MUC16 and neoplasm: Given the mixed solid and cystic appearance of the ovarian mass, tumor markers were obtained, including lactate dehydrogenase (LDH), cancer antigen 125 (CA-125), carbohydrate antigen (CA 19-9), carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), human epididymis protein (HE4), inhibin B, and inhibin A. All tumor markers were reported to be within normal limits except for inhibin B, which resulted at 205 pg/m/L (Table 1).
