Abstract:
In the course of inflammatory bowel disease (IBD) a number of extraintestinal manifestations are known to occur, being the dermatological ones often associated to both ulcerative colitis and Crohn's disease. Pyoderma gangrenosum and erythema nodosum are the most frequent, but there are other skin manifestations less frequently reported such as leukocytoclastic vasculitis. We present a case, in which Crohn's disease and leukocytoclastic vasculitis were simultaneously diagnosed, and corticoids treatment achieved complete remission of the both cutaneous and gastrointestinal manifestations.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
