Background. Preservation of the nerve and shoulder joint function is important in patients who undergo excision of superior sulcus tumors. Case. A 25-year-old woman diagnosed with neurofibromatosis type 1 in childhood presented with a 1-year history of left shoulder dullness. The shoulder pain worsened, and chest computed tomography revealed a tumor (51×42 mm) originating from the left superior sulcus. Magnetic resonance imaging revealed that the tumor had increased in size from 35 to 51 mm within a year. The tumor was successfully excised via a transmanubrial approach under electrophysiological monitoring without any brachial plexus injury. A histopathological evaluation indicated a malignant peripheral nerve sheath tumor. We observed no postoperative complications, including neurological injury. The patient was followed up and showed no recurrence over 2 years. Conclusion. We recommend the transmanubrial approach as a valuable operative procedure for excision of nerve sheath tumors originating from the superior sulcus. Notably, electrophysiological monitoring is important to avoid peripheral nerve injuries.
