Abstract

|
|
A rare case of malignant schwannoma is reported in which the patient, a 50 year-old man, received repeated surgical operations for frequent recurrences of the tumor masses in thoracolumbar region of his back. The masses were in the paravertebral, with involvement of spine compressing the cord acid of neighbouring tissues and structures.. Siinpre X-rays demonstrated a compression of the body of L, vertebra along with destruction.of the spinous ´processes of T12 and L1.
At operation, most´´ of the accessible .tumor tissue was -removed and an adequate decompression achieved for spinal cord. Histological studies of each specimens revealed malignant schwannoma involving the spine and surrounding tissues. According to pathological finding maligant schwannoma was confirmed. Malignant peripheral nerve tumors are very rare and highly malignant.
They must be treated by surgical measures either by radical local resection or amputation when necessery. Radical local excision might be applicable as the first attempt on a low grade tumor while an amputation might be a necessery procedure for recurrent tumor or for one showing a high grade of malignancy. Radical excision at the first attempt at eradication is often the only golden opportunity for permanent cure. The high rate of local recurrence after inadequate excision has been emphasized.
