Cutaneous involvement with Crohn's disease at a site separated from the gastrointestinal tract by normal skin is termed metastatic Crohn's disease. Such a complication is extremely rare and previous reports have emphasised the flexural distribution of the ulcerated lesions. We report a patient who developed Crohn's disease involving the skin of the thigh and forearm several months after a panproctocolectomy for colorectal Crohn's disease.
克罗恩病累及皮肤，病变部位与胃肠道之间隔着正常皮肤，这种情况被称为转移性克罗恩病。这种并发症极为罕见，既往报告强调溃疡性病变好发于皮肤褶皱处。我们报告一例患者，在因结直肠克罗恩病行全直肠结肠切除术后数月，出现累及大腿和前臂皮肤的克罗恩病。
