Ovarian teratomas are the most common germ cell tumors and are classified as mature, immature and malignant.Mature cystic teratomas, also called dermoid cysts, are the most common germ cell tumour, accounting for upto 70% of benign ovarian masses in the reproductive years and 20% in postmenopausal women.Immature ovarian teratoma affects primarily younger patients and mature cystic teratomas seen in reproductive age groups. This case report provides a brief summary of the clinicopathological features of the ovarian teratomas such as, the immature teratoma which being a rare tumour was diagnosed in a 15 year old adolescent girl, managed surgically by laparotomy followed by chemotherapy, and the other case of a benign mature cystic teratoma in an elderly 52 year old postmenopausal woman, managed surgically although benign cystic teratomas are rare in the postmenopausal age group.
