Growing tumor syndrome (GTS) occurs rarely in women with immature ovarian teratoma. Unlike many malignancies, it can be successfully treated chemotherapy and fertility-sparing surgery. Early diagnosis is crucial to avoid unnecessarily aggressive treatment.

Tumors of neuroepithelial origin are extremely rare in teratoma and tend to be derived from glial or primitive neuroectodermal cells. We describe a case of 2- month-old baby girl with an oligodendroglioma arising in an immature teratoma of the sacrococcygeal region. Histologically, the tumor was identical in appearance to low grade oligodendroglioma within the adult brain. Because immature tera...

Introduction: Teratomas are neoplastic tumors derived from totipotent germ cells containing a wide assortment of tissues originating from all three germ cell layers. Teratomas can be mature or immature depending on the presence of immature tissues; typically neuroepithelial tissue. Immature teratomas can be oncologically benign or malignant, and can be divided into three grades with increasingl...

Background: Ovarian immature teratoma is a very rare type of tumor associated with a high relapse rate and mortality. Correspondingly, early diagnosis is important for effective treatment. The goal of this study was to retrospectively analyze the ultrasound characteristics of 11 cases of immature teratomas. Materials and Methods: Between January 2002 and December 2010, 11 patients were diagnose...

teratomas that occur in the uterus are exceedingly rare. to the best of our knowledge there are only 22 cases of mature and immature teratomas of the uterus and cervix thus far reported in the literature. we report an unusual case of mature cystic teratoma of the uterine surface with well-differentiated adenocarcinoma of the endometrium and uterine leiomyoma along with a mature cystic teratoma ...

Background: Immature teratomas of the ovary represent less than 1% of all ovarian teratomas. Growing teratoma syndrome is an increase of tumor size containing a mature teratoma component, during or after chemotherapy for

The gastric teratoma is a rare tumor that usually presents as an abdominal mass, with or without features of gastric outlet obstruction. We report two cases of gastric teratoma; one - mature in a male neonate and another - ruptured immature gastric teratoma in a female neonate.
