Introduction: One of the most feared complications of childhood cancer treatment is second malignant neoplasms (SMNs). This study evaluates the incidence, risk factors and outcomes of SMNs in a tertiary paediatric oncology centre in Singapore. Materials and Methods: A retrospective review was conducted on patients diagnosed with childhood cancer under age 21 and treated at the National University Hospital, Singapore, from January 1990 to 15 April 2012. Case records of patients with SMNs were reviewed. Results: We identified 1124 cases of childhood cancers with a median follow-up of 3...

Atypical teratoid/rhabdoid tumor (AT/RT) is a highly malignant central nervous system neoplasm usually diagnosed in young children, although it can occur in adults. Prognosis for AT/RT is poor, with a median survival of 10 - 11 months. We report a rare case of adult sellar and suprasellar AT/RT in a 36-year-old female patient. She was treated with multi-modalities including surgery, chemotherapy and radiation. She markedly improved following treatment with no recurrence in 3 years follow-up. To our knowledge, this is the 11th case of an adult-onset AT/RT in the sellar or suprasellar region with favorable long-term outcome...

Central nervous system (CNS) tumors represent the second most prevalent group of cancers in children and adolescents, yet account for the majority of childhood cancer-related deaths and considerable morbidity among survivors, due to high-intensity non-selective standard therapies delivered to immature nervous system structures undergoing development. These tumors arise at different ages -not infrequently very early in life-, in different locations and cellular contexts, have varied cell types of origin, and have heterogeneous responses to the "classic" current therapeutic approaches...

The clinical presentation and imaging studies of central nervous system tuberculosis are often indistinguishable from those of patients with malignant neoplasms or metastatic disease. Biopsies may be necessary to distinguish tuberculomas from other intracranial lesions such as pyogenic abscesses or necrotic tumors.

Dentatorubral-pallidoluysian atrophy (DRPLA), one of the polyglutamine diseases, has not been reported in combination with ganglioglioma (GG). Herein, we report an autopsy case of a 72-year-old man with DRPLA with a small GG component harboring neurofibrillary tangles (NFTs) and polyglutamine aggregates. NFTs, cytoplasmic accumulations of hyper-phosphorylated tau, are mainly observed in Alzheimer's disease (AD) and other tau-associated neurodegenerative disorders. NFTs can also be present in normal aging, and are occasionally observed in low-grade central nervous system (CNS) neoplasms such as GG...

BACKGROUND: Pilocytic astrocytomas (PAs) are the most common pediatric central nervous system neoplasms. In the majority of cases these tumors are benign and receive favorable prognosis following gross total surgical resection. In patients with progressive or symptomatic tumors, aggressive surgical resection is generally not feasible, thus radiation or chemotherapy are accepted initial or adjuvant interventions. Due to serious long-lasting side-effects, radiation is limited in young children; therefore, chemotherapy is widely practiced as an adjuvant treatment for these patients...

BACKGROUND: We analyzed the UNOS database to better define the risk of transmission of CNS tumors from donors to adult recipients of thoracic organs. METHODS: Data were procured from the Standard Transplant Analysis and Research dataset files. Donors with CNS tumors were identified, and recipients from these donors comprised the study group (Group I). The remaining recipients of organs from donors who did not have CNS tumors formed the control group (Group II). Incidence of recipient CNS tumors, donor related malignancies, and overall survival was calculated and compared in addition to multivariable logistic regression...

BACKGROUND: Meningeal melanomatosis is an extra-axial well-encapsulated malignant tumour with diffuse meningeal growth and dark coloration (due to high melanin contents), while meningeal melanocytoma is the focalized benign variant. Melanocytic lesions may be secondary to melanoma or be histologically benign, however, their diffuse nature makes them impossible to cure. Melanocytosis is a diffuse tumour that can form solitary extra-axial tumours, which invades the parenchyma and presents signs of malignancy with increased mitosis and Ki67, observed in 1 to 6% of immunopathological exams...

Objective A novel autoimmune CNS disorder with glial fibrillary acidic protein (GFAP)-IgG as biomarker was recently characterized. Here, 102 patients with GFAP-IgG positivity are described. Methods The 102 included patients had: 1) serum, CSF or both that yielded a characteristic astrocytic pattern of mouse tissue immunostaining; 2) confirmation of IgG reactive with specific GFAP isoforms (α, ε, or κ) by cell-based assays, and 3) clinical data available. Control specimens (865) were evaluated by tissue (542) and cell-based (323) assays...

Surgical resection is not the standard of care for primary central nervous system lymphoma (PCNSL), as historical studies have demonstrated unfavorable complication rates and limited benefits. Some recent studies suggest that resection may provide a therapeutic benefit, yet the safety of these procedures has not been systematically investigated in the setting of modern neurosurgery. We examined the safety of surgical resection for PCNSL. We retrospectively analyzed all patients with PCNSL treated at Columbia University Medical Center between 2000 and 2015 to assess complications rates following biopsy or resection using the Glioma Outcomes Project system...

Neoplastic CNS lesions are a common cause of focal epilepsy refractory to anticonvulsant treatment, i.e. long-term epilepsy-associated tumors (LEATs). Epileptogenic tumors encompass a variety of intriguing lesions, e.g. dysembryoplastic neuroepithelial tumors or gangliogliomas, which differ from more common CNS neoplasms in their clinical context as well as on histopathology. Long-term epilepsy-associated tumor classification is a rapidly evolving issue in surgical neuropathology, with new entities still being elucidated...

About one-half of all Burkitt lymphoma (BL) patients are younger than 40 years, and one-third belong to the adolescent and young adult (AYA) subset, defined by an age between 15 and 25-40 years, based on selection criteria used in different reports. BL is an aggressive B-cell neoplasm displaying highly characteristic clinico-diagnostic features, the biologic hallmark of which is a translocation involving immunoglobulin and c-MYC genes. It presents as sporadic, endemic, or epidemic disease. Endemicity is pathogenetically linked to an imbalance of the immune system which occurs in African children infected by malaria parasites and Epstein-Barr virus, while the epidemic form strictly follows the pattern of infection by HIV...

BACKGROUND: Childhood cancer survivors can experience learning problems resulting in lower-than-expected attained education as adults. It is unclear whether learning problems manifest already during adolescence. METHODS: We analysed nationwide Danish registries on school grades for Danish children during 2001-2014. Applying a matched design we compared grades of childhood cancer survivors to children without cancer at ninth grade. We estimated grade differences by subject and its correlation to cancer site and age at diagnosis...

Pituitary adenomas are benign tumors representing approximately 15-20% of intracranial neoplasms. There have been few reports of metaplastic osseous transformation and about 60 cases of neuronal metaplasia in pituitary adenoma but adipose metaplasia has not been previously described in the English literature. Here we report a case of pituitary adenoma with metaplastic adipose tissue in a 58-year-old male patient. Histologically this case fulfilled the criteria of a non-functioning pituitary adenoma, and moreover a central area of adipose tissue, made by mature adipocytes, and many tumor cells, containing fat droplet were evident...

Tissue microarrays (TMAs) represent a useful technique for the simultaneous phenotyping of large sample numbers and are particularly suitable for histopathologic tumor research. In this study, TMAs were used to evaluate semiquantitatively the expression of multiple antigens in various canine central nervous system (CNS) neoplasms and to identify markers with potential discriminative diagnostic relevance. Ninety-seven canine CNS neoplasms, previously diagnosed on hematoxylin and eosin sections according to the World Health Organization classification, were investigated on TMAs, with each tumor consisting of 2 cylindrical samples from the center and the periphery of the neoplasm...

Ovarian mature cystic teratoma (OMCT) is an ovarian benign neoplasm with excellent prognosis presenting components of the three germinal layers. However, transformation into a malignant neoplasm is a rare event (so-called somatic transformation). In most of the cases, the malignant component expresses as epidermoid carcinoma, but occasionally central nervous system tumors occur. Some of the previously reported tumors are astrocytoma, glioblastoma, and ependymoma. Somatic transformation of OMCT into an oligodendroglioma is exceptional...

Bertram Richter, Lakshmi Harinath, Cunfeng Pu, Kristen Stabingas
Metastatic spread of a systemic neoplasm to a central nervous system malignancy is a rare but well-documented phenomenon. Over 100 case reports of tumor-to-tumor spread involving the central nervous system have been described since the first report in 1930. Overwhelmingly, intracranial meningioma represents the most common recipient tumor, while breast and lung are the first and second most common donor malignancies, respectively. The propensity for meningiomas to harbor metastatic lesions has been attributed to cell-to-cell adhesion molecules, favorable metabolic environment as well as hormonal and mechanical factors...

OBJECTIVE: To describe the anesthetic considerations in patients undergoing laser interstitial thermal therapy (LITT) for neurosurgical procedures. BACKGROUND: LITT for neurosurgical procedures is being increasingly used in a variety of central nervous system diseases. Several studies have demonstrated promising results including a shorter hospital stay. Given the rising trend for the use of LITT, anesthesiologists need to be familiar with the anesthetic considerations to provide care for patients undergoing these types of procedures...

Filariasis, an endemic zoonosis in the Southeast Asia region, has been reported to affect various organs as well as the central nervous system (CNS). Inflammatory reactions mimicking those from neoplastic lesions clinically and radiologically have been reported in the breast and urinary bladder. To date, a CNS manifestation of filarial infestation has been reported in the form of meningoencephalitis. The authors here present an interesting case of a young man presenting in status epilepticus, which on radiological evaluation appeared to be a glioma...
