Polyarteritis nodosa is a systemic necrotizing vasculitis that affects mainly small and medium-sized arteries that involve multiple organs. In addition to the systemic involvement of classical vasculitis, localized vasculitis involves blood vessels within a confined vascular distribution or single organ without clinical evidence of generalized inflammation. Localized vasculitis of the gastrointestinal tract is a rare entity. In particular, a limited involvement of the small bowel is an unusual manifestation of polyarteritis nodosa. In this report, we describe a case of biopsy-proven polyarteritis nodosa presenting as small bowel bleeding without other systemic manifestations. (Korean J Gastrointest Endosc 2010;41:113-117)
