title: Avoiding "Rash" Conclusions: Challenge of IgA Vasculitis in Adults.
abstract: IgA vasculitis is primarily a pediatric disease that is rarely encountered in adults. With adults, gastrointestinal manifestations are quite common, yet are nonspecific and may overlap with other diseases, particularly Crohn's disease, which can make the diagnosis a challenging task. Treatment is controversial given the disease course is usually self-limited with few serious complications. We present a case of IgA vasculitis in an adult patient with limited extraintestinal findings illustrating the complexity of arriving at the correct diagnosis.
