The “disappearing” Osteochondroma
Skeletal Radiology 10: 1983; 40-42
View Original Source →Abstract
Spontaneous regression of a solitary osteochondroma is described. This regression apparently resulted from a cessation of growth of the osteochondroma prior to skeletal maturation, with subsequent incorporation of the lesion into the enlarging bony metaphysis.
Case Details
Personal Characteristics
A 9-year-old boy
Clinical Characteristics
Presented with a palpable mass above the left knee
Remission Characteristics
Spontaneous regression of a solitary osteochondroma is described. This regression apparently resulted from a cessation of growth of the osteochondroma prior to skeletal maturation, with subsequent incorporation of the lesion into the enlarging bony metaphysis.
Treatment & Mechanisms
Proposed Remission Mechanisms
Cessation of growth of the osteochondroma prior to skeletal maturation, with subsequent incorporation of the lesion into the enlarging bony metaphysis
Non-Clinical Treatment
The lesion was followed with annual radiographs, over a six-year period, without treatment
Additional Notes
The ossified portion of the osteochondroma was observed to grow rapidly during the first two years. A short interval of apparent stability was then followed by progressive reduction in size of the lesion.
