Answer to Medical Quiz
The answer to yesterday's image challenge is #1. spider hemangioma.
Spider angiomas can be seen in healthy children and pregnant women. In such cases, angiomas are few in number and resolve with time or a normalization of estrogen levels. Numerous spider angiomas are more common in patients with chronic liver disease and consist of a central arteriole from which numerous small venules radiate, resembling a spider's legs. Possible mechanisms of formation include arteriolar vasodilatation, neovascularization from angiogenic factors such as vascular endothelial growth factor, direct effects of alcohol, and estrogen excess due to inadequate hepatic metabolism.
