Assessment of β-catenin, LEF-1 and P16. a: β-catenin showed normal type (membranous positive) in the carcinomatous component and abnormal type (cytoplasmic and/or nuclear positive) in the sarcomatous component (× 20). b: LEF-1 expression is obviously found in nuclei of sarcomatous components but very few in carcinomatous components (× 10). c: P16 yielded positive results in the cytoplasm and nuclei of both components (× 10)
