Malignant ovarian germ cell tumours are uncommon and it occurs mainly in adolescent age group1, and very rarely in post-menopausal period. Clear cell carcinoma ovary occurs in older age groups [1]. They occur either in pure form or maybe associated with other types of germ cell neoplasm. Yolk sac tumours rarely coexists with epithelial carcinoma, and is rare in post- menopausal women. Here we report a case of 60-year-old post-menopausal women with bilateral ovarian malignancy which contained components of clear cell carcinoma and yolk sac tumour. Such a combination of tumours are rare [2].
