic lymphangiomas. Mesenteric lymphangiomas are very rare, multicystic ones and manifestation in adults even more so.
