Figure 3 Pathological results of the neoplasms. A: HE-stained image (200×) showing monotonous neoplasms formed by spindle-shaped cells; B and C: Immunohistochemical analysis demonstrated that the neoplasms expressed TLE (B, 100×) and vimentin CD99 (C, 200×); D: Genetic analysis confirmed the presence of SYT-SSX translocation using a SYT dual color break apart probe-based FISH test. About 50% of the tumor cells had abnormal yellow, red, and green break signals.
