Core Tip

Core Tip: Primary ovarian mucinous carcinoma is a rare histologic subtype of epithelial ovarian carcinoma and exhibits considerable morphologic overlap with secondary tumour. Because of the histologic similarity between primary ovarian mucinous carcinoma and metastatic gastrointestinal carcinoma, it has been hypothesized that ovarian mucinous carcinomas might respond better to non-gynecologic regimens. Here, we report an initially misdiagnosed case of primary ovarian mucinous carcinoma by considering clinical characteristics, imaging, and genetic tests. The patient received a chemotherapy regimen based on the histologic characteristics rather than the tumour origin. This achieved satisfactory therapeutic efficacy.
