Successful treatment of large area oral verrucous hyperplasia using diode laser ablation combined with photodynamic therapy: A case report.

Oral verrucous hyperplasia (OVH) refers to a whitish or pink elevated plaque or mass on the oral mucosa with either verrucous or papillary surface. Given its potential of malignant transformation, it is crucial to pursue aggressive treatment and close surveillance to the lesion. Herein, we present a case of a 43-year-old male patient with large area OVH on the left buccal mucosa who was successfully treated using diode laser ablation combined with 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT). After two sessions of treatment, the lesions regressed completely, and no recurrence was observed at the 18-month follow-up. Therefore, diode laser ablation combined with ALA-PDT may be an efficient and safe treatment modality for large area OVH.
