Resolving Solitary Osteochondromas; A Report Of Two Cases And Literature Review
Orthopedics 12(6): Jun 1989; 861-863
View Original Source →Abstract
Resolving osteochondromas were previously thought to be uncommon. Two cases are presented, including the first report of a resolving solitary osteochondroma of the proximal tibia. These cases, along with previous reports, suggest resolution may occur, especially in boys under age 12 years. Surgical excision should be delayed in this group of patients provided malignant transformation or neurovascular compromise is not a concern.
Case Details
Personal Characteristics
11-year-old boy with no family history of osteochondromas
Clinical Characteristics
Nonpainful mass in the proximal portion of his left arm
Remission Characteristics
Twenty-one months later, the mass was still palpable but appeared smaller on the radiograph. At 32 months, the mass was difficult to palpate. Radiographs showed continued resolution of the tumor. By 68 months, the mass was no longer palpable. Only a small osteochondroma remnant and slight widening of the shaft remained.
Treatment & Mechanisms
Proposed Remission Mechanisms
Not discussed
