Synovial sarcoma of the brachial plexus: a rare tumor in a r
Synovial sarcoma arising from the brachial plexus is rare. The treatment is multimodal with complete excision (often challenging owing to the proximity of the neurovascular structures) and adjuvant therapy.

Synovial cell sarcomas are usually seen in a juxta-articular location. However, they occur rarely in the head and neck region. The present case has been reported in Journal of Medical Case Reports.

The authors present a rare case of brachial plexus synovial sarcoma in a 24-year old man treated successfully with surgical excision followed by radiotherapy.

The patient presented to the hospital with a progressively enlarging swelling that started on the left side of his neck and extended inferior to the clavicle increasing in size over a period of 6 months. On examination a 10 × 12 cm globular, firm, non-pulsatile and immobile swelling was palpable on the left side of his neck. Tinel’s sign was negative on percussion. The lateral border of swelling was felt in the apex of axilla; it had smooth lobulated borders. He did not have any motor or sensory deficits. However, the brachial, radial, and ulnar artery pulses were absent.

There was no locoregional lymphadenopathy and no metastasis. The clinical staging was stage 3 tumor (T3, N0, M0) according to the tumour, nodes and metastasis (TNM) classification.
