Immature Teratoma: Diagnosis and Management—A Review of the Literature

Abstract: An immature teratoma is a germinal malignant tumor composed of three germ cell layers, occurring more frequently in young women. It is the second most frequent among the malignant germinal tumors after dysgerminoma, and it is the only neoplasm with germ cells that are histologically graded. Even if we do not have a consensus regarding its therapeutical management, it has a good prognosis, with an excellent overall survival rate and good fertility preservation. More studies are needed regarding the necessity of… Show more

“…Little is known about the genetic and molecular etiopathogenesis of immature teratomas. It is known that DNA methylation levels in mature and immature teratomas are similar, but there are some aberrant methylation levels in immature teratomas [ 11 ]. In the present case, TFUS was initially performed, followed by a head CT, and then a head MRI was performed to further evaluate the condition.…”

“…The prognosis of immature teratoma is associated with the degree of tumor differentiation, i.e., those composed of undifferentiated embryonic tissues have a worse prognosis [ 12 , 13 ]. In immature teratomas, compared with mixed germ cell tumors, fewer genetic alterations were found [ 11 ]. In the case reported here, the tumor was shown to be aggressive, with a large mass effect, and therefore difficult to manage in a two-month-old infant.…”

“…Prognosis in cases of immature teratomas is influenced by the degree of differentiation, with more undifferentiated components potentially indicating a less favorable outcome. Timely and comprehensive surgical resection is often the primary treatment approach [ 4 ].…”

“…Sacrococcygeal teratoma (SCT) is proven effective in neonates with a female preponderance. Both developed and undeveloped parts are considered non-cancerous cells, and the possibility of metastasis is unknown [ 2 , 3 ]. Mostly hard and lobulated, undeveloped teratomas have several tiny cysts.…”

“…Observation of a variety of tumors can describe differentiation into nerves (neuroepithelial rosettes and immature glia), glands, and other structures found in mature cystic teratomas. Nearly one-third of immature teratomas express serum-fetoprotein [ 3 ]. Immature ovarian teratomas are usually found in girls up to their early 20s.…”
