Diffuse large B cell lymphoma (DLBCL), currently the most common type of non-Hodgkin lymphoma (NHL), is an aggressive B cell neoplasm that typically presents in older adults as a rapidly enlarging mass. The enlarging mass typically represents a lymph node, although extranodal disease can occur in a significant percentage (40%) of cases. The most common extranodal sites of involvement include th...

KHE: kaposiform hemangioendothelioma KMP: Kasabach-Merritt phenomenon INTRODUCTION Kaposiform hemangioendothelioma (KHE) was first described by Zuckerberg et al in 1992. KHE is defined as a rare, locally aggressive infiltrative vascular neoplasm that typically occurs during infancy and childhood. KHE generally originates on the skin as a distinctive cutaneous lesion with ill-defined borders, la...

BACKGROUND Scrotal schwannoma is a rare neoplasm and poses a diagnostic challenge to urologists. This article describes a rare case of ancient scrotal schwannoma and reviews the current modality of investigation and treatment of this tumour. CASE REPORT A 28 year old man presented with a 3-month history of an asymptomatic scrotal swelling. Ultrasonography and computer topography revealed an i...

AIM OF THE STUDY To analyse the incidence of appendiceal neuroendocrine neoplasms in appendectomy specimens and establish the epidemiological and histopathological features, treatment, and clinical course. MATERIAL AND METHODS Between 2004 and 2013, 975 patients who underwent appendectomy in Ankara Oncology Education and Research Hospital were retrospectively analysed. RESULTS Neuroendocrin...

fluid invasion from water-based drilling mud (wbdm) into the shale formations causes swelling,high pressure zone near the wellbore wall, and eventually wellbore instability problems duringdrilling operations. for the stability of the wellbore, physical plugging of nanoscale pore throats couldbe considered as a logical approach toward avoiding the fluid invasion into the shale formation. thispap...

Osteosarcoma (OS) is an aggressive malignant mesenchymal neoplasm amongst adolescents. The aim of the present study was to explore the various modes of action that miR-379 has on the proliferation, migration, and invasion of human OS cells. miR-379 achieves this by targetting eukaryotic initiation factor 4GII (EIF4G2). Human OS cell lines U2OS and MG-63 were selected and assigned into blank, mi...

BACKGROUND MUC5AC is a secretory mucin normally expressed in the surface muconous cells of stomach and bronchial tract. It has been known that MUC5AC de novo expression occurred in the invasive ductal carcinoma and pancreatic intraepithelial neoplasm with no detectable expression in normal pancreas, however, its function remains uncertain. Here, we report the impact of MUC5AC on the adhesive an...

The strategy for treating small borderline malignant pancreatic neoplasms--such as neuroendocrine tumor (NET) and solid pseudopapillary neoplasm (SPN)--is surgical resection. However, pancreatic resection of these lesions still causes significant morbidity. We evaluated the safety and efficacy of EUS-guided ethanol ablation to treat small solid pancreatic neoplasms. A total of 8 patients with s...

BACKGROUND/AIMS Intraductal papillary neoplasm of the bile duct (IPNB) represents a biliary papillary tumor mainly growing in the bile duct lumen resembling intraductal papillary mucin-producing neoplasm of the pancreas. However, its clinical spectrum and characteristics have not been fully evaluated. METHODOLOGY To define the clinicopathologic characteristics and prognosis of IPNB patients, ...

INTRODUCTION Thyroid angiosarcoma is a malignant neoplasm, which usually shows local aggressive behavior and associated with a high recurrence rate. It was originally described in the Alpine region and extremely rare in other parts of the world. CASE PRESENTATION An asymptomatic 61-year-old woman presented with a right lobe thyroid nodule with fine needle aspiration cytology indicating "suspi...
