Abstract
Enterocolic lymphocytic phlebitis is a rare cause of segmental ischemic enterocolitis. This artery-sparing transmural vasculitis is classically a circumferential phlebitis with perivenular lymphocyte cuffing and thrombi in the absence of systemic manifestations. Myointimal hyperplasia may represent a chronic phase of enterocolic lymphocytic phlebitis. Subclinical or early stage enterocolic lymphocytic phlebitis is not well delineated. We analyzed 600 submucosal and subserosal veins from both ischemic and intact bowel segments to discern if vascular morphology varied between sites. Crescentic and circumferential lymphocytic phlebitis is more common in viable bowel than in the ischemic segment. A nonsignificant trend was found for increased crescentic morphology between intact bowel remote from the ischemic focus compared with that adjacent to the ischemic focus. Hallmarks of ischemic bowel are necrotizing phlebitis and thrombi formation. Thrombophlebitis morphology is distinctly different in viable and ischemic bowel, changing from the classic lymphocytic to necrotizing lesions respectively.

Abstract
Abstract
Enterocolic lymphocytic phlebitis (ELP) is a recently described entity and is of unknown etiology and pathogenesis. It is characterized by phlebitis of the bowel wall and mesentery, without arterial involvement or evidence of systemic vasculitis. The clinical presentation of ELP is varied, but it most commonly manifests with signs of an acute abdomen. Clinical, radiologic, and endoscopic findings are often conflicting and misdiagnosis is common as venous thrombosis is not suspected. The diagnosis of ELP is obtained histologically. There is a spectrum of histologic features associated with ELP, which includes lymphocytic phlebitis, necrotizing phlebitis, granulomatous phlebitis, and myointimal hyperplasia. Other features include venous thrombi and acute ischemic changes of the intestine. Surgical resection of the affected bowel is usually curative and recurrences are rare. The clinical and histopathologic features of ELP are reviewed.
