Very late local recurrence of Ewing's sarcoma--can you ever say 'cured'? A report of two cases and literature review.
We report two rare cases of very late local recurrence of Ewing's sarcoma, occurring 16 years and 19 years after treatment of the primary tumour. In both cases, disease remission had been achieved. Both patients originally underwent non-surgical combined modality therapy following initial diagnosis and both were rendered disease-free. After a long latent phase, both started experiencing unexplained local symptoms. These were investigated at their local hospital but tumour recurrence was not initially considered as a cause of these symptoms. The two patients were eventually referred back to our institution after the diagnosis of recurrent Ewing's sarcoma was established. Both have successfully undergone complete excision of the recurrences and are receiving postoperative adjuvant therapy. These cases highlight the need to remain vigilant for local recurrence, however long after the initial diagnosis.
