It is well known that extra-intestinal complications are highly frequent in Crohn's disease. The incidence and charactaristic features of dermatologic lesions were examined in 163 patients with Crohn's disease in our hospital. The main complications were skin, joint, psycotic and stone manifestations. The incidence of dermatologic lesions was 36.2% in Crohn's disease. The main incidence of lesions was caused by erythema nodosum (4.9%), acne, atopic dermatitis, seborrhaeic eczema, stick finger etc. The most frequently observed type of dermatologic lesions were erythema nodosum. There was a high percentage of female patients who displayed the associated symptoms of colonic involvement and apthous stomatitis and fister ani. There was also a high incidence of stomatitis (29.4%) associated with small-intestinal involvement with Crohn's disease. Anal lesions were also common in Crohn's disease.The dermatologic manifestations of Crohn's disease were varied and associated with the study of the pathogenesis of Crohn's disease. |
