Acquired blaschkolinear psoriasis is a rare entity. It is commonly confused clinically and histopathologically with inflammatory linear verrucous epidermal nevus and other acquired blaschkolinear dermatoses. We describe a case of psoriasis with a striking band-like and linear distribution in a 21 year old woman. The history of asymptomatic acquired erythematous scaly lesions, the peculiar distribution, the histopathology and the favourable response to anti-psoriatic treatment confirmed the diagnosis.
