Giant cell tumor of soft parts is a rare neoplasm that mainly affects
adulst and the elderly and is usually located in the extremities. Here we report a
child with giant cell tumor of soft tissue, which is a very rare condition in childhood.
Clinical presentation: A 5 year old girl presented with a 5 month history of left
lower extremity pain. She had developed paraplegia before admission. On
examination, mild left lumbosacral swelling and tenderness was found. Abdominal
and pelvic CT-Scan revealed an expansile lytic lesion of the left side of sacrum with
significant soft tissue component extending toward the left iliac bone. Lumbar MRI
revealed a space occupying lesion originating from posterior L5 elements, projecting
toward the L1.
Intervention: The patient underwent surgery. A firm epidural hemorrhagic tumor of
L5, S1, and S2 with no spinal cord involvement was found. Partial tumor resection
(measuring 3*1*0.5 cm in maximal diameter) and laminectomy was done.
Conclusion: Primary giant cell tumors of soft tissue are distinctive, rare neoplasms
that exhibit a wide clinicopathologic spectrum similar to osseous GCTs and need to
be differentiated from other giant cell rich soft tissue tumors. Recognition of this
tumor is important due to its behavior as a low grade malignancy, but this cannot be
predicted and metastasis does occur rarely.
