Ovarian teratomas include mature cystic teratomas (dermoid cysts), immature teratomas, and monodermal teratomas (eg, struma ovarii, carcinoid tumors, neural tumors). As with epithelial ovarian cancers, it is a good idea to consult with a gynecologic oncologist for treating malignant germ cell tumors, especially because these are so uncommon. Mature cystic teratoma is usually asymptomatic. struma ovarii tumor. Mature cystic teratomas are encapsulated tumors with mature tissue or organ components. Teratomas may be cancerous or noncancerous, and they can affect people of all ages. 2a, b). Struma ovarii usually presents in the fifth and sixth decades of life and seldom before puberty [ 1 ].

Cystic teratoma appears as a large pelvic monocular cyst with a solid nodule named Rokitansky protuberance attached to a thin wall and protrudes in the cyst lumen. Although CT may play a useful role in diagnosing ovarian cystic lesions such as malignant ovarian tumor and mature cystic teratoma, it may be more often limited to characterization of the contents or nature of lesions 3. If the ovarian teratoma is large, a surgeon may remove a part or all of the ovary. Mature cystic teratoma is the most common germ cell neoplasm and, in some series, the most common ovarian neoplasm removed at surgery (7,8).

The other prognostic factors include tumour grade, growth pattern, capsular rupture and vascular invasion [6, 7].Age alone has been shown to be an independent predictor of survival in those with ovarian cancer [].The 2-year disease free survival for grade 1, grade 2 and grade 3 is 83%, Affects mostly young females < 20 years old. The prognosis of immature teratoma heavily depends on the FIGO stage. This type of teratoma is very rare, and in most cases, it is found in newborns.
