Figure 1: Characterization of the specimen. (a) Computed tomography findings. An approximately 6 cm × 3 cm × 2 cm well-defined mass with heterogeneous density, including myxoid and fat component was found, it was extending from the right spermatic cord to the right inguinal subcutaneous layer. (b and c) Gross findings. The resected specimen forms a well-encapsulated solid tumor originating from the spermatic cord (6 cm × 3 cm × 2 cm). On cut section, the tumor showed a whitish-yellow appearance with focal hemorrhage and without calcification. (d) H and E staining. Monophasic tumor with spindle cells in fascicular growth pattern is seen (light microscope, scale bar = 50 μm). (e) Immunohistochemistry. Tumor cells are partially positive for Ki67 (light microscope, scale bar = 50 μm). (f) Tumor cells comprise a normal fusion signal (consisting of a 650-kb spectrum red probe that lies distal from the SYT gene and a 1040-kb spectrum green probe that lies proximal to the SYT gene, arrow) and a pair of split signals (arrowheads), indicating a rearrangement involving the SYT gene (fluorescence in situ hybridization, scale bar = 10 μm).
