The outstanding features of this case are as follows:
1. Onset of the tumor at the age of fifty-eight.
2. Trauma antecedent to the onset of the tumor.
3. Presence of pathological fracture, symptomatic of weak periosteal reaction.
4. Intactness of the articular surfaces, characteristic of osteogenic tumor.
5. Typical destruction of cortex in one portion of the bone.
6. Histological examination of the involved bone showing irregular decalcification, break in cortex, invasion, and condensation.
7. Postoperative survival of nine years (January 25, 1935) and no noticeable signs of metastases.
