White spongy nevus: A nonhereditary presentation

Abstract

White spongy nevus (WSN) is a rare hereditary dyskeratotic hyperplasia of the mucous membranes. It is an autosomal dominant disorder with variable penetrance. A few cases of WSN occur due to de novo mutations. We report a case of WSN in a 12-year-old female child, with none of her family members having similar lesions.
