[Leukoplakia-like epidermal nevus of the mouth mucosa. Case report].

We report on a nevus of the oral mucosa, which became present in the age of 30 of a male patient. By microscopic examination we did not find any vacuolation of the spinous layer of the epithelium. So this nevus has been considered quite different from the typical white sponge nevus, and we prefer to name it leucoplakial nevus of the oral mucosa.
