Abstract
Die Porokeratosis ptychotropica stellt eine sehr seltene Unterform der Porokeratosen, einer heterogenen Gruppe erblicher Verhornungsstörungen, dar. Es kommt zu verrukösen, großflächigen, hyperkeratotischen Plaques in der Perigenital‑, Gluteal- und Inguinalregion. Histologisch weisen die Porokeratosen eine pathognomonische Veränderung auf, die sog. kornoide Lamelle. Die Behandlungsergebnisse sind meist enttäuschend und mit hohen Rezidivraten verbunden.
