Giant Schwannoma on Thenar Aspect of the Hand: A Rare Case Report.

Schwannomas are the most common benign tumors of peripheral nerves but are rare in adults. They have an extremely slow rate of growth before the onset of symptoms such as pain, paresthesia, and tingling. Giant schwannomas of the extremities can significantly affect the quality of life. With a correct diagnosis, the tumor can be extirpated with preservation of nerve function and a very low risk of recurrence. A case of a symptomatic giant schwannoma on thenar eminence of the right hand in an adult male is discussed in this report.
