Inclusion criteria: Clinically: 1. The presence of bilateral lesions with a certain degree of symmetry; 2. The presence of a lace-like reticulation (reticular type) composed of gray-white lines slightly above the mucosal surface; 3. It can be manifested as erosive, atrophic, bullous and plaque-type lesions, but there must be a reticular type in other parts of the oral mucosa. Pathologically: 1. The presence of a well-defined, band-like zone of cellular infiltration that is confined to the superficial part of the connective tissue, consisting mainly of lymphocytes; 2.
