Primary intracranial endodermal sinus tumors, which have been regarded as a rare histologic subtype, usually arise in the pineal and suprasellar regions and are often associated with components of other germ cell tumors. We report an extremely rare case of pure primary endodermal sinus tumor found
A rare case of yolk sac tumor in the cerebellar vermis is reported. A 2-year-old boy developed headaches, vomiting, and an unsteady gait. Later a tumor was demonstrated in the medial part of the cerebellum by gadolinium-enhanced magnetic resonance imaging (MRI). The tumor was totally removed, and
The nongerminomatous germ cell tumor occurring in the fourth ventricle is extremely rare. A 9-year-old boy presented with symptoms of obvious headache, projectile vomiting, diplopia and motor weakness. MRI scanning revealed lesions occupying the fourth ventricle, with dual-lateral ventricle
Several clinical trials have demonstrated that cisplatin-based chemotherapy for primary intracranial germ-cell tumors is effective as a neoadjuvant chemotherapy. In this report, we describe a 6-year-old boy, Down syndrome and Hirschsprung's disease with intracranial pure yolk sac tumor treated by
A case, a 18-year-old male, of an endodermal sinus tumor (yolk sac tumor) in the fourth ventricle, was reported. The patient had a month history of headache, vomiting and gait disturbance prior to the hospitalization, when he admitted to our service he was in lethargic condition with left cerebellar
A case of primary intracranial yolk sac tumor, the first known case growing in the frontal lobe, is compared with similar cases of suprasellar region. The case, 18-year-old female, suffered from headache, vomiting and visual disturbance for one month prior to the hospitalization. Plain CT scan
The primary intracranial endodermal sinus tumor (EST) is regarded as a rare histological subtype that is often associated with components of other germ cell tumors, and there are no reports on the onset of intracranial ESTs after growth hormone (GH) replacement therapy. The authors report an
Yolk sac tumor (YST) is a rare malignant germ cell tumor and typically occurs in gonads. It is extremely rare in the brain, especially in the fourth ventricle.This study reported the case of a 3-year-old boy with intermittent vomiting for 11 days and then Endodermal sinus tumors are rare malignant germ cell tumors that usually originate from the gonads and are rarely observed extragonadally. Pure primary endodermal sinus tumors of the cerebellar hemisphere are extremely rare and patients diagnosed with the disease often have a poor prognosis. The
A 17-year-old male patient presented to the clinic with a headache, nausea, and vomiting. Magnetic resonance imaging demonstrated a fat-containing and -enhancing heterogeneous tumor in the third ventricle, and fat droplets within the ventricles and the subarachnoid space. Obstructive hydrocephalus
OBJECTIVE
To investigate the clinicopathological characteristics, diagnosis, treatment and prognosis of gastric hepatoid adenocarcinoma(HAS).
METHODS
Retrospective analysis of clinicopathological data of 24 cases with gastric HAS diagnosed by surgery and pathology in Chinese PLA General Hospital
Two schedules of cis-dichlorodiammineplatinum(II) (cis-platinum) were evaluated for therapeutic efficacy and toxicity in children with malignant diseases resistant to standard therapy. Initially, cis-platinum was given as a rapid iv bolus injection at a dose of 15 mg/m2/day for 5 days every 3 weeks.
OBJECTIVE
Our objective was to evaluate the incidence and behavior of ovarian tumors in our population.
METHODS
Between 1984 and 1994, all clinical charts with the diagnosis of ovarian tumors were reviewed retrospectively. Of 158 tumors in females below 14 years of age, 7 were located in the ovary
Germ cell tumors, which constitute approximately 3-5% of tumors of the central nervous system (CNS), can be subdivided into germinomas, embryonal carcinomas, yolk sac tumors, choriocarcinomas, teratomas and mixed germ cell tumors. The diagnosis of intracranial germ cell tumor is based on the
A 7-year-old boy was admitted to Hokkaido University Hospital complaining of headache and vomiting. On admission he was slightly confused and presented Parinaud's sign. CT scan revealed abnormal high density mass with contrast enhancement effect at the pineal region and obstructive hydrocephalus.
