The lateral (n=2) and posterior cervical regions (n=2) were other common neck subsites. Less commonly involved sites were the mandible (n=1), maxilla (n=1), and thyroid (n=1). A total of eight patients underwent surgery at other centers before being referred to us for further management. Out of a total 11 patients, nine patients had unresectable disease at presentation. Six of the patients with unresectable disease received a combination of weekly doses of vinblastine 6 mg/m<sup>2</sup> and methotrexate 30 mg/m<sup>2</sup> for a median duration of 6 months (range 6-18 months) followed by hormonal therapy with tamoxifen. Three patients received metronomic chemotherapy followed by hormonal therapy.

The 16-year-old patient that was presented to the emergency room with endocarditis was bodily no longer a child, although administratively and probably also psychologically, due to his Down syndrome, he was still a child. Two of the other patients, one with hemolytic anemia (2.5 years old) and one with Ewing sarcoma (4 years old), were still pre-pubertal children, while the 13-year-old minor with a septic hip was already adolescent. The author of the cited paper works in a pediatric department and reports those patients that he has seen during his work. However, in our view there is nothing specifically pediatric in his observations.
