Reactions 1704, p298 - 2 Jun 2018 Lichen planus: case report A 53-year-old woman developed lichen planus following treatment with peginterferon-α-2b for chronic hepatitis B infection. The woman, who had chronic hepatitis B infection, started receiving treatment with SC peginterferon-α-2b 1.5 µg/kg weekly for 48 weeks. At 21 weeks of interferon therapy, she developed burning, sharp sensation in the mouth that worsened with cold food. She completed a total of 48 weeks of peginterferon-α-2b therapy. Examination revealed atrophic and ulcerated erythematous plaques on the buccal mucosal surface with white striae. Incisional biopsy showed a lichenoid lymphoplasmacytic infiltrate in the subepithelial stroma. Overlying squamous epithelium revealed sawtoothed rete ridges, neutrophilic and lymphocytic exocytosis, occasional apoptotic keratinocytes, intercellular oedema and parakeratosis. Based on these findings, she was diagnosed with oral lichen planus. The woman was treated with triamcinolone dental paste. She showed an improvement in pain and burning discomfort over the next 4 weeks, with decrease in the ulcer. Author comment: "[Lichen planus] has also been reported to develop or worsen with interferon therapy, largely in the context of hepatitis C."
