Mucosal prolapse syndrome--a unifying concept for solitary ulcer syndrome and related disorders.

Abstract

Nineteen cases of classical solitary ulcer of the rectum syndrome (SURS) and sixteen examples of rectal mucosal prolapse are described. Similarities in the histological and histochemical features of the two groups lead us to suggest that the term "mucosal prolapse syndrome" be used to describe this group of disorders in which mucosal prolapse--overt or occult is the common underlying pathogenetic mechanism.
