Mucinous tumors of the ovary are a diverse group of neoplasms with varying degrees of malignant potential. Metastatic colorectal cancer can occasionally present in the ovary, mimicking primary ovarian mucinous tumors on morphology. This report describes a case of metastatic mucinous carcinoma of the colon masquerading as a mucinous borderline tumor of the ovary on morphology, highlighting the diagnostic challenges and the importance of a multidisciplinary approach in such cases.
