Surviving cancer or future motherhood? Both are possible: an Ewing sarcoma case in an 8-year-old girl.

Ewing's sarcoma is an aggressive tumour, common in paediatric age, in which treatment often implies a decrease in reproductive potential. We describe a case of a woman who had a lumbar Ewing's Sarcoma in 1991, at the age of 8. She was submitted to extended tumourectomy, chemotherapy and local radiotherapy without preservation techniques. In adult life, and after two in vitro fertilization (IVF) reproductive cycles without success, she spontaneously conceived at the age of 32. After an uneventful pregnancy, she delivered a healthy child by caesarean section. This is a rare successful case of a spontaneous and uneventful pregnancy without previous preservation techniques. In the last 30 years, there has been significant development in this area, and currently, there are solutions for these patients, including in prepubertal age.
