Erosive lichen planus clinically mimics which of the following conditions:
Show answer Hide answer
Answer: B. Desquamative gingivitis
Explanation
Erosive lichen planus clinically presents as painful desquamative gingivitis, mimicking vesiculobullous mucosal diseases. Destruction of the basal cell layer causes bright red erosions across the attached gingival tissues. This clinical presentation shares striking similarities with other vesiculobullous conditions affecting oral mucosa. Lichen planus is a chronic inflammatory mucocutaneous disorder presenting in reticular, plaque-like, or erosive forms. Desquamative gingivitis describes a clinical gingival appearance rather than a specific definitive histopathological diagnosis. Biopsy and direct immunofluorescence help differentiate lichen planus from autoimmune blistering mucocutaneous diseases.
Patients with erosive gingival lesions experience significant pain and bleeding during routine toothbrushing. Topical corticosteroid therapies are frequently prescribed to manage painful erosive mucosal disease symptoms. Accurate differential diagnosis prevents mistaking autoimmune blistering diseases for localized inflammatory gingivitis. Monilial gingivitis refers to candidal infections presenting as removable white pseudomembranous plaques. Herpetic gingivitis presents with clustered vesicular eruptions that rapidly rupture into painful ulcers. Acute ulcerative gingivitis is characterized by painful punched-out interdental papillae caused by specific bacteria.
