    Area of Science:

    • Dermatology
    • Oral Medicine
    • Oncology

    Background:

    • Chronic snuff use can lead to precancerous oral lesions like keratosis and ulcerations.
    • These lesions represent a significant risk for oral cancer development.

    Purpose of the Study:

    • To evaluate the efficacy of topical vitamin A acid in treating snuff-induced oral keratosis and associated ulcerations.
    • To assess the healing and regression potential of these precancerous lesions with vitamin A acid therapy.

    Main Methods:

    • Patients with chronic snuff-induced keratosis and mucosal ulcerations were treated with topical vitamin A acid.
    • Clinical observation and assessment of lesion response were conducted during treatment.

    Main Results:

  • Topical vitamin A acid induced a local inflammatory response initially, followed by beneficial effects.
  • Complete healing and restoration of normal mucosa occurred in one patient within five weeks.
  • Superficial ulcerations healed and leukoplakic lesions regressed in size in four patients.

    • Conclusions:

    • Topical vitamin A acid demonstrates a beneficial effect in promoting healing and involution of precancerous snuff-induced oral lesions.
    • Vitamin A acid therapy is a promising approach for managing snuff-induced keratosis and associated mucosal damage.
