Delayed-Type Hypersensitivity Reaction to Red Tattoo Ink Triggered by Ledipasvir/Sofosbuvir for Hepatitis C: A Case Report

Abstract: Tattoos have become increasingly popular worldwide making adverse effects from tattoos a growing concern. In our report, we present a 51-year-old man who developed an unusual allergic reaction to the red ink portions of his tattoos that coincided with the initiation of ledipasvir/sofosbuvir treatment for his hepatitis C. Clinical and histological features were consistent with a delayed-type hypersensitivity reaction to red ink.

“…Drug-induced tattoo reactions are not very frequent AEs, although tattoo-associated skin reactions have been reported during immune restoration syndrome with highly active antiretroviral therapy for human immunodeficiency virus [16], therapy for hepatitis C [17,18] and tumor necrosis factor α inhibitors [19]. Immune checkpoint inhibitors are also associated with various dermatologic manifestations, including sarcoidosis and granulomatous reactions to tattoos [8,20].…”

“…As the allergen is usually unidentified, the exact pathomechanism of chronic allergic reaction to red ink tattoo is also not fully explained. Presumably, the mechanism is that metabolism of the ink or reaction of an ink antigen with a carrier protein in the dermis over a long time triggers a delayed hypersensitivity reaction [ 17 , 18 ]. In line with the presumed pathophysiology, chronic allergic tattoo reactions occur months or years following body art completion.…”
