A man aged twenty complained of increasing pain and swelling in the left thigh of one year duration. The pain was severe at night. On examination there was palpable sclerotic swelling over the posterior and lateral aspect of the mid-shaft of the femur. A radiograph showed a fusiform enlargement of the mid-shaft of the femur with dense cortical thickening and sclerosis around a small cavity of an osteoid osteoma.
At operation the lesion was excised from the femur in a block of bone. Histological examination confirmed the diagnosis of osteoid osteoma. Since operation the patient has remained free from symptoms.
