Cutaneous kaposi sarcoma during treatment with steroids and rituximab for pemphigus foliaceus
Pemphigus foliaceus (PF) is an autoimmune disease with bullous manifestations on the surface of the skin that requires long-term administration of immunosuppressive medications. Kaposi’s sarcoma (KS) is one of the diseases that manifest in people with innate or acquired immune systems deficiency with the direct involvement of HHV-8 and causes polypoid skin lesions. This study was conducted on a 78-year-old man with a history of PF treated with immunosuppressive drugs. In this patient, a secondary polypoid lesion had been created around the anus and the results of pathological tests had confirmed the KS.
