NY-ESO-1 expression patterns in synovial sarcomas, malignant peripheral nerve sheath tumors, and dermatofibrosarcoma protuberans (40 × ): (a and b), strong and diffuse expression (2−3+, >50% of tumor cells) in synovial sarcomas (38/50) of biphasic (4)(a) and monophasic (46)(b) subtypes; (c), strong and diffuse expression (2−3+, >50% of tumor cells) in malignant peripheral nerve sheath tumors (1/34); and (d), moderate and diffuse expression (2+, >50% of tumor cells) in dermatofibrosarcoma protuberans (2/20).
