Porokeratosis plantaris discreta. A misnomer

Eighteen specimens from six patients with so-called porokeratosis plantaris discreta were studied with light and electron microscopy. The diagnosis was based on the classic descriptions by Taub and Steinberg. This study does not corroborate their findings. Based on this study and a review of recent literature, the use of the diagnostic term porokeratosis plantaris discreta should be discontinued.
