Insights
A rare benign lipoblastoma in a two-year-old girl
Area of Science:
- Hand surgery
- Pediatric oncology
- Soft tissue tumors
Background:
- Lipoblastoma is a rare, benign tumor of infancy and childhood, typically presenting as a soft tissue mass.
- While benign, lipoblastomas can grow significantly, posing challenges in pediatric cases.
- Surgical excision is the primary treatment for symptomatic lipoblastomas.
Observation:
- A two-year-old female presented with a large, slow-growing soft tissue mass between the second and third metacarpals of her right hand.
- The mass was consistent with a lipoblastoma.
- Surgical intervention was planned for mass excision and functional reconstruction.
Findings:
- The lipoblastoma was successfully excised.
- The deep transverse metacarpal ligament (DTML), essential for hand stability, was reconstructed.
- A free tendon graft from the extensor indicis propius (EIP) was utilized for DTML reconstruction.
Implications:
- This case highlights successful management of a large pediatric hand lipoblastoma.
- Demonstrates the feasibility of using extensor indicis propius tendon grafts for deep transverse metacarpal ligament reconstruction.
- Offers insights into surgical techniques for preserving hand function after benign tumor excision in children.
Abstract:
Lipoblastoma of the hand is a rare benign tumour of infancy. Although benign, the tumour can present as a large mass. We present a case of a two-year-old female with a large, slowly growing soft tissue mass between the second and third metacarpal of the right hand. After excision of the mass, the deep transverse metacarpal ligament (DTML) was reconstructed using a free tendon graft from the extensor indicis propius (EIP).
