HighlightsThis is an advanced case of aggressive GCT of calcaneus.It is not only a rare case but also an interesting diagnosis and surgical management.Limb salvage surgery which consists of wide excision-total calcaneoctomy, followed by reconstruction with femoral head allograft and soft tissue coverage with sural flap is a good option.

Lipoblastoma is a benign lesion of immature fat cells that is found almost exclusively in pediatric population. This tumor is a rare tumor that occurs in infancy and early childhood, accounting for less than 1% of all childhood neoplasm. It is more common in male than in female and often presents as an asymptomatic, rapidly enlarging, soft lobular mass on the extremity. Although benign, it gives great difficulty in its management, due to its extensions into different facial planes, especially in lipoblastomatosis. Thus, complete surgical excision is the treatment of choice.
