title: [Idiopathic sclerosing mesenteritis. Case report and differential diagnosis of a rare disease picture].
abstract: We report the case of a 78-year-old woman with the endoscopic tentative diagnosis of a malignant tumor of the colon ascendens (biopsy without malignancy) that was removed by right hemicolectomy. Extensive mesenteric infiltration and colonic obstruction seemed to confirm this diagnosis. Surprisingly histology revealed invasion by sclerosing mesenteritis. The differential diagnoses include inflammatory pseudotumor, tumor-like fibromatosis at traumatized sites, idiopathic retroperitoneal fibromatosis, sclerosing malignant lymphoma, liposarcoma and drug-induced sclerosing mesenteritis, as well as mesenteric infiltration and metastases. Though preoperative diagnosis is not possible in most cases, the intraoperative macroscopic appearance and the histopathologic picture are conclusive.
