Abstract: We report a case of a female patient that presented in our outpatient department with notable muscle weakness in her right arm during the last year. Careful clinical examination revealed a palpable mass on the medial side of the right distal humerus with positive tinel sign and paresthesias along the ulnar side of her forearm. Magnetic resonance imaging showed a soft-tissue mass with 3.8 X 2.4 cm size possibly emerging from the right ulnar nerve just proximal to the elbow joint. Excisional biopsy confirmed the diagnosis of a rare type of ulnar’s nerve schwannoma. Histologically the mass consisted of typical Antoni A areas with no signs of axon differentiation, whereas the immune histo chemistry examination revealed Schwann cell origin. Fourteen months post-operatively the patient has no motor weakness or paraesthesias and is very satisfied with the outcome.
