IL-23 Expression in Stewart-Treves Syndrome: Two Case Reports and Immunohistochemical Investigation

Abstract

Stewart-Treves syndrome (STS) is a rare cutaneous lymphangiosarcoma developing from chronic lymph edema as a consequence of radical mastectomy or surgical invasion of the groin for the treatment of cervical or penile cancer. Previous reports suggested possible mechanisms in the development of lymphangiosarcoma that correlate with the immunological background of STS patients. In this report, we described two cases of STS developing in patients who underwent radical dissection for cervical cancer, we employed immunohistochemical staining of IL-23 and IL-17.
