i have heard of it actually being a sign of cirrhosis when accompanied with other symptoms & tests. It usually is on the base of your palms (fat part of hands).
Before you panic there are many things that can cause red palms, i.e. hormones, medication, etc.
If your doctor is basing HCV on this alone find another doctor quick !
Google 'Palmar Erythema' for more information. Also know as Red Palms.
