It is well-known that neurilemoma is benign nerve tumor originated from Schwann cell. We reported four cases of this tumor.
Case 1 female, aged 56. The tumor of 6×5cm in size involved right sciatic nerve.
Case 2 male, aged 42. The tumor of 6.5×5cm developed from left femoral nerve in the pelvic cavity. The cross section showed the secondary changes as multi-cystic structure filled with light yellowish serous fluid and deposit of haemosiderin.
Case 3 male, aged 44. The tumor located in left common peroneal nerve.
Case 4 female, aged 47. The tumor developed from the cutaneous nerve of the skull. Microscopically, those cases were distinguished as neurilemoma.
Case 1 and 3 were composed of both of Antoni type A and B tissues.
Case 2 had the microscopic findings of Antoni type A and B and also of massive secondary changes as hyalinization of the vessels, cysts and deposit of haemosiderin. Case 4 was mostly composed of Antoni type B tissue.
