An intact interface was seen between the mass and adjacent structures suggesting an absence of invasion and cytology revealed SPN (Figures 2, 3, and 4).
High power image shows cells with round to oval nuclei with fine chromatin and inconspicuous nucleoli and some with characteristic nuclear grooves.

An intact interface was seen between the mass and adjacent structures suggesting an absence of invasion and cytology revealed SPN (Figures 2, 3, and 4).
Immunohistochemical staining shows nuclear positivity for beta-catenin in the tumor cells, which is characteristic of SPN.
