A computed tomography (CT) scan of the abdomen showed 12.5x7.8x11.2 cm sized large heterogeneous pelvic mass invading sigmoid colon and uterus (Fig. 1).
The tumor was composed of solid sheets or aggregates of uniform cells with moredate or abundant eosinophilic cytoplasm, distinct cell borders, and centrally located nuclei with prominent nucleoli (H&E, x200).

Histologically, the tumor was composed of solid sheets or aggregates of uniform cells with moderate or abundant eosinophilic cytoplasm, distinct cell borders, and centrally located nuclei with prominent nucleoli (Fig. 2).
Immunohistochemistry for alpha-fetoprotein (AFP). The tumor cells are not immunoreactive for AFP (immunostain for AFP, x200).
