Eruptive Lichen Planus Associated With Chronic Hepatitis C Infection Presenting as a Diffuse, Pruritic Rash

Lichen planus has been associated with several precipitating factors, such as drugs, immunizations, and viral infections, including hepatitis C virus (HCV). Eruptive or disseminated lichen planus is a rare variation that most often presents as an acute, widespread exanthem that progresses rapidly and usually lasts for a shorter duration. This variation has not been well studied, and little is known about the etiologies and treatments of this rare form. Thus far, only a few cases of eruptive lichen planus have been reported to be associated with HCV infection. We report a case a 62-year-old woman who presented with a rapidly progressive, diffuse, pruritic rash of the trunk, upper extremities, and thighs that was determined to be eruptive lichen planus secondary to chronic HCV infection. The patient was treated with topical steroids and oral antihistamines, and her rash spontaneously resolved approximately six months after the initial presentation.
