A 65-year-old woman has a 12 cm unilateral ovarian mass with papillary projections, marked nuclear atypia, and stromal invasion exceeding 5 mm. Psammoma bodies are present. Which FIGO stage is this if confined to one ovary with intact capsule and no ascites?

• A Stage IIA
• B Stage IB
• C Stage IC
• D Stage IA ✓

Explanation

This is a serous cystadenocarcinoma (papillae, psammoma bodies, stromal invasion). Confined to one ovary with an intact capsule, no tumor on the surface, no malignant cells in ascites or washings is FIGO Stage IA. Stage IC requires capsular involvement, surface tumor, or positive washings. Stage IIA involves extension to the uterus or tubes.
