Magnetic resonance imaging of the lesion: A/Coronal T2 weighted B/Axial
T1 weighted images showing a large well-defined multiloculated irregular
cystic lesion of 211 x 199 x 106 mm arising from the right ovary with
hyperintense septal fat.

The abdomino-pelvic magnetic resonance imaging (MRI) showed a large multiloculated irregular cystic lesion of 211x199 x 106 mm arising from the right ovary with thickened wall and some endocystic vegetations, seat of irregular and thickened partitions as well as vegetations (Figure 1).
Macroscopic findings of the specimen. The tumor is arising from the broad
ligament. The mass is composed of a yellowish lobulated glistening
gelatinous cut-surface.

The cross-sections of the tumor showed large number of nodular areas showing a gelatinous cut surface (Figure 2).
Histological findings of low-grade myxoid liposarcoma. H&E, original
magnification x40. The tumor is composed of an abundant myxoid matrix,
lymphangioma-like cystic spaces with component of mature fat tissue.

Tumor cells had indistinct cytoplasmic borders and oval, stellate-shaped nuclei (Figure 3).

On immunohistochemical staining, tumor cells were positive for S-100 (Figure 4), and negative for CK, CK7, EMA, and HMB45.
