Barrett’s esophagus with epithelial changes indefinite for dysplasia. (A) and (B) This biopsy shows a few distinct glands lined by epithelial cells with dark and enlarged nuclei (H&E stain; (A) magnification 100×; (B) magnification 200×). There is no surface present and thus it is best interpreted as indefinite for dysplasia. (C) and (D) This biopsy show a distinct single gland lined by epithelial cells with dark, enlarged, and pleomorphic nuclei (H&E stain; (C) magnification 200×; (D) magnification 400×). This case may be interpreted as indefinite for dysplasia due to the extremely limited nature of the biopsy.
