White sponge naevus: recognition of this disorder is important to differentiate from premalignant oral lesions


S Seremet, FS Afsar, H Duran, G Yilmaz, M Ermete


White sponge naevus (WSN) is a rarely seen autosomal-dominant disease. It is characterised by white plaques seen on the buccal, gingival and oral mucosae. It has a prevalence of less than 1/200,000. This entity is also known as Cannon's disease, hereditary leucokeratosis of mucosa, white gingivostomatitis or exfoliative leucoedema. Given that WSN is a rare disease, we present a 16-year-old boy with WSN.
