Schwannoma is a relatively uncommon, slow-growing, benign tumor that is derived apparently from the Schwann cells lining the nerve sheath. Its most common locations are the flexor surfaces of the extremities, neck, mediastinum, retroperitoneum, posterior spinal roots, and cerebellopontine angle, the occurrence on the lower limbs accounts for 1% of all cases. Ancient schwannoma is considered as a variant of schwannoma, comprising about 10% of all schwannomas. The long-standing schwannoma attributes to degenerative changes and is termed "ancient" schwannoma. We report a rare case of ancient schwannoma of the calf region in a 10-year-old child.
