A 46-year-old man was found to have occult blood in the stool in our hospital. A barium enema study revealed regional stenosis of approximately 8 cm of the ascending colon. Furthermore, the colon was found to have a thickening of three layers by abdominal CT scanning. The elevated value of the serum IgE was 1730 EU. Under a tentative diagnosis of an infectious or an allergic colitis, partial resection was performed. The pathological postoperastive diagnosis was allergic granulomatous angitis (AGA) with eosinophilic infiltration at the predominant subserosal lesion. Colonic stenosis caused by AGA is very rare in Japan. We report the experience performing an operation without a diagnosis established preoperatively.
