The condition marked by a red arrow in the picture above represents leukoplakia.
Oral leukoplakia
- It is a white patch or plaque that cannot be rubbed off, cannot be characterized clinically or histologically as any other condition.
- Causative factors: tobacco use, alcohol consumption, chronic irritation, chronic cheek biting; ill-fitting dentures, candidiasis, vitamin deficiency, and possibly a virus.
- Oral Leukoplakia is considered to be potentially malignant, with a transformation rate from 0.6 to 20%.
- Oral Leukoplakia is classified into two main types: homogeneous type which appears as a flat white lesion and non-homogeneous type which includes speckled, nodular and verrucous leukoplakia. The speckled type is a white and red lesion, with a predominantly white surface.
- Proliferative verrucous leukoplakia is a subtype of verrucous leukoplakia characterized by an aggressive evolution, a multifocal appearance, resistance to treatment, a higher degree of recurrence and a high rate of malignant transformation
- In all cases, the relative risk of malignant potential is determined by the presence of epithelial dysplasia upon histological examination.
- Surgical excision of oral leukoplakia (OL) may be considered.
- Frequent clinical observation accompanied by photographic records is recommended.
