[Primary tumours of the mesentery. Study of four cases (author's transl)]

The authors report four cases of mesenteric tumour including one cavernous lymphangioma complicated by volvulus of of the small intestine and one angiofibroma, a benign solid tumour which is rarely encountered. They comment on the preoperative assessment, which is not always possible for these patients are often operated on as an emergency. Cysts are easy to remove, but solid tumours even when benign are much more difficult to remove.
