The tumor shows infiltration into the tendons and aponeuroses.
The tumor is highly infiltrative and organized in a haphazard arrangement into small compact nests and fascicles of uniform neoplastic cells dissecting along the dense fibrous connective tissue of tendons, fascia, and aponeuroses.
Clear cell sarcoma of tendons and aponeuroses is characterized by the reciprocal chromosome translocation, t(12;22)(q13;q12), which can be detected by conventional chromosome analysis (Figure 5), FISH, and reverse transcriptase polymerase chain reaction.
