Abstract

Caff Giuseppe, Campanacci Domenico Andrea and Capanna Rodolfo

In international literature, several cases of multicentric osteoid osteoma have been described. Clinical presentations with a double nidus in the same bone, in adjacent bones or in symmetric bones have been reported.In the present study the authors report a case of an osteoid osteoma of the right distal femur in a forty-five years old man with a history of osteoid osteoma of the left distal femur treated thirty-four years earlier. To our knowledge, only two similar cases were known so far.
