There was no disruption on the external surface of the tumor (Figure 1).
Pathologic aspects of the ovarian intestinal-type mucinous carcinoma at low power view. Note the presence of residual bone tissue (arrow) (a). At a high power view, the glands are lined by columnar and goblet cells with moderate atypia and brisk mitotic activity (b).

Moderate to severe atypia and brisk mitotic activity were noted (Figures 2). Immediately adjacent to the malignant glandular component, residual teratomatous bone tissue was observed (Figures 2).

By immunohistochemistry, as we have previously described, the tumoral cells were positive for CK7, CK20, CDX2, PAX8, P53 (diffuse (diffuse/mutated staining), SATB2 and negative for WT1, ER, PR, p16 (Figure 3).
