On exploratory laparotomy, the mass was found to be a moderately differentiated adenocarcinoma of the sigmoid colon with metastasis to the left ovary.

Histology and tumor markers are currently the most useful tools available in making an accurate diagnosis.

However the possibility of a concurrent primary ovarian tumor must not be overlooked.
