Abstract
Annular atrophic lichen planus (AALP) is a chronic subtype of lichen planus that classically does not respond to treatment with topical steroids. An inflammatory reaction in the dermal infiltrate may play a role in the development of AALP, but the exact pathogenesis remains unclear. We present the case of a 54-year-old-female with lesions on her trunk and extremities that developed following vaccination. Her failed treatment response warranted further workup for AALP, which was confirmed around 1 year after initiation. Although vaccine-induced lichen planus is not common, it has been reported in various cases. We present a rare case of AALP following vaccination and then provide an in-depth discussion of factors associated with the condition and current treatment response.
