The frozen section diagnosis of the mass returned in favor of a squamous cell carcinoma arising in mature cystic teratoma without infiltration or rupture of the ovarian capsule (Figures 2 and 3).
High cell density tumor proliferation made up of anastomotic cord intercepted by monomorphic clusters with rounded nuclei or ovoid granular chromatin without mitotic activity; hematoxylin and eosin staining, x400.
