Abstract | BACKGROUND: Currently, no specific immunohistochemical markers are available to differentiate primary mucinous epithelial ovarian cancer (MOC) from adenocarcinomas originating at other sites that have metastasised to the ovary, which may have an impact on patient management and prognosis. AIM: METHODS: RESULTS: Total cytoplasmic galectin 4 expression was relatively consistent between the different carcinomas. Membranous meprin alpha expression was significantly lower in MOCs compared with gastrointestinal carcinomas. Moreover, meprin alpha expression showed greater discrimination between the ovarian and gastrointestinal carcinomas than the cytokeratins CK7 and CK20, the current standard immunohistochemical markers used to determine the tissue origin of mucinous carcinomas involving the ovaries. CONCLUSIONS:
