There are many cases published in the literature of KS following treatment with anti-TNF-α including infliximab and golimumab: a case of a rheumatoid arthritis patient who developed KS lesion after infliximab treatment [112] and a patient with giant cell arteritis who developed KS in double-blind trial with anti-TNF-α [113], and a case of psoriatic arthritis patients who developed KS lesions during the course of treatment with infliximab [114]. This evidence concerns the gene TNF and Kaposi's sarcoma.
