Answer

Tumor markers, such as squamous cell carcinoma (SCC) antigen, are useful for identifying the presence of SCC arising from mature cystic teratoma (MCT), but no set cut-off level has been established. Choi et al reported elevated SCC antigen levels ranging from 1.5 ng/mL in International Federation of Gynecology and Obstetrics (FIGO) stage Ia tumors to 11.3 ng/mL in stage IIIc in four patients with confirmed SCC arising from MCT.
