Oral squamous-cell carcinoma within a white-sponge nevus
The Journal of Dermatologic Surgery and Oncology
|June 1, 1978
Summary
A patient initially diagnosed with benign white sponge nevus developed oral squamous cell carcinoma. Prednisone therapy for asthma may have suppressed immune surveillance, allowing cancer to develop.
Area of Science:
- Oral pathology
- Immunology
- Oncology
Background:
- White sponge nevus is a rare, benign, hereditary disorder of the oral mucosa.
- Oral leukoplakia can represent a precancerous lesion or oral cancer.
Observation:
- A 59-year-old woman presented with bilateral leukoplakia on the tongue.
- Initial biopsy diagnosed white sponge nevus.
- A suspicious area on the right side revealed squamous cell carcinoma upon a second biopsy two years later.
Findings:
- The development of squamous cell carcinoma in a patient with a history of white sponge nevus.
- Speculation that long-term prednisone therapy for steroid-dependent asthma may have compromised immunologic surveillance.
- Potential link between immunosuppression and malignant transformation of a benign condition.
Implications:
- Highlights the importance of vigilant monitoring for malignant transformation in patients with oral white sponge nevus.
- Suggests a potential role for iatrogenic immunosuppression in the development of oral cancer.
- Underscores the need for further research into the interplay between immune status and oral precancerous lesions.
