The duration of symptoms preceding a definitive diagnosis of osteosarcoma is quite long. Pathological radiological signs are often evident by the time of diagnosis. Although several case reports have been published on osteosarcoma of the femur, to the best of our knowledge this report is the first one with such an unusual clinical course.

Case presentation

We describe the case of a 58-year-old Caucasian man who presented with a femoral shaft fracture. Two years post-trauma osteosarcoma in the ipsilateral distal femur was diagnosed. Was it coincidence? We think that the history of the trauma is crucial to answering this question.


This case report underlines the need to keep up awareness of pathological fractures in emergency medicine and trauma surgery. When radiographs do not raise any suspicion but the history of trauma or the physical examination does, we recommend further radiological and/or histological diagnostic examinations.
