Lichen planus pemphigoides after COVID‐19 infection.

This article discusses a rare autoimmune bullous disease called lichen planus pemphigoides (LPP) that developed in a 50-year-old Caucasian male two weeks after a COVID-19 infection. LPP is characterized by lichenoid and/or bullous skin lesions and the presence of IgG autoantibodies against certain proteins in the skin and mucous membranes. The patient in this case study exhibited the clinical, histopathological, and serological criteria for LPP. The article also mentions the overlap between LPP, bullous lichen planus, and bullous pemphigoid, and highlights the importance of detecting autoantibodies to support the diagnosis. This is the first reported case of LPP after a COVID-19 infection. [Extracted from the article]
