Abstract
The aim of our study is to present osteoid osteoma as a disease in preschool children. O O is a benign inflammatory process that is characterized from osteoid formation. It appears mainly in the second and third decade of life, while before 5 years of age usually as case reports. The clinical and radiological presentation must be differentiated from trauma, osteomyelitis, malignancy and other benign diseases.
We present three patients, aged ranging from 18 months to 4 years old, that were treated surgically for the removal of O O in the tibia and fibula. All patients presented with limping, pain mainly in the night, gradual restriction of activities. The clinical, hematological and radiological investigation revealed the general aspects of the disease. Bone scans were positive in all. CT scan confirmed the diagnosis in all three patients. Surgical treatment was done with fluoroscopic assistance, in order to remove the minimum possible amount of bone. In two patients the lesion was located in the distal metaphysis of the tibia and in one in the distal metaphysis of the fibula.
The diagnosis was confirmed with the typical nidus, in pathological specimens. In one patient the lesion was intracortical and in two in the medullary area. Despite the ages of our patients, there were not misleading findings, in the specimens. After surgery the patients were symptoms free, and with 1–4 years follow up, there are no recurrences.
We conclude that osteoid osteoma must be included in the differential diagnosis, in cases of pain and limping, in preschool children.
