Summary

Oral erythroplakia (OE) is a rare, potentially malignant oral lesion with a high transformation rate. Further research is needed to understand its natural history, etiology, and optimal treatment.

Area of Science:

  • Oral Medicine
  • Oncology
  • Pathology

Background:

  • Oral erythroplakia (OE) is a rare potentially malignant lesion of the oral mucosa.
  • Terminology for mixed red and white lesions is complex and ill-defined.
  • Prevalence varies geographically, with a reported 0.2% in India.

Purpose of the Study:

  • To review the current understanding of oral erythroplakia.
  • To highlight knowledge gaps regarding its etiology, natural history, and treatment.
  • To emphasize the need for further research.

Main Methods:

  • Literature review of existing reports and studies on oral erythroplakia.
  • Analysis of epidemiological data, clinical presentation, and histopathological findings.
  • Discussion of etiological factors, including tobacco and alcohol consumption.

Main Results:

  • OE predominantly affects the middle-aged and elderly, with a near equal male:female ratio.
  • Commonly affected sites include the soft palate, floor of mouth, and buccal mucosa.
  • Histopathology reveals a high rate of invasive carcinoma (51%), carcinoma in situ (40%), and dysplasia (9%).

Conclusions:

  • OE has the highest transformation rates among precancerous oral lesions.
  • Surgical excision is the current treatment of choice, but recurrence rates are high.
  • Significant knowledge gaps exist regarding OE's natural history, role of infections, and optimal management, necessitating further studies.
