Fibroblastoma that is primary within the brain substance is rare. We know of only three reported instances that have been verified histologically: that of Mallory, reported recently by Bailey,1 a case of Bailey's and a recent case reported briefly by Tracy Mallory.2 We have had the opportunity recently to study such a tumor removed at operation, and we report it because of its rarity and because of the interesting and important theoretical questions aroused by the study of the pathologic specimen.
