Occasionally, people with chronic hepatitis C develop a skin condition called
lichen planus. It is a grouping of small, itchy, irregular, flat-topped
reddened bumps. The bumps often have a network of very fine gray lines on
their tops. The bumps show up most often on the wrists, shins, lower
back, or genitals.
Lichen planus also frequently occurs in the mouth, where it looks like a white, net-like plaque. It sometimes shows up as mouth ulcers and can be treated with a steroid mouth rinse called Dexamethasone Elixir or Nystatin tablets.
