case_images: 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.
