Abstract
Wegener's granulomatosis (WG) is a disease characterized by a granulomatous necrotizing vasculitis of small vessels. Although any organ systems can be involved, gastrointestinal involvement in WG is notably uncommon. We present a case of 67-year-old man who was admitted with abdominal pain and diarrhea lasting for 3 weeks. Colonoscopy and abdominal CT scan revealed vasculitis and multiple mesenteric lymphadenopathy. Jejunum and mesenteric lymph nodes biopsies confirmed limited form of WG. The present case indicates that WG might in-volve only gastrointestinal tract and the histological confirmation is important for diagnosis.
