[Erosive arthropathies in Crohn disease. Apropos of 3 cases].

Three unusual cases of destructive joint lesions in patients with Crohn's disease are reported. One patient with chronic enteropathic polyarthritis developed erosions of the wrists. The other two patients had spondyloarthropathic disease; erosions developed in the right hip in one and in the hips, knees and tibiotarsal joints in the other. The few similar cases reported in the literature are reviewed.
