case_images: (a): Right abdomen: ovary replaced by yellow-brown granular parenchyma, resembling or simulating testicular parenchyma. (b): Left abdomen: ovary with yellow-brown granular nodular areas.

case_images: Likewise, the left abdomen comprised a congestive fallopian tube and ovary with yellow-brown granular nodules similar to the tumour on the right side (Figure 1).
case_images: Right abdomen. (a): Congestive fallopian tube. (b): Ovary with proliferation of nests of different sizes, separated by a variable amount of fibromatous stroma. (c): Nests comprising two cell populations: germ cells in the central portion (*), and sex cord cells along the periphery (**).

case_images: Meanwhile, the sex cord cells presented with scant cytoplasm; small nucleus; and inconspicuous nucleolus (Figures 2 and 3).
case_images: Immunohistochemistry: the germ cells were positive for PLAP and OCT4 while the sex cord and Leydig/luteinised cells were positive for inhibin. In contrast, the germ cells as well as the sex cord cells were negative for calretinin.
