Kaposi sarcoma development following microscopic polyangiitis treatment

Abstract

Kaposi sarcoma (KS) is a rare condition mostly seen in immunosuppressed patients due to a syndrome or organ transplantation. However, few cases have been reported in patients with rheumatologic diseases treated with long-term corticosteroid and cyclophosphamide. We present a case in which the subject developed KS following a course of immunosuppressive therapy for their systemic vasculitides.
