Summary
Proliferative verrucous leukoplakia (PVL), a rare oral condition with high cancer risk, has now been observed in the skin. This case report highlights a novel presentation of PVL beyond its typical oral location.
Area of Science:
- Dermatology
- Oral Pathology
- Oncology
Background:
- Proliferative verrucous leukoplakia (PVL) is a recognized oral potentially malignant disorder.
- PVL is histologically characterized by a high risk of malignant transformation into verrucous squamous cell carcinoma.
- Previous literature has exclusively documented PVL within the oral cavity.
Observation:
- This report details an unprecedented case of PVL occurring on the skin (cutaneous PVL).
- The clinical and histological presentation of this cutaneous PVL is described.
- This finding expands the known anatomical distribution of PVL.
Findings:
- The study confirms the existence of cutaneous PVL, a previously unreported entity.
- Histopathological analysis revealed features consistent with PVL in a skin lesion.
- This challenges the established understanding of PVL's typical localization.
Implications:
- The findings suggest that PVL may not be exclusively an oral condition.
- This broadens the differential diagnosis for verrucous skin lesions.
- Further research is warranted to understand the pathogenesis and behavior of cutaneous PVL.
