[Extra-cutaneous systemic manifestations in generalized pustular psoriasis].

Generalized pustular psoriasis of the von Zumbusch type is a severe form of psoriasis characterized by disseminated pustular skin lesions with high fever and hyperleukocytosis. We report a 32-year-old woman who presented a generalized pustular psoriasis with extra-cutaneous manifestations of the disease that included pulmonary involvement, aseptic arthritis, jaundice, and liver abnormalities. The extra-cutaneous manifestations of generalized pustular psoriasis should be known to physicians caring for patients with psoriasis in order to avoid diagnostic delay.
