MULTIPLE RECURRENT BENIGN SCHWANNOMAS OF DEEP AND SUPERFICIAL NERVES OF THE UPPER EXTREMITY - A NEW VARIANT OF SEGMENTAL NEUROFIBROMATOSIS

Benign schwannomas of the brachial plexus are uncommon tumors, first d escribed in the late 19th century. These lesions, which are histologic ally benign, can generally be excised without sacrifice of neural elem ents. We present the first known case of multiple concurrent and recur rent benign schwannomas of the upper extremity in an individual who de monstrated no other evidence of neurofibromatosis, and we suggest that this case may represent a new subtype of type V neurofibromatosis.
