[Crohn's disease with several intestinal foci ("skip lesions")].

A 35-year-old man underwent a resection of part of the ileum due to six "skip lesions" in Crohn's disease. At reoperation four years later, in addition to a typical terminal ileitis, two stenosing lesions were found at the ileal-jejunal junction. In connection with this rare observation, a report is made on multiple lesions and the diffuse type of Crohn's disease, both of which must be included in the therapeutic concept. "Adequate" resections including all segmental lesions are demanded, different resections in additional distant lesions, and conservative medical treatment in the widespread diffuse type of the disease.
