[Giant retroperitoneal lipoblastoma. Case report]

Area of Science:

• Pediatric Oncology
• Surgical Pathology
• Diagnostic Imaging

Background:

• Lipoblastoma is a rare, benign tumor originating from adipose tissue, primarily affecting infants and young children.
• These neoplasms typically present in the trunk and extremities but can occur in other locations.
• Differentiating lipoblastoma from malignant soft tissue tumors, such as liposarcoma, is clinically significant due to potential for malignancy.

Observation:

• Preoperative diagnosis of lipoblastoma is challenging as imaging modalities lack specificity.
• The case involves a 14-month-old boy with a large retroperitoneal lipoblastoma.
• Similar-appearing neoplastic lesions necessitate prompt and accurate diagnosis.

Findings:

• Definitive diagnosis of lipoblastoma relies on anatomopathological examination.
• Cytogenetic analysis may be required in ambiguous cases to confirm the diagnosis.
• The presented case highlights the diagnostic difficulties associated with large, retroperitoneal lipoblastomas in pediatric patients.

Implications:

• Accurate and timely diagnosis of pediatric lipoblastoma is essential to guide appropriate management.
• Distinguishing benign lipoblastoma from malignant tumors prevents unnecessary aggressive treatment.
• Further research into specific diagnostic markers could improve preoperative differentiation of pediatric adipose tumors.
