Desquamative gingivitis: what's behind it? A case report.

Area of Science:

• Oral pathology
• Dermatology
• Dentistry

Background:

• Desquamative gingivitis (DG) is a clinical descriptor for erythematous, painful, and friable gingival tissues.
• DG can be a symptom of various mucocutaneous diseases, including oral lichen planus and vesiculobullous disorders.
• Distinguishing DG from plaque-induced gingivitis is crucial for accurate diagnosis and treatment.

Observation:

• This case highlights chronic DG co-occurring with oral lichen planus.
• The etiology of DG in this case was uncertain, potentially linked to plaque accumulation or as a manifestation of oral lichen planus.
• Clinical examination and biopsy confirmed features of both chronic DG and oral reticular lichen planus.

Findings:

• Biopsy results confirmed chronic desquamative gingivitis.
• Oral lichen planus, specifically the reticular subtype, was identified as a co-existing condition.
• The findings suggest a complex interplay between plaque and oral lichen planus in the presentation of chronic DG.

Implications:

• Highlights the importance of considering mucocutaneous diseases in cases of desquamative gingivitis.
• Emphasizes the need for dentists to recognize and differentiate rare conditions like DG associated with oral lichen planus.
• Suggests that biopsy and thorough examination are essential for diagnosing the underlying cause of chronic DG.
