Rare case of thigh lipoblastoma in an infant: A case report.

INTRODUCTION AND IMPORTANCE

Lipoblastoma is a rare, benign tumor that primarily affects infants and young children, representing a small percentage of soft tissue tumors in this population. Its early diagnosis and surgical management are crucial for favorable outcomes, as lipoblastoma can lead to significant complications if left untreated.

CASE PRESENTATION

We report the case of an 18-month-old female toddler who presented with a progressively growing, painless mass in the left medial thigh, which had developed over six months. Imaging studies, including CT and MRI, revealed a well-defined, hypodense lobulated mass consistent with lipoblastoma. Surgical excision was performed, and the mass measured approximately 7 by 6 cm. Histopathological examination confirmed the diagnosis of lipoblastoma. The patient experienced a successful recovery without recurrence during a one-year follow-up period.

DISCUSSION

Lipoblastoma typically presents as a painless subcutaneous soft tissue mass that progressively grows. Symptoms often relate to the tumor's location and size or the mass effect on surrounding structures. Imaging studies, particularly CT and MRI, play a crucial role in making a presumptive diagnosis by revealing the tumor's characteristics and components. Total excision remains the treatment of choice for lipoblastoma.

CONCLUSION

Lipoblastoma should be included in the differential diagnosis of rapidly growing, painless masses in children under three years of age. The treatment of choice is complete surgical resection of the tumor, which is crucial for achieving favorable outcomes and reducing recurrence risk.
