Giant retroperitoneal lipoblastoma. Case report

Lipoblastoma is part of tumors derived from adipose tissue. It is a benign neoplasm that can be localized or diffuse, affecting children in early childhood and usually located in the trunk and extremities. These tumors are uncommon in the pediatric age, but when one of them is present, it is a challenge that we must resolve quickly due to the risk of malignancy that involves other similar neoplastic lesions. The preoperative diagnosis is difficult, because the imaging methods do not provide specific information that allows us to differentiate them from other tumors, such as liposarcomas. The definitive diagnosis is anatomopathological and, in doubtful cases, cytogenetic confirmation is necessary. We present the case of a 14-month-old boy with diagnosis of large sized lipoblastoma of retroperitoneal localization.
