The immunohistochemical study of TrkA and β-catenin in this study showed that the distribution of these two markers in tumor tissue is similar, that is, the cells with abnormal expression of β-catenin in the “whorled epithelium” showed strong positive TrkA expression, and the palisade epithelium cells with normal membrane expression of β-catenin showed weak to moderate positive expression of TrkA. Here, NTRK1 is linked to neoplasm.
