Presentación de casos clínicos RESUMENEl lipoblastoma forma parte de los tumores derivados del tejido adiposo. Es una neoplasia benigna que se puede presentar de forma localizada o difusa, que afecta a niños en la primera infancia y que, generalmente, se localiza en el tronco y las extremidades. Estos tumores son poco frecuentes en la edad pediátrica, pero cuando uno de ellos se presenta, constituye un desafío que se debe resolver rápidamente por el riesgo de malignidad que implican otras lesiones neoplásicas, de similares características. El diagnóstico preoperatorio es dificultoso, ya que los métodos por imágenes no aportan información específica que permita diferenciarlos de otros tumores, como los liposarcomas. El diagnóstico definitivo es anatomopalógico y, en casos dudosos, es necesaria la confirmación citogenética. Se presenta el caso de un niño de 14 meses de edad con diagnóstico de lipoblastoma de localización retroperitoneal de gran tamaño. Palabras clave: neoplasias retroperitoneales, lipoblastoma, pediatría.ABSTRACT 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. Lipoblastoma retroperitoneal gigante. Caso clínico Giant retroperitoneal lipoblastoma. Case report INTRODUCCIÓNLos tumores adiposos se clasifican como b e n i g n o s : l i p o m a , l i p o m a h e t e r o t ó p i c o , lipomatosis, hibernoma y variantes de lipoma, como lipoblastoma y lipoblastomatosis (LBS); o malignos: liposarcoma, que es extremadamente raro en la infancia.

“…Lipoblastoma is a rare benign soft tissue tumor that occurs most commonly in infants and children. [ 1 , 2 ] The vast majority are detected in children <3 years of age, with >80% of cases occurring before the age of 3 and 40% before the age of 1. Approximately 70% of these tumors occur in the extremities, trunk, head, and neck.…”

Introduction:Lipoblastoma is a rare benign soft tissue tumor that occurs most commonly in infants and children. However, retroperitoneal lipoblastomas are rare, occurring in <5% of cases. We report a case of large retroperitoneal lipoblastoma and the largest collection of known retroperitoneal lipoblastomas in children in the literature.Case presentation:A 3-year-old girl presented with left abdominal mass. Magnetic resonance imaging (MRI) revealed a soft tissue mass measuring 12 × 8 × 6 cm in the retroperitoneal region. The mass had a clearly defined margin and a reticular pattern with an interposing fat component. Based on these findings, the mass was suspected to be a soft-tissue tumor, most likely lipoblastoma.Laparotomy with resection of the retroperitoneal mass was performed. The tumor was easily dissected from the retroperitoneal space without injury to surrounding structure.A histopathological examination demonstrated the mature proliferation of adipocytes and spindle-shaped cells separated by fibrovascular septa accompanied by myxoid changes. The cells were separated into lobules by septa, and areas of immature adipocytes showing a signet-ring or multivacuolar appearance were present at the periphery. Histopathological diagnosis was lipoblastoma. Follow-up at 6 months revealed no evidence of recurrence.Conclusion:Retroperitoneal lipoblastoma is rare and tends to be large in size when diagnosed at presentation. Complete resection should not be delayed, as impingement on the surrounding structures is imminent.
