Question: Name the physical exam finding in the image below!
Answer: This is livedo reticularis. This can be localized or more widespread, and is patchy, reticulated and appears like a vascular network. The colour is red-blue or violaceous and can occur as a result of medium-vessel vasculitis, vasospasm, thrombosis, hypercoagulable disorders, or in the setting of an embolic cause. The article that the picture is from cites livedo reticularis in the setting of infective endocarditis.
