Kaposi sarcoma after corticosteroid therapy for idiopathic thrombocytopenic purpura.

Kaposi sarcoma (KS) is a multifocal vascular neoplasm most commonly seen in association with human immunodeficiency virus infection. However, KS has also been reported in patients treated with immunosuppressive agents. However, it is very rare to find KS in association with idiopathic thrombocytopenic purpura (ITP). Here we describe a 58-year-old male patient suffering from ITP treated with corticosteroid therapy who developed KS and present a review of the literature.
