BACKGROUND: Pure mucinous @entity0 is a rare entity characterized by the production of variable amounts of @entity3558 comprising 1% to 6% of @entity0 . Some @entity3079 have shown expression of intestinal differentiation markers such as @entity5091 . This study examines the expression of intestinal differentiation markers in this type of @entity0 . RESULTS: Twenty-two cases of pure mucinous @entity0 were assessed. Immunochemistry was performed for @entity3546 , @entity6628 and @entity5091 . All cases were positive for @entity3546 . @entity5091 positivity was observed in all cases; 63. 6% were 3 plus positive. All cases were negative for @entity6628 . CONCLUSIONS: These results suggest that mucinous @entity0 express some markers of intestinal differentiation, such as @entity5091 and @entity3546 ; however, future studies with a larger series of cases and using molecular techniques that help affirm these results are needed.
