PURPOSE: IgG4-related disease is a systemic inflammatory disease characterized by infiltration of IgG4-positive plasma cells into multiple organs, including the pituitary gland. Autoimmunity is thought to be involved in the pathogenesis of IgG4-related disease. The diagnosis of IgG4-related hypophysitis (IgG4-RH) is difficult because its clinical features, such as pituitary swelling and hypopituitarism, are similar to those of other pituitary diseases, including lymphocytic hypophysitis and sellar/suprasellar tumors...

Intracranial germ cell tumor is sometimes associated with Down syndrome; however, no optimal treatment has been developed due to the high risk of recurrence and treatment-related mortality. Here, we report on a patient with an intracranial germinoma in the bilateral basal ganglia. The patient received 3 courses of ifosfamide-cisplatin-etoposide in combination with whole-brain irradiation (24 Gy), with no serious complications. The patient is alive and disease free 16 months after the initial diagnosis. This regimen is a feasible treatment for intracranial germ cell tumor associated with Down syndrome, although careful attention must be paid to the increased risk for severe infection...

A 27-year-old woman presented with anorexia, weight loss and psychiatric symptoms for the past 4 years. She did not have history of headache, visual disturbances or symptoms of raised intracranial pressure. She was sarcopenic with body mass index of 10.16 kg/m(2)Her systemic examination was normal except for temporal hemianopia suggesting a sellar/suprasellar lesion. Hormonal evaluation revealed pan-hypopituitarism with central diabetes insipidus. Subsequent neuroimaging revealed sellar-suprasellar mass lesion with intense contrast enhancement and leptomeningeal metastases...

We present a pediatric case of neurohypophyseal germinoma with a perifocal inflammatory reaction (PIR) with volume fluctuation caused by diagnostic radiation-induced regression (DRIR). On-target biopsy failed to confirm the histology because PIR hardly contained any germinoma cells. DRIR-related fluctuation of the tumor volume disguised germinoma as inflammation. We analyzed the cerebrospinal fluid (CSF) and detected a high level of placental alkaline phosphatase (PLAP), which demonstrated the neurohypophyseal lesion to be germinoma and brought the patient from successful radiochemotherapy up to complete remission...

The authors describe a case of a purely primary extramedullary spinal germinoma in a young Chinese male. Primary spinal germinoma is extremely rare tumor. Currently, less than 30 histologically verified spinal germinoma cases have been reported previously, mostly involving Asian of Japanese descent. This 24-year-old male suffered from progressive low back pain radiating to both legs. Magnetic resonance imaging showed a well-demarcated, intradural extramedullary mass at the level of L2 and L3. The lesion was totally removed and was confirmed as a germinoma...

INTRODUCTION: Extragonadal germ cell tumours (EGCTs) are a heterogeneous group with distinct natural history and responses to treatment modalities. We sought to evaluate characteristics and survival outcomes in men with EGCTs. METHODS: We performed a retrospective analysis on a consecutive list of men diagnosed with EGCT in two Albertan cancer centres between 1990 and 2013. Demographic characteristics and outcomes, stratified by primary site, were evaluated. RESULTS: Sixty-nine cases were identified...

We present a very rare case of suprasellar germinoma that spontaneously regressed before endoscopic biopsy. An 8-year-old boy was admitted to our hospital due to headache, polydipsia, and polyuria. Neurological examination performed on admission revealed bitemporal hemianopia. Enhanced MRI demonstrated a homogeneously enhanced tumor mass in the suprasellar region obstructing the foramen of Monro. Tests for all serum tumor markers were negative. Plain X-ray and CT scan were performed once and twice, respectively, for seven days between admission and endoscopic biopsy...

Primary spinal cord germinomas are an extremely rare group of tumors, most commonly reported as single cases in young Japanese adults. They usually present as intramedullary lesions located in the thoracic and thoracolumbar spine. The importance of preoperative diagnosis lies in the fact that by using radiotherapy and chemotherapy, even without surgery, a good cure rate can be achieved in patients with spinal cord germinoma. However, these tumors demonstrate unspecific imaging characteristics and only some secrete tumor markers...

Whether bifocal germinomas (BFGs) synchronously presenting within the pineal region and the hypothalamo-neurohypophyseal axis (HNA) are primary germinomas of dual-origin remains to be elucidated. We analyzed MRI images and clinical features of 95 neurohypophyseal germinomas and 21 BFG patients and developed a tentative definition of the BFGs. We found dual-primary BFGs (true BFGs) do exist. The fundamental difference between primary and metastatic HNA germinomas was the direction of tumor growth. For a true BFG, the primary HNA tumor grew from the neurohypophysis toward the hypothalamus and almost invaded the whole pituitary stalk...

Dr Robert E. Scully, who recognized and defined gonadoblastoma (GB), used the term "dissecting gonadoblastoma" (DGB) to describe variants with either an infiltrative type or diffuse pattern instead of the usual small nested arrangement. These patterns have not been emphasized in the literature. To investigate the features of DGB we examined 50 GBs microscopically and performed immunohistochemistry (IHC) in some. DGB was found in 38 (76%) GBs and was represented by 3 patterns. The most frequent was solid/expansile (n=26), consisting of large coalescent nests of germ cells, often (92%) interrupted by fibrovascular septa, with usually minor numbers of sex cord cells...

A 19-year-old Caucasian male presented with complaints of headaches and syncope. Suspicion of hydrocephalus prompted computed tomography (CT) and magnetic resonance imaging (MRI), which revealed pineal and suprasellar prominences with diffuse, thick, nodular subependymal enhancement of the lateral and third ventricles. Based on imaging, the differential diagnosis consisted primarily of malignancy, such as lymphoma, with inflammatory and infectious etiologies not excluded. Cerebrospinal fluid (CSF) samples were non-specific, and neuroendoscopic tissue biopsy histologically confirmed the diagnosis of pure germinoma...

OBJECTIVE Human chorionic gonadotropin (HCG) can be detected in a certain population of patients with a germinoma, but the frequency of germinoma HCG secretion and the prognostic value of HCG in the CSF are unknown. METHODS The authors measured HCG levels in sera and CSF in patients with a histologically confirmed germinoma by using a highly sensitive assay known as an immune complex transfer enzyme immunoassay (EIA), which is more than 100 times as sensitive as the conventional method, and they analyzed the correlation between HCG levels and the prognoses of patients with a germinoma...

CNS germinomas represent a unique germ cell tumor entity characterized by undifferentiated tumor cells and a high response rate to current treatment protocols. Limited information is available on their underlying genomic, epigenetic and biological alterations. We performed a genome-wide analysis of genomic copy number alterations in 49 CNS germinomas by molecular inversion profiling. In addition, CpG dinucleotide methylation was studied by immunohistochemistry for methylated cytosine residues. Mutational analysis was performed by resequencing of candidate genes including KIT and RAS family members...
