Seven cases of a solitary tumor, with the histopathologic feature of granular degeneration, were identified as isolated epidermolytic acanthoma. Clinically the lesion is not diagnostic, but resembles a wart. It is apparently not heritable, although it shows the same microscopic features as the dominantly inherited dermatoses recently termed epidermolytic hyperkeratosis.
