ABSTRACT
Over the last decade, the concept of psoriasis has evolved from being considered a pure cutaneous disease to a chronic inflammatory skin disease with a risk of systemic comorbidities. A wide constellation of comorbid conditions virtually affecting every system has been reported. In this chapter, we review the comorbidities affecting the gastrointestinal system, the liver, the lung, and finally, the association of psoriasis with neoplastic disorders.
