ABSTRACT
Schwannoma is the most common tumor of the peripheral nerves, the malignant transformation is extremely rare, the tumors are composed of Schwann cells, which support the peripheral nerve fibers and are of neuroectodermal origin. Objective: Presentation of the clinical case of a patient with schwannoma of the brachial plexus. Material and methods: The clinical record was reviewed at the Institute of Breast Diseases, FUCAM, A.C. Case presentation: 77-year-old female, with palpable right axillary nodule self-detection, with mammography and non-FUCAM ultrasound on 10.30.2018 BIRADS 4a. He comes to the institute for axillary tumor, imaging studies are requested that report BIRADS 2, so an ultrasound-guided biopsy is performed, with a report of spindle cell neoplasia, a revision of the lamellae is carried out by two pathologists and a joint session is taken of excisional biopsy of right axillary nodule. With pathological report of 04.04.2019: schwannoma of 5 × 3 centimeters, totally resected. Conclusions: Brachial plexus tumors are infrequent, we cannot rule out primary breast tumor or any metastasis at the beginning. Knight reported series of 234 schwannomas between 1984 and 2004, of which 94 (40%) arose from the brachial plexus, used MRI as the imaging method of first choice, however ultrasound may suffice as long as it is accompanied by a mammogram should be confirmed by pathology to rule out malignant injury. All authors suggest that proper treatment is excision and preserving nerve and vascular function. It should not be forgotten that in the event of an axillary tumor, a malignant etiology must always be ruled out.REFERENCES
