[Inflammatory bowel disease and psoriasis about two cases]

Cutaneous manifestations of inflammatory bowel disease are relatively common. An association with psoriasis has been rarely observed. Case reports: We report the cases of two patients, 60 and 48 years old, suffering respectively from ulcerative colitis and Crohn's disease. The first patient had a 6 years history of plaque psoriasis. In the second case, skin lesions appeard simultaneously to the flare of inflammatory bowel disease. The association of inflammatory bowel disease and psoriasis may be explained by the similarity of genetic and immunological factors in both disorders
