View Original Source →Abstract
Much has been written on the subject of osteochondromas, but in the English literature there has been only one report of an osteochondroma that regressed spontaneously. For that reason, we report two additional cases of this phenomenon.
Case Details
Personal Characteristics
This boy was eleven years old
Clinical Characteristics
A solitary sessile osteochondroma was noted on the posteromedial aspect of the distal femoral metaphysis. It measured six centimeters in diameter at the base and projected 1.7 centimeters away from the cortex. The patient had been asymptomatic with regard to the osteochondroma, although the osseous projection was palpable.
Remission Characteristics
Four months later, the mass was found to be reduced in size both clinically and on radiographs. Four months after that no mass in the thigh could be palpated and the radiographs revealed only a slight cortical prominence at the previous site of the lesion. At the last evaluation, nineteen months after the first presentation, the lesion could not be identified on the radiograph.
Treatment & Mechanisms
Proposed Remission Mechanisms
Not discussed
Clinical Treatment
No therapy was recommended.
Additional Notes
Much has been written on the subject of osteochondromas, but in the English literature there has been only one report of an osteochondroma that regressed spontaneously. For that reason, we report two additional cases of this phenomenon.
