Recurrent osteoid osteoma. Case report with a ten-year asymptomatic interval.

Osteoid osteoma has been accepted as a distinct clinical and pathologic entity for more than 50 years. Surgical curettage will often cure the lesion, although en bloc excision is now the preferred treatment. The development of local recurrence after surgery, although rare, has been well documented after both curettage and en bloc excision. Symptomatic recurrence of an osteoid osteoma was seen ten years after surgical curettage. Its occurrence at the same site as the original lesion is consistent with the concept that it had originated from residual tissue and is in keeping with the concept of osteoid osteoma as a benign tumor.
