Local recurrence can happen in up to 80% of incompletely resected tumours. Therefore, complete surgical resection is required to prevent recurrence. It arises from embyronic white fat that is rapidly enlarging. Most common locations are at the trunk and extremities.<ref name="pmid29343278">{{cite journal | vauthors = Abdul-Ghafar J, Ahmad Z, Tariq MU, Kayani N, Uddin N | title = Lipoblastoma: a clinicopathologic review of 23 cases from a major tertiary care center plus detailed review of literature | journal = BMC Research Notes | volume = 11 | issue = 1 | pages = 42 | date = January 2018 | pmid = 29343278 | pmc = 5773143 | doi = 10.1186/s13104-018-3153-8 | url = | doi-access = free }}</ref>
