a. telangiectasia.

c. petechiae.
d. purpura.
B
Spider angiomas are dilated arterioles. A network of dilated capillaries radiate from the center arteriole, outward like a spider's legs. Spider angiomas are often associated with high estrogen levels, as occur in pregnancy. Blanching over the center is followed by a rapid return of redness from the center outward. Telangiectasis refill erratically. Petechiae and purpura do not blanch.
