TY - JOUR T1 - Non-neoplastic colorectal disease biopsies: evaluation and differential diagnosis JF - Journal of Clinical Pathology JO - J Clin Pathol SP - 783 LP - 792 DO - 10.1136/jclinpath-2020-206794 VL - 73 IS - 12 AU - Michelle Moore AU - Roger M Feakins AU - Gregory Y Lauwers Y1 - 2020/12/01 UR - http://jcp.bmj.com/content/73/12/783.abstract N2 - A wide variety of non-neoplastic conditions may be encountered on colorectal biopsy encompassing idiopathic, infectious, vascular and immune-mediated aetiologies. Although interpretation of such biopsies may be challenging, appreciation of the dominant pattern of injury and subsequent host response may allow for a more focused histological diagnosis in the correct clinical and endoscopic setting. This article aims to provide a systematic, methodical approach to the assessment of such biopsies, concentrating mainly on diagnoses other than inflammatory bowel disease. ER -
