Statement of Ethics
Written informed consent was obtained from the patient for the
publication of these case reports and any accompanying images. Ethics
committee approval was not obtained because we report a clinical case of
only two patients, we have not included any identifiable information,
and we obtained written consent for publication from the patient’s
parents according to the 1964 Helsinki Declaration and its later
amendments or comparable ethical standards. This retrospective review of
patient data did not require ethical approval in accordance with local
guidelines.
