The spectrum of eosinophilic infiltration of the gastrointestinal tract and its relationship to other disorders of angiitis and granulomatosis

Hum Pathol. 1979 Jan;10(1):31-43. doi: 10.1016/s0046-8177(79)80070-2.

Abstract

Six cases of eosinophilic infiltration of the gastrointestinal tract were studied. Three cases were of the diffuse infiltrative variety (eosinophilic enteritis, two cases; eosinophilic peritonitis, one case), and three cases were of the circumscribed variety (so-called inflammatory fibroid polyp). Two of the infiltrative lesions showed necrotizing granulomas identical to those described by Churg and Strauss; one of the two also showed active vasculitis. One circumscribed lesion occurred in a patient with polyarteritis nodosa. Necrotizing eosinophilic granulomas were also noted in this lesion. Our observations suggest that the two forms of eosinophilic infiltration of the gastrointestinal tract are parts of a disease spectrum. Supporting evidence in the literature is presented. The relationship of this group of eosinophilic lesions to the hypereosinophilic syndrome, allergic granulomatosis and angiitis of Churg and Strauss, and polyarteritis nodosa is discussed.
