[Sacrococcygeal chordomas--peculiarities of their morphology, clinical aspects, diagnosis and therapy].

Sacro-coccygeal chordomas are discussed with respect to particularities of their morphology, clinical aspects, diagnosis and therapy, including two cases treated by the authors. The consideration of almost always ignored or misinterpreted initial lumboischialgia is pointed out. Because of the primary benign growth of these tumours, early diagnosis and immediate radical surgical treatment would possibly increase the survival chance of their carriers or even--so far only a speculation--lead to permanent curing.
