[Carditis as a rare complication of ulcerative colitis].

It is reported on a 24-year-old patient with ulcerous colitis, in whom a severe peri-myocarditis appeared two weeks of the beginning of an acute episode. With reference to reports of analogous courses in literature a causal connection with the basic disease is discussed and this is put aside the essentially more frequent and more notorious secondary diseases of ulcerous colitis (arthritides, changes of skin, eyes and liver).
