Summary
This case study presents a non-familial white sponge nevus (WSN) in an 8-year-old girl. WSN shares keratin expression similarities with the epithelia of the hard palate and tongue.
Area of Science:
- Oral pathology
- Dermatology
- Genetics
Background:
- White sponge nevus (WSN) is a rare, benign, hereditary intraepithelial disorder of the oral mucosa.
- Non-familial cases, though rare, necessitate thorough differential diagnosis.
Observation:
- An 8-year-old girl presented with a non-familial case of white sponge nevus.
- Clinical, anamnestic, and histopathological data were analyzed.
Findings:
- Differential diagnosis for white sponge nevus was discussed.
- Keratin expression in WSN was found to resemble that of the hard palate and tongue epithelia.
Implications:
- Understanding keratin expression aids in diagnosing white sponge nevus.
- This case highlights the importance of considering non-familial WSN and its differential diagnoses.
