Ultrasound examination indicated that there was an uneven echo mass of 14.2 cm x 9.3 cm x 12.8 cm in the pelvic cavity, the boundary was clear, attenuation was observed in the rear, and no blood flow signal was observed (Figure 1).
Histological finding at original magnification x20. (1) (A) Shows the sebaceous gland and appendages, suggesting mature cystic teratoma (MCT); (2) (B) shows mixed two components (both squamous cell carcinoma and sarcoma); (3) (C,D) indicates that both CK and vimentin are positive, suggesting bidirectional tumor differentiation.
