SCHWANNOMA OF THE ULNAR NERVE: A CASE REPORT

Dr. Amit Bikram Shah*, Dr. Amit Limbu, Dr. Amit Sethia and Dr. Ritesh Thapaliya

ABSTRACT

Schwannomas, also known as neurilemmoma, are benign tumors originating from Schwann cells along the course of a nerve. They are the commonest tumors of peripheral nerves, although the incidence in adults is only 5%[1] and upper limb schwannomas contribute 19% of them.[2] The growth of these tumors is slow, so they can remain as painless swellings for a few years before other symptoms appear.[3] There is a higher incidence in the flexor surface of the upper limb, since the concentration of nerve fibers is higher over that region.[4] Usually, this tends to occur in patients aged 30–60 years and has no race or sex predisposition.[5-7] As they usually grow slowly and appear as painless swellings it may take many years before being correctly diagnosed.[8,9] The onset of symptoms is usually associated with location rather than the size of the tumor as symptoms of neural compression arise with the growth of the mass.[10]
