Primary intraosseous lytic meningiomas are rare tumors, with only 16 cases described in the literature. We present a case in which CT and MR imaging with contrast agent helped diagnose preoperatively an enlarging skull mass as a primary intraosseous lytic meningioma in a 70-year-old woman. Radiographic findings revealed a lytic mass centered on the coronal(More)
Strongyloides stercoralis, a nematode parasite, is endemic in tropical and subtropical regions. Infection usually remains asymptomatic, but in immunocompromised hosts hyperinfection and dissemination can occur, which has a high mortality. Early detection of S. stercoralis may alter the fatal course of infection. We present our experience of five patients(More)
Adenoid cystic carcinoma (ACC) constitutes about 4% of salivary epithelial tumors and is the second common malignant epithelial salivary gland tumor involving both the major and minor salivary glands. High grade transformation in ACC is a recently recognized entity with only a few cases reported in literature. We report the first case of ACC with high grade(More)
BACKGROUND The term gastrointestinal stromal tumors (GIST) is used to refer to those mesenchymal neoplasms of the gastrointestinal tract (GIT) which express CD117, a c-kit proto-oncogene protein. AIMS To study the cytological features of GIST and extra-gastrointestinal stromal tumors (EGIST), to correlate them with histology and to determine cytological(More)
Glomerular podocyte molecules are involved in the pathogenesis of congenital nephrotic syndrome. However, their role in primary nephrotic syndrome is not clear. This study investigated the expression of nephrin, podocin and synaptopodin in primary nephrotic syndrome. Eighty-seven patients with primary nephrotic syndrome including minimal change disease(More)
AIM Leprosy classically presents with cutaneous and neural involvement. Rheumatological manifestations are frequent, although often under-recognized. At times, these may present to a rheumatology clinic prior to the diagnosis of leprosy. Herein, we present our experience with patients referred with various rheumatological disorders who were subsequently(More)
BACKGROUND Granulomatous tubulointerstitial nephritis (GIN) is common due to infections, drugs or sarcoidosis. However, the cause is often difficult to establish and the studies are limited. We studied the etiology of GIN and compared the clinical and histological features and outcome in different etiologies at a tertiary care center in North India. (More)
Alveolar soft part sarcoma is a rare tumor affecting mainly adolescent and young children. It presents as a slowly growing tumor and is usually overlooked due to lack of symptoms. Early metastasis is a characteristic feature of this tumor and, in a good number of cases, metastasis to the lung or brain is the first manifestation of the disease. In this(More)
Collapsing glomerulopathy (CG) is a distinct clinicopathological entity characterized by high levels of nephrotic range proteinuria, rapidly progressive renal failure, marked parenchymal injury, and poor response to present therapeutic regimens. Growing awareness has led to the identification of associated conditions other than human immunodeficiency virus(More)
Immunopathogenesis of Campylobacter jejuni-associated Guillain–Barré syndrome (GBS) is not yet well established probably due to lack of experimental model. Therefore, we studied the Th1/Th2 immune response and pathological changes in C. jejuni-induced chicken model for GBS. C. jejuni (5 × 109 CFU/ml) and placebo were fed to 30 chickens each. Stools of all(More)
