White sponge nevus of the vulva
Summary
White sponge nevus, a hereditary leukokeratosis, typically affects the mouth. This report details an extremely rare case of exclusively extraoral vulvar white sponge nevus in an 18-year-old patient.
Area of Science:
- Dermatology
- Genetics
- Gynecology
Background:
- White sponge nevus (WSN) is an inherited condition characterized by leukokeratosis, primarily affecting oral mucosa.
- While typically oral, WSN can manifest in other mucocutaneous areas, presenting diagnostic and therapeutic challenges.
Observation:
- A case report of an 18-year-old female patient presenting with a white sponge nevus.
- The WSN was uniquely located primarily and exclusively on the vulva, with no oral or perianal involvement.
Findings:
- This case highlights an exceptionally rare extraoral presentation of white sponge nevus.
- The diagnosis required careful differential consideration due to the unusual location.
Implications:
- This case expands the known clinical spectrum of white sponge nevus.
- It underscores the importance of considering WSN in the differential diagnosis of vulvar leukokeratotic lesions.
