TY - JOUR T1 - An approach to duodenal biopsies JF - Journal of Clinical Pathology JO - J Clin Pathol SP - 1133 LP - 1150 DO - 10.1136/jcp.2005.031260 VL - 59 IS - 11 AU - S Serra AU - P A Jani Y1 - 2006/11/01 UR - http://jcp.bmj.com/content/59/11/1133.abstract N2 - The introduction of endoscopy of the upper digestive tract as a routine diagnostic procedure has increased the number of duodenal biopsy specimens. Consequently, the pathologist is often asked to evaluate them. In this review, a practical approach to the evaluation of a duodenal biopsy specimen is discussed. An overview of the handling of specimens is given and the normal histology and commonly encountered diseases are discussed. Finally, a description of commonly seen infections is provided, together with an algorithmic approach for diagnosis. ER -
