[A rare tumor of the sciatic nerve--myxoid neurofibroma. A case report].
The surgical resection of soft tissue tumors in peripheral nerves often poses problems, since the extent of resection depends on tumor dignity, determined by incisional biopsy. This case report is about a myxoid neurofibroma of the sciatic nerve. In the literature, this rare entity is a precursor of malignant neurilemoma. The choice is difficult between radical resection in view of possible locoregional recurrence or possible malignant transformation and preservation of the nerve. In this case, the sciatic nerve was encased in the pseudocapsule of the tumor and was nearly totally spared during surgical resection. Following surgery, there were no neurological defects.
