FOCAL ULCERATIONS OF THE COLON IN GRANULOMATOUS COLITIS

Abstract
Two cases of granulomatous colitis that involved short segments of bowel are presented. These illustrate that focal, eccentric, ulcerating lesions are one part of the spectrum of colon involvement that also includes universal colon disease. On roentgenograms, sharp overhanging margins of the ulcers did not appear to project beyond the lumen of the colon. Histologic examination showed that the ulcers arose on a mound of tissue composed of edematous submucosa and muscularis infiltrated by inflammatory cells. This mound projected into the lumen of the bowel. Correlative results between roentgenographic and histologic examinations are presented.
