Abstract:
Kaposi's sarcoma (KS) is an unusual vascular tumor associated with human herpesvirus-8 (HHV-8) infection, which is common in immunosuppressors. Although extremely rare, iatrogenic (drug-related) KS can occur in human immunodeficiency virus (HIV)-negative patients under immunosuppressive therapy. We report a 64-year-old male diagnosed with ulcerative colitis for 1 year. He was treated with methylprednisolone because of an acute severe disease flare. He presented with several popular violet lesions on the body 4 months after steroid therapy. Histological examination of skin biopsies showed Kaposi's sarcoma associated with HHV-8. The skin lesions regressed after steroid withdrawal and chemotherapy. Two key words "Kaposi's sarcoma" and "inflammatory bowel disease" were searched in Wanfang data and CNKI, but no relevant articles were found. Thirty-eight articles in English were retrieved on PubMed with the key words of ("ulcerative colitis" OR "Crohn's disease" OR "inflammatory bowel disease") AND (Kaposi sarcoma). Twenty-five cases of Kaposi's sarcoma related to inflammatory bowel disease (IBD) were reported. Including this case, the majority of 26 Kaposi's sarcoma related IBD patients were male (80.8%, 21/26). The average age was (51.1 ± 16.4) years. Twenty cases were ulcerative colitis and 6 were Crohn's disease. All the patients received immunomodulatory therapy, including glucocorticoid, azathioprine/mercaptopurine, methotrexate, cyclosporin and anti tumor necrosis factor α antibody. Thirteen cases were positive for HHV-8. There were 18 cases involving the distal ileum and colorectum only, 3 cases involving skin only, and 5 cases involving both skin and colorectum at the same time. Overall, the prognosis was good. Three patients only stopped immunosuppressive therapy, 1 received radiotherapy, 1 received chemotherapy, and 20 received surgery. Kaposi's sarcoma could be seen in IBD patients with immunomodulatory therapy. It is very important to distinguish from the skin lesions related to IBD or drug treatment. The adverse reactions of immunomodulatory therapy should not be ignored. In addition, attention should be paid to the cooperation of multi-disciplinary team, which can diagnose and treat rare cases earlier and more accurately.
