CT scan of the abdomen and pelvis revealed a massive, solid, and clearly bordered formation with the dimensions 12 x 8 x 15 cm. The suspicious formation showed a connection to the right ovary that was hyperdense and had an inhomogeneous appearance. Some hypodense tissue within the tumour mass was identified as probably "fatty tissue."

Some hypodense tissue within the tumour mass was identified as probably "fatty tissue" (Figures 1(a) and 1(b)).
After an additional examination with intravenous contrast medium the tumour mass showed a raised vascularization within the tumour.

After an additional examination with intravenous contrast medium the tumour mass showed a raised vascularization within the tumor (Figures 2(a) and 2(b)).
Uniform tumor cells arranged in nests, separated by delicate fibrous stroma rich in lymphocytes (x5; H&E stain).

Histological examination revealed infiltrating islands of uniform tumor cells with ample clear cytoplasm with central or slightly excentric nuclei with a vesicular chromatin pattern and prominent nucleoli (Figures 3 and 5).
Medium-sized tumor cells with eosinophilic cytoplasm and central nuclei with vesicular chromatin (x10; H&E stain).

The tumor islands were separated by collagenous stroma densely infiltrated by lymphocytes (Figure 4).
Higher magnification showing focal prominent nucleoli of the tumor cells (x20; H&E stain).

Histological examination revealed infiltrating islands of uniform tumor cells with ample clear cytoplasm with central or slightly excentric nuclei with a vesicular chromatin pattern and prominent nucleoli (Figures 3 and 5).
Lymph node metastasis with area of the tumor cells partially replacing the lymph node structure (x2.5; H&E stain).
