Neurilemmoma is a benign neoplasm arising from the Schwann cell of the nerve sheath. They are usually painless and are most common in the upper extremity. Pathologically, neurilemmoma is encapsulated and made up of organized elements: the Antoni A cells, the Antoni B cells and the Verocay bodies. Two cases of solitary benign neurilemmoma of the sciatic nerve are presented with a review of the literature. Tumors were completely enucleated and confirmed by pathological examination. The post-operative course has been satisfactory showing no recurrence for the period of more than one year.
