C79.6

Clinical Information

• A tumor in the ovary caused by the spread of stomach cancer.

• Metastatic signet-ring cell carcinoma to the ovary. The primary site is the gastrointestinal tract or breast.

• Mucocellular carcinoma of the ovary, usually metastatic from the gastrointestinal tract, characterized by areas of mucoid degeneration and the presence of signet-ring-like cells. It accounts for 30%-40% of metastatic cancers to the ovaries and possibly 1%-2% of all malignant ovarian tumors. The lesions may not be discovered until the primary disease is advanced, and most patients die of their disease within a year. In some cases, a primary tumor is not found. from Dorland, 27th ed; holland et al., cancer medicine, 3d ed, p1685)

• The spread of the cancer to the ovary. This may be from a primary ovarian cancer involving the opposite ovary, or from a cancer at a distant site.
