Benign central neurocytoma (CN) is a rare neuronal tumour of the central nervous system recognised since the early eighties. More than 300 articles have been published in the literature, mostly comprising of case reports and short series from individual specialties. These tumours, though normally benign, are more often likely to recur after surgery than(More)
Glioblastoma multiforme (GBM) occurs rarely in children. Relatively few studies have been performed on molecular properties of pediatric GBMs. Our objective in this study was to evaluate the genetic alterations in pediatric GBM (age < or = 18 years) with special reference to p53, p16, and p27 protein expression, alterations of the epidermal growth factor(More)
OBJECTIVES The goals of this study were: (1) to obtain basic information about the effects of long-term use of mobile phones on cytological makeup of the hippocampus in rat brains (2) to evaluate the effects on antioxidant status, and (3) to evaluate the effects on cognitive behavior particularly on learning and memory. METHODS Rats (age 30 days, 120 ± 5(More)
Relatively few studies have been performed on molecular properties of pediatric glioblastoma multiforme (GBM). Methylation of DNA repair gene O6-methylguanine-DNA methyltransferase (MGMT) promoter region has been associated with favorable prognosis and prolonged survival in adult GBM patients treated with temozolomide (TMZ). We explored the frequency of(More)
BACKGROUND O6-methylguanine methyltransferase (MGMT) promoter methylation in adult glioblastomas (glioblastoma multiforme) is considered a promising molecular alteration, predictive of better response to temozolomide therapy and longer overall survival. OBJECTIVE To look at the frequency of MGMT methylation in glial tumors of all grades and types, and(More)
AIMS Various molecular markers have been used for diagnosis, management and prognostication of gliomas. Neurocytomas are close morphological mimics of oligodendrogliomas. While combined 1p/19q deletion has been used as a molecular signature of oligodendroglial tumours, it has also been variably reported to occur in neurocytomas, especially those in(More)
BACKGROUND Malignant melanoma is the foremost cause of metastasis to the breast from extramammary solid neoplasm. However primary melanoma of the breast is a distinct rarity. Primary melanoma involves the skin and less commonly the glandular parenchyma of the breast. METHOD We herein describe a case of primary amelanotic melanoma of the breast parenchyma(More)
Apart from the skin and choroid plexus, primary malignant melanoma is rare at the other sites and lacks organized documentation. Here, we have tried to enumerate the primary malignant melanomas at various atypical sites, supported by literature review. Seventeen cases were identified from our records of the past 5 years, which had detailed clinical work-up(More)
CONTEXT Idiopathic inflammatory myopathies (IMs) have been postulated to be of autoimmune origin on the basis of expression of markers like MHC-1 and other mediators involved in autoimmunity such as cell adhesion molecules. AIMS The present study aims to analyze the expression of cell adhesion molecules ICAM-1 and VCAM-1 and their respective ligands LFA-1(More)
Craniocerebral maduromycetoma is extremely rare; only 2 cases have been reported so far. The authors report a case of maduromycetoma in a 17-year-old girl from a rural background in the state of Rajasthan, India, with involvement of the right parietal cortex, overlying bone, and subcutaneous tissue. The mass was totally excised, along with the involved dura(More)
