White sponge nevus with epidermolytic changes.
A 42-year-old man with extensive white spongy lesions of the oral mucosa from childhood is reported. Histologic examination of two punch biopsies revealed many foci of epidermolytic hyperkeratosis. Similar lesions were present in one of his two brothers but he refused the biopsy. The problems of differential diagnosis are discussed.
