The yolk sac tumor (YST) is the second most common subtype of OGCTs and has an aggressive phenotype. Their rarity in postmenopausal women has the potential to cause initial diagnostic uncertainty and lead to delayed or sub-optimal treatment. In this article, we report two cases. The first case is a 67-year-old woman with a pure YST and the second refers to a 59-year-old patient with YST with neuroendocrine differentiation. We also review and summarise the current literature. Discussion: YSTs in older women, either in association with ovarian epithelial tumors or without an identifiable epithelial precursor, are a challenging clinical situation. The disease is aggressive and the outcome remains poor. Thirty-seven cases, including the two reported in this article, have been described in the literature to date. 12/ 37 described patients with malignant OGCTs died within 8 months of diagnosis. Conclusion: Ovarian cancer with a YST component in postmenopausal women has an aggressive behaviour and adjuvant platinum-based chemotherapy should be considered.}, issn = {0250-7005}, URL = {https://ar.iiarjournals.org/content/35/12/6713}, eprint = {https://ar.iiarjournals.org/content/35/12/6713.full.pdf}, journal = {Anticancer Research} }
