Abstract

We present the rare case of a 61-year-old man with Crohn’s disease who developed a cutaneous Kaposi’s sarcoma in the setting of long-term treatment with 6-mercaptopurine. Deciding on the best course of management provided a clinical challenge in an ‘evidence-light’ area. Relevant case reports and guidelines were reviewed. In general, the withdrawal of immunosuppressive therapy is advised; however, a multidisciplinary, case-by-case approach is also emphasised. The patient’s lesion was removed and, following collaborative discussion, immunosuppression was continued post resection. This is thought to be the first reported case involving a Kaposi’s sarcoma in inflammatory bowel disease where immune therapy was not subsequently discontinued.
