Giant lower back lipoma in pediatric: a case report

Backgrounds: Lipoma is the most common soft-tissue mesenchymal neoplasm in adults. Lipoma that sized over 10 cm and weighed over 1000 grams is considered giant lipoma. Giant lipoma, especially in children are rare, so it represents a real diagnostic and therapeutic challenge. In this case report, we report a further case. Case: A three-year-old girl with a history of progressive growing mass on the lower back since born resulting in pain. CT scan with contrast shows a soft tissue mass with fat content sized 6,1 x 12,1 x 12,7 cm without contrast enhancement. Surgical excision was performed to remove the tumor completely. Histopathology examination confirmed the diagnosis of lipoma. Discussion: Tumor location, size, and clinical symptoms decide the treatment of intramuscular lipoma. The ultimate treatment of a giant lipoma is wide surgical excision, because this large tumor may undergo malignant transformation. Conclusion: Pediatric giant lipomas are rare, and when they present, an appropriate workup must be done. This should be followed by adequate open surgical excision and repeat examination over time to monitor for recurrence.
