Thevulnerability of the trigonum has been the subject of animated discussion.From the review of a large number of recorded cases it may be concludedthat the trigonum is infrequently affected alone. It is, however, often involvedwith the base or the ureters. The papillomata of the base often extend tothe posterior or either lateral wall. Such tumors, limited to the posteriorwall, are, however, not uncommon. Somewhat rarer are growths upon thelateral wall, the vault, or the anterior wall.
