Figure 2. In this high-power image we can observe infiltrate consisting of atypical spindled endothelial cells forming vascular channels intersecting between collagen bundles. Promontory sign (normal vessel enveloped in atypical vascular space) is present in the black box. This characteristic is not specific for KS and can also be seen in other vascular neoplasms such as angiosarcoma.
