title: [Synovial cyst of chest wall; report of a case].
abstract: A 55-year-old male taxi driver visited our hospital because of a left dorsal tumor. The tumor was palpated at the inferior angle of the left scapula with tenderness. Computed tomography (CT) revealed a homogeneous 5-cm mass with capsule between the latissimus dorsi muscle and rib. T2-weighted magnetic resonance imaging( MRI) demonstrated the tumor with high intensity. The latissimus dorsi muscle was divided and separated off from the tumor and the lower layer;then, an applied wound retractor (Alexis) was placed under the lower layer of the latissimus dorsi muscle and the operative field was developed. Next, the anterior serratus and greater rhomboid muscles were separated off from the tumor and the lower layer, the Alexis was placed under the lower layer of those muscles. All muscles were preserved and the tumor was removed. The tumor was 56×32 mm in size. The histological diagnosis was synovial cyst.
