An 18 years old male was referred to us 4 years after major tumoral surgery. In 2002 he was diagnosed with Ewing sarcoma of the proximal two–thirds of his left femur. Wide resection of the tumor was performed, with a makeshift implant one–stage reconstruction, followed by a combination of chemo and radiotherapy for another 6 months.

Eight months after surgery a deep infection of the hip developed, and despite antibiotic treatment and two consecutive debridments and lavage the results were negative. When we first saw the patient in 2006, he still had an active infection in his left hip and a septic general appearance. A two–stage revision was performed and a modular tumoral reconstruction was implanted. At two years follow up the patient presents no signs of recurrence neither of the infection nor of the primary tumor.
