title: A radiologic sign of epidermolytic hyperkeratosis.
abstract: The radiologic finding of innumerable fine ridges in the outer soft tissues of a patient with severe generalized epidermolytic hyperkeratosis is presented as a sign of the disease. The radiodensity results from the density of keratin and low water content in the scales of epidermolytic hyperkeratosis.
