Rituximab seems a promising therapeutic option in granulomatosis with polyangiitis with intestinal perforation: a case report and literature review.

Granulomatosis with polyangiitis (Wegener's) (GPA) is a chronic disease of unknown aetiology that leads to necrotising vasculitis in small and medium-sized vessels characterised by respiratory system and kidney involvement. Intestinal involvement is rare and perforation is even rarer in GPA. In this study, we are presenting a literature review of related cases, and a 29-year-old man referred from the emergency department with a multiple distal ileal perforation that was diagnosed with GPA, and successfully treated with rituximab.
