This is a dysgerminoma, an uncommon but malignant ovarian neoplasm. The histopathology with undifferentiated germ cells, large vesicular cells with clear cytoplasm, well-defined boundaries, and centrally placed regular nuclei are often described as “fried eggs.” On pathology, the yellow arrow shows the bisected Fallopian tube; the green arrow shows the neoplasm, and the white arrow shows a hemorrhagic component (unusual).
