Foam cell transformation in periapical lesions of endodontic origin

Extensive foam cell aggregates are infrequently encountered in lesions of endodontic origin and, when present in quantity, may suggest to the pathologist a bone localizatiorl of a reactive or proliferative process. Correlation of clinical and radiographic data and an appreciation for the presence of xantlaomatoid histiocytes in periapical processes of diverse etiology, including endodontic causes, will allow a definitive diagnosis to be made.
