Case Reports
Funding: this study was supported by research grants from the Swedish Childhood Cancer Fund (grant number KP2016-0031, PR2016-0115), the Swedish Cancer Society (grant number CAN 2017/704), Radiumhemmets Research Funds (grant number 201313, 181272), the Stockholm county council (grant number 20160626) and Karolinska Institutet (grant number 2020-00339) (to KARW). The funding sources have played no role in the research design, analysis or reporting.
Ethical approval: ethical approval for the study of children undergo- ing gonadal tissue cryopreservation aiming at fertility preservation and for the follow-up of patients to adulthood was granted by the Ethical Review Board of Karolinska University Hospital (Dnr. 427/03) and the Regional Ethics Committee of Stockholm (Dnr. 2011/1158-31/2, 2014/470-32, 2016/2530-32 and 2018/2255-32). The patient has given her written informed consent to publish and discuss the case and the pictures here included. The patient has also read and approved the submission of this manuscript.
