Background: Lichen planus (LP) pemphigoides (LPP) is a very rare autoimmune bullous disorder, that is, exceptional in children.

Case Report: We report a case of LP pemphigoides with severe cutaneous and mucosal involvement in an 8-year-old girl who consulted for multiple vesicular and bullous lesions associated with shiny erythematous-purple plaques. The eruption occurred 2 months after vaccination against hepatitis A virus.
