In brief: Ichthyosis
Ichthyosis (fish scale disease) is an inherited condition characterized by dry scaly skin as a result in defective skin barrier function.
The most common subtype is ichthyosis vulgaris, which is pigmentless.The rare subtype, epidermolytic hyperkeratosis, is characterized by retained thickened scales in skin folds, giving the appearance of "dirty skin" even though no pigment is actually deposited.
