The extraintestinal disorders in Crohn's disease are common and they are part of the diagnostic criteria of the disease. They are varied and can affect the joints, skin, and eyes. So we try to identify their epidemiological aspects and clinical, evolving through a series of 222 cases of Crohn's disease. In our series, 37.83% of patients experienced at least one extraintestinal manifestation. The mean age was 35.25 years, with the sex-ratio of 0.75. Joint damage was observed in 33.33% of patients (74 cases), with 28 cases of axial damage and 46 cases of peripheral damage including 9 cases of arthritis. The dermatological disease was observed in 9.45% of patients (22 cases), dominated by oral aphthous ulceration (9 cases), erythema nodosum (5 cases), and pyoderma gangrenosum (4 cases). Ocular involvement was observed in 5.40% of patients (12 cases), including two cases of anterior uveitis, six cases of dry eye syndrome, three cases of redness, and one case of episcleritis. The extraintestinal manifestations in Crohn's disease are fairly common and variable, occurring both in pushing period of quiescence of the disease, as they can precede digestive symptoms. Joint manifestations are the most common, followed by dermatological manifestations.
