The recurrence of intracranial mature teratomas as germ cell tumors of different histological types is rarely reported. The authors describe the first case of the malignant transformation of an intracranial mature teratoma into a yolk sac tumor in a 16-year-old boy who presented with a 1-month history of anorexia and somnolence. Seven years prior to this presentation, the boy had undergone surgery for extirpation of a mature pineal teratoma. Computed tomography images obtained at his second… Expand
Pure germinoma occurring 11 years after total pineal mature teratoma removal: a case report and review of the literature
TLDR
This case demonstrated possible late occurrence of germinoma even after total removal of a mature teratoma had been achieved, and a long-term follow-up of 10 years or more should be planned for these patients. Expand
Extremely Late Recurrence 21 Years after Total Removal of Immature Teratoma: A Case Report and Literature Review
TLDR
The present unusual case of recurrent germinoma occurred 21 years after total resection of pineal IMT, demonstrating that disseminated IMT can be controlled for the long term without adjuvant therapy, but may recur as Germinoma. Expand
Sinonasal Pure Yolk Sac Tumor: A Case Report and Literature Review
TLDR
A case with sinonasal yolk sac tumor in a 1 year and 3 months old girl and the positive immunohistochemical staining of SALL4 and α-fetoprotein is reported. Expand
Growing teratoma syndrome in intracranial non-germinomatous germ cell tumors (iNGGCTs): a risk for secondary malignant transformation—a report of two cases
TLDR
Two pediatric patients whose intracranial NGGCTs progressed to growing teratomas during chemotherapy and later transformed to secondary malignant tumors after partial resection and radiation therapy (RT) are treated. Expand
Successful treatment of metastatic βHCG-secreting germ cell tumor occurring 3 years after total resection of a pineal mature teratoma
TLDR
A careful and long-term follow-up including scheduled tumor markers as well as surveillance MRI scans is required for patients with intracranial teratoma in an effort to detect and diagnose recurrent malignant disease, especially since multimodal therapy provides the potential for long- term cure.

YOLK SAC TUMOR – A RARE CLINICAL CASE YOLK SAC TUMOR –
Yolk sac tumor (aka. endodermal sinus tumor – EST) is a rare cancer of germ cell origin, characterized by high malignancy. Most cases of yolk sac tumor occur in childhood. The most common point ofExpand
Primary juxtaovarian yolk sac tumor concurrent with an ipsilateral ovarian mature teratoma in an adult woman: a rare association.
TLDR
This is the first report of an adult woman with a juxtaovarian YST concurrent with an ipsilateral ovarian mature teratoma, and it is suspected that the occurrence of the teratomas is earlier than the YST. Expand
Title Management of central nervous system teratoma
Central nervous system (CNS) teratomas are very rare neoplasms that contain tissues derived from all three germ cell layers (endoderm, mesoderm, and ectoderm). Patients with teratomas usually have aExpand
Management of central nervous system teratoma
TLDR
A retrospective review of 15 CNS teratomas treated over a 25 year period at the University of California, San Francisco describes the presentation, location, treatment, and adjuvant therapy for these patients, and highlights three unique cases that emphasize the diverse presentation and treatment of these rare tumors. Expand
Occurrence of metachronous pure germinomas long after treatment of a mixed germ cell tumor containing yolk sac tumor and germinoma.
TLDR
A rare case involving the occurrence of metachronous pure germinomas long after treatment of a mixed germ cell tumor (GCT) categorized as having a poor prognosis indicates the possibility of multicentric GCTs in the CNS. Expand

Retroperitoneal Mature Teratoma 15 Years after Initial Treatment of Testicular Mixed Germ Cell Tumor
TLDR
This represents the longest time interval reported in the literature for a mature teratoma following treatment of a testicular germ cell tumor. Expand
Cytogenetic analysis of a mature teratoma and a yolk sac tumor component of a late relapse of a disseminated testicular nonseminoma.
TLDR
Cytogenetic comparison of the different tumors shows that progression of primary testicular nonseminoma to residual mature teratoma and to a late-relapse lesion is accompanied by net loss of chromosomes. Expand
Bilateral Metachronous Germinoma of the Basal Ganglia Occurring Long after Total Removal of a Mature Pineal Teratoma: Case Report
TLDR
It is thought that if primordial germ cell groups exist along the midline of the brain, more than two primordial Germ cell groups could give rise to metachronous neoplasms at different sites and with different histological types long after total removal of a mature pineal teratoma. Expand
A case of malignant teratoma developing from the septum pellucidum 7 years after removal of a mature teratoma in the pineal region.
TLDR
The case is characterized by the development of a second malignant tumor and by the long interval from complete resection of the primary tumor to the occurrence of the second tumor. Expand
Metachronous neurohypophyseal germinoma occurring 8 years after total resection of pineal mature teratoma.
TLDR
The second neurohypophyseal germinoma occurring 8 years after total resection of a pineal mature teratoma was considered to be a de novo metachronous neoplasm rather than a recurrence of the original mature Teratoma. Expand
Third ventricle germinoma after total removal of intrasellar teratoma. Case report.
TLDR
A unique case is presented of a third ventricle germinoma developing 3 years after total removal of an intrasellar teratoma, thought to have been transformed from multicenter germ cells present in the midline of the brain with different temporal development. Expand
Recurrent yolk sac tumor following resection of a neonatal immature gastric teratoma
TLDR
Recurrence of a yolk sac tumor following resection of a neonatal immature gastric teratoma is described, and a periodic follow-up check with alpha-fetoprotein level should be mandatory. Expand

TLDR
In this report, a premature female infant was delivered at 29 week's gestation with a large sacrococcygeal teratoma and died intraoperatively of cardiovascular complications related to the large vascular supply of the tumor but had a grossly complete resection of tumor. Expand
