Cannon's disease or white sponge naevus is a relatively rare genetically determined skin disorder. It is inherited as an autosomal dominant trait that displays a high degree of penetrance and expressivity.Based on clinical data and histopathologic findings, the lesion was consistent with white sponge nevus. Because of benign nature of this lesion, no treatment is necessary and only biopsy and correct diagnosis is necessary to rule out other similar lesions. Six-month follow-up was recommended.
