A rare skin disease characterized by a hamartomatous epidermal lesion presenting as a linear array of verrucous, hyperkeratotic papules that often coalesce into plaques and are formed along the lines of Blaschko. The condition is associated with involvement of other organ systems, mainly brain, eye, and skeletal system. It is the result of mosaic post-zygotic mutations and most commonly presents at birth, but may occur anytime during childhood, rarely also in adulthood.

PENS syndrome is a rare, genetic, neurocutaneous syndrome characterized by the presence of randomly distributed, small, white to yellowish, multiple, rounded or irregular polycyclically-shaped, epidermal keratotic papules and plaques of gem-like appearance with a rough surface, typically located on the trunk and proximal limbs, associated with variable neurological abnormalities, including psychomotor delay, epilepsy, speech and language impairment and attention deficit-hyperactivity disorder.
