(A) Endoscopic photograph of a small (<1.0 cm) sessile adenoma-like DALM in a patient with CUC. This polyp was located within an area of histologically confirmed chronic inactive colitis. The patient underwent a polypectomy and had no evidence of neoplasia at 4.2-year follow-up. (B) Histological appearance of the polyp shown in A. The lesion shows a tubular arrangement of dysplastic epithelium similar to a non–CUC-related sporadic adenoma. The epithelium is composed of basally oriented, slightly pseudostratified cells with pencil-shaped hyperchromatic nuclei, increased mitotic figures, mucin depletion, and a lack of surface maturation, all typical features of low-grade dysplasia. All of the epithelium in this photograph is dysplastic (H&E; original magnification 200×).
