[Aneurysmal bone cysts (author's transl)].
Authors describe histological observations of 15 cases of aneurysmal bone cysts. Frequent occurrence of areas similar to giant cell tumor or solitary bone cyst was found together with fields producing chondroid intercellular substance. Attention is called to the differentiation of the two lesions described above and occasionally tumors and tumor-like conditions of chondroblastic origin. The vascular changes observed in the surroundings (arteriologsclerosis) support the earlier hypotheses attaching importance to local hemodynamic disturbance in the pathogenesis of the lesion. In certain cases penetration of aneurysmal bone cyst into the epiphyseal cartilage was found. Previous infraction or recurrence does not alter the histological picture fundamentally.
