			<pre>
			Polyps, Cecum, Polypectomy:
			- Fragments of colorectal-type mucosa with cryptitis and crypt
			abscesses, see note.
			- NEGATIVE for dysplasia.

			Note:
			The possibility of an underlying inflammatory process involving the GI tract should be considered. The above findings should be correlated with the clinical findings and overall endoscopic impression.

	The biopsy shows abundant intraepithelial lymphocytes with a preserved crypt architecture. No thick subepithelial band of collagen is present. No granulomas are identified. The main histomorphologic differential diagnoses include resolving infection and early inflammatory bowel disease.

			== Isolated crypt abscess ==

			<pre>
			COLON, BIOPSY:
			- ONE ISOLATED CRYPT ABSCESS, ON THE BACKGROUND OF COLONIC MUCOSA WITHOUT SIGNIFICANT
			PATHOLOGY, SEE COMMENT.
			- NEGATIVE FOR LYMPHOCYTIC COLITIS AND NEGATIVE FOR COLLAGENOUS COLITIS.
			- NEGATIVE FOR DYSPLASIA.

			COMMENT:
			The significance of the crypt abscess is unknown, as the background colon is not
			significantly inflamed. A definite cryptitis elsewhere is not identified. Architectural
			changes are not apparent. Clinical correlation is suggested.

	The biopsies show features of chronicity and would be consistent with inflammatory bowel disease (IBD), a drug reaction, and chronic infection. There are no eosinophilic abscesses, as previously noted (see report for specimen S11-3965) and severe inflammation with ulceration. These findings make an eosinophilic enterocolitis unlikely. In the context of an IBD diagnosis, histologic features would favour ulcerative colitis over Crohn's disease.
