[Mural ameloblastoma].

All materials of 14 cases of mural ameloblastoma from 1968 to 1987 in our hospital were reviewed and pathologic characteristics of the tumor were suggested. The mural ameloblastoma may be classified into three categories: (1) inside of cyst; (2) inside of wall and (3) mixed type. Their representations were plexiform, follicular and mixed type in histopathology. The pathologic classification is of value on choice of clinical therapy and prognosis. The tumor recurs readily after simple curettage.
