Summary

A novel oral mucosal condition causes asymptomatic peeling of gray-white tissues. Histopathology reveals an intraepithelial cleft, distinct from known oral diseases.

Area of Science:

  • Oral pathology
  • Dermatology
  • Histopathology

Background:

  • Describes a rare oral mucosal condition characterized by asymptomatic gray-white tissue sloughing.
  • Resembles leukoedema and chemically irritated mucosa but lacks definitive causes.

Observation:

  • Presents four cases of a unique oral mucosal peeling phenomenon.
  • Affected tissues were asymptomatic, gray-white, and sloughed, revealing normal underlying tissue.

Findings:

  • Histopathological examination revealed an intraepithelial cleft parallel to the epithelial surface.
  • Intracellular edema was observed in adjacent cells, similar to leukoedema.
  • Ruled out acantholysis, inflammation, and differential diagnoses like pemphigus vulgaris, mucosal pemphigoid, lichen planus, candidiasis, and mucosal biting.

Implications:

  • This condition represents a distinct clinicopathological entity in oral mucosal diseases.
  • Further research is needed to identify the etiology of this unusual oral mucosal peeling.
  • Highlights the importance of detailed histopathological analysis for diagnosing rare oral lesions.
