Photomicrographs of anti-CD68 and anti-CD169 stained sections of selected tissues The two frozen skin biopsies show a similar histopathological picture of nodular stage Kaposi's sarcoma. Left panels (A/D): HE staining; middle panels (B/E): αCD68 staining; Right panels (C/F): αCD169 staining. Throughout the dermis, vascular proliferations are found surrounded by irregular, rather dense areas of atypical spindle cell proliferations. Both lesions contain sparse inflammatory cell infiltrates, mainly consisting of CD68+ macrophages.
