Nevoid psoriasis: an uncommon Blaschkolinear Dermatosis.
J Pak Assoc Derma Jan ;14(3):156-9.

Nevoid or linear psoriasis is an uncommon form of psoriasis characterized by the linear or zosteriform distribution of the psoriatic lesions. It usually follows the lines of Blaschko with unilateral involvement. It is commonly confused clinically and histopathologically with verrucous epidermal nevus. We report a young male, who had linear psoriasis in a unilateral distribution over his shoulder and arm. He was diagnosed on clinical as well as histological ground and was managed on the lines of psoriasis.
