[Epiphyseal chondroblastoma: natural history and clinico-radiographic aspects].

: The authors intend to supply a wide and valid framing of the present knowledges about epiphysis blastoma, excluding the therapeutical problems. After a short historical note, they illustrate the elements of natural history, search into the radiologic and anatomo-pathologic aspects of such neoplasia with the differential diagnoses involved, and, at last, discuss the histogenetic hypotheses. The analysis of the classic and unusual evolutive aspects is set forth as a conclusion of the work.
