CONTEXT Extragastrointestinal stromal tumors arising in the pancreas are extremely rare. To date, only eight cases have been reported in the literature. CASE REPORT A 42-year-old female patient presented with gradually increasing abdominal pain of 6-month duration. Computerized tomography scan of the abdomen demonstrated a solid cystic mass in the body(More)
Pleomorphic xanthoastrocytomas are indolent, astrocytic tumors usually located in the superficial cerebral cortex. They have not been described as occurring in the pineal region. We describe a patient with an astrocytic tumor arising in the pineal region that fulfilled all of the morphologic and immunohistochemical criteria of a pleomorphic(More)
BACKGROUND Cranio-spinal axis teratomas are rare. This subset is interesting because symptoms can be varied, depending on the location. Histopathology is diagnostic; most of the lesions are benign. Rarely, malignancy develops in any of the somatic components. AIMS To study the demographic, clinico-morphological and follow-up data of central nervous system(More)
Glioblastomas (GBMs) are the most common and lethal primary tumors of the central nervous system with high level of recurrence despite aggressive therapy. Tumor-associated proteins/peptides may appear in the plasma of these patients as a result of disruption of the blood-brain barrier in them, raising the scope for development of plasma-based tests for(More)
BACKGROUND Meningiomas represent about 30% of primary adult central nervous system tumors. Though slow growing, they recur, causing significant morbidity and mortality. OBJECTIVE The objective of the following study is to grade meningiomas according to World Health Organization (WHO) 2007 criteria and to correlate the grade with degree of expression of(More)
CONTEXT With the continuing rise in the number of immunocompromised patients, the incidence of invasive mycoses has increased. Various studies have reported the trends of fungal infections in autopsies. Because of limitations in antemortem clinical diagnosis owing to lack of sensitive diagnostic tools, information regarding frequency and pathogenesis of(More)
Primary diffuse leptomeningeal gliomatosis (PDLG) is a rare condition, characterized by infiltration of the meninges by glial cells without evidence of the primary tumor in the brain or spinal cord parenchyma. Glioma arising primarily from the leptomeninges is extremely rare and often diagnosed only in post mortem examination and the diagnosis may be missed(More)
BACKGROUND Inflammatory myopathy (IM) as a manifestation of paraneoplastic syndrome has been well-documented. However, the prevalence of malignancies reported varies across the studies. There are very few studies reported from Asia, only one from India. AIM The aim of this analysis was to study the prevalence of malignancy in biopsy-proven cases of IM in(More)
Plasma cell leukemia (PCL) is a rare and aggressive variant of plasma cell dyscrasia. They occur de novo (primary) or as a late manifestation of multiple myeloma (secondary). Patients present with anemia, thrombocytopenia, renal failure, organomegaly and extramedullary manifestations. We are presenting this series as it is the second largest series from(More)
Dear Editor, Neurenteric cysts are rare benign endodermal lesions of the central nervous system like the Rathke cleft and colloid cysts. Intracranial neurenteric cysts are rare, with less than 100 cases reported in literature, most of which are found in the posterior fossa. We discuss a rare case of an extradural neurenteric cyst with supratentorial and(More)
