==General==
*Benign non-neoplastic lesion - a vessel that has thrombosed and recanalized.
*Histomorphologically may be confused with low-grade [[angiosarcoma]] or other soft tissue sarcomas.<ref name=pmid15865098/>

==Microscopic==
Features:
*Well-circumscribed - '''key (low power) feature'''.
*Abundant small vascular channels with benign endothelium.
*+/-Papillary formation with a fibrotic core covered by benign endothelium.<ref>URL: [http://path.upmc.edu/cases/case544.html http://path.upmc.edu/cases/case544.html]. Accessed on: 25 January 2012.</ref>
