Endoscopic (video) demonstration of hookworm infestation of the stomach.

Hookworm infestation is common in southern India. The adult worms normally reside in the duodenum, graze the intestinal mucosa with their large buccal cavities and ingest the intestinal epithelial cells and blood. Depending on the number of worms the infection may be either asymptomatic or can cause iron deficiency anaemia due to chronic blood loss.

Sertoli-leydig cell tumor of ovary- a diagnostic dilemma.

Sertoli Leydig Cell Tumours (SLCTs) are rare, unilateral, sex cord stromal tumours of ovary, which constitute less than 1% of all the ovarian neoplasms. These tumours can be functionally diverse and they may have heterologous elements. We aim to report a case of a 25-year- old woman who presented with suprapubic pain of 5 days duration, a unilateral adnexal mass, hypertestosteronism without virilization.

Cyclin D1 expression in multiple myeloma by immunohistochemistry: Case series of 14 patients and literature review.

Background: Cyclin D1 dysregulation is an early and unifying oncogenic event in patients of multiple myeloma (MM). This may be detected up to 30% cases by immunohistochemistry (IHC) and up to 40-50% cases by molecular studies. However, studies on the clinical significance of cyclin D1 dysregulation in MM have been inconclusive.

Hemophagocytic lymphohistiocytosis: critical reappraisal of a potentially under-recognized condition.

Hemophagocytic lymphohistiocytosis (HLH) is an uncommon, potentially life threatening, hyper inflammatory syndrome of diverse etiologies. Cardinal signs include prolonged fever, organomegaly, and persistent unexplained cytopenias. In spite of the well known diagnostic criteria put forth by HLH society, this continues to pose great diagnostic challenge in both pediatric and adult intensive care settings.

Isolated deletion of the long arm of chromosome 20 [del(20q12)] in myelodysplastic syndrome: a case report and literature review.

Isolated deletion of the long arm of chromosome 20 [del(20q12)] is a rare abnormality in patients with de novo myelodysplastic syndrome. It is characterised by refractory thrombocytopenia, minimal haematological dysplasia and a lower risk for progression to acute myeloid leukaemia. Its distinction from chronic autoimmune thrombocytopenia, although clinically and morphologically difficult, is critical.
