Abnormal nuclear localization of beta catenin generally indicates the presence of a mutation in WNT/APC pathway. Such mutations are characteristic of abdominal fibromatoses. High levels of nuclear beta catenin expression can also be seen in endometrial stromal tumors, synovial sarcomas, solitary fibrous tumors, and a subset of colorectal and endometrial adenocarcinoma.
