Cryotherapy Treatment of Cutaneous Kaposi Sarcoma in a Patient With B-Cell Chronic Lymphocytic Leukemia: A Case Report and Short Review of the Literature

Introduction. Kaposi sarcoma (KS) is a low-grade mesenchymal tumor involving the blood and the lymphatic vessels that primarily effaces the skin and is mediated by human herpesvirus-8 (HHV-8) in more than 90% of patients. There are 4 distinct types of KS. Compared with the classic and AIDS-related variants, chronic lymphocytic leukemia (CLL) associated with KS is a relatively rare clinical condition; thus, only a few cases have been reported. Case Report. This report presents a case study of an 87-year-old patient with B-cell CLL and cutaneous KS managed with cryotherapy, along with a short review of the literature. Conclusions. Considering that the method is relatively simple and with few adverse effects, cryotherapy may represent a simple and safe treatment method for cutaneous KS. However, more studies should be conducted to further evaluate the effectiveness of cryotherapy as a promising treatment for cutaneous KS.
