title: Solitary rectal ulcer syndrome: an endoscopic and histological presentation and literature review.
abstract: BACKGROUND
  Although the clinicopathologic features of solitary rectal ulcer syndrome (SRUS) are well documented, the heterogeneous endoscopic appearance of lesions that the syndrome produces and its rare incidence may make for clinical confusion.
  
  
  METHODS
  Together with a literature review, we describe the variety of lesions experienced in our hospital with a series of endoscopic and histological illustrations and emphasize the diagnostic dilemma both clinically and histologically.
  
  
  CONCLUSIONS
  With comparison of different macroscopic presentations of SRUS, more correct diagnoses will be achieved and more successful treatments will be reported.
