Cutaneous Extraintestinal Manifestations of Ulcerative Colitis / 胃肠病学

ABSTRACT

The incidence of ulcerative colitis (UC) is increasing in recent years, and its pathogenesis is not completely clear. The extraintestinal manifestations (EIM) of UC are diverse and can involve multiple organ systems such as bone and joint, skin, liver and gallbladder, eye, etc. The incidence of one EIM increases the risk of development of other EIM. Cutaneous manifestations are important EIM of UC, and are usually classified into reactive, immunity-associated, malnutrition and treatment-induced manifestations. This article reviewed the clinical symptoms, diagnosis and treatment of cutaneous extraintestinal manifestations of UC.
