Two white sponge nevus in a single family: case report

Introduction: White Sponge Nevus (WSN) is a leukokeratosis characterized by white lesions of the oral mucosa. These lesions are bilateral, thickened and raised compared to the adjacent mucosa. Their aspect are folded and spongy. It is a benign disorder with asymptomatics lesions which often appear during the childhood or the adolescence. The interest of this case report is that the diagnostic of WSN had been established directly, thanks to the presence of the patient's father. Observation: A twelve years old patient was examined in the unity of the oral mucosa pathology and oro-facials pain, of the oral surgery service of Bordeaux hospital (CHU de Bordeaux, France). He presented typical WSN lesions. His father was examined and presented the same lesions. Discussion: Diagnostic of WSN is mainly a clinical examination. There are a lot of differential diagnosis, and leukoplakia is the principal. In case of doubt about the diagnostic, a histological examination can be done. Nowadays, there is no consensus about the therapeutic. But the lesions are mainly asymptomatics, so any treatment has to be planed. Conclusion: An early WSN diagnosis avoids to patients a non adapted treatment and reassures young patients and their parents.
