BACKGROUND A 6-year-old girl with a symmetric linear eruption on both of her legs, clinically and histologically resembling inflammatory linear verrucous epidermal nevus (ILVEN) or linear psoriasis (LP), with concomitant psoriasis of the guttata type and a positive family history of psoriasis is presented. The questions as to whether LP actually exists and ILVEN represents a distinct entity are...

Porokeratotic eccrine ostial and dermal duct nevus (PEODDN) is known as an uncommon disorder of keratinization in which acrosyringium is involved; however, its causes have yet remained unknown. It is presented clinically by discrete keratotic papules on distal extremities arranged in a linear pattern along Blaschko lines. Histopathologically, it is characterized by cornoid lamella, which is alm...

We describe an unusual case of late-onset unilateral segmental DD that follows the lines of Blaschko. Our patient did not exhibit other classic findings of DD. Our case and review of the literature suggest that lesions previous...
