Schwannoma is a slow-growing benign tumor of the peripheral nerve that frequently occurs in the region of the head, neck and spine. We present a 50-year-old male patient diagnosed and operated for schwannoma of the ulnar nerve in the distal part of the left forearm. In the case of a palpable limb mass, one of the possible diagnoses is schwannoma, and since operative technique is somewhat specific with tumor enucleation and internal neurolysis, it is crucial to preoperatively keep in mind schwannoma as a possible diagnosis.
