malignant peripheral nerve-sheath tumor (mpnst) is a high-grade malignant tumor of ecto-mesenchymal origin comprising approximately 10% of soft-tissue sarcomas. they tend to occur associated with neurofibromatosis or sporadically. here we report a mpnst at an extremely rare location and behavior causing disappearance of the entire kidney. patient evaluation included clinical, biochemical and ra...

The incidence of intrahepatic cholangiocarcinoma has been increasing in the last few decades. Interestingly over this period, the incidence of extrahepatic cholangiocarcinoma remained stable. However, the proportion of patients with early stage, small or localized tumors remained the same. This reflects a true increase in the incidence without a corresponding significant gain in our ability to ...

OBJECTIVE To determine the diagnostic yield of EBUS guided TBB performed in routine practice with flexible bronchoscopy and under moderate sedation in ambulatory and hospitalized patients. METHODS Bronchoscopy was performed under standard conditions in ambulatory and hospitalised patients. Bronchoscopically invisible peripheral pulmonary lesions were located with 20 MHZ-EBUS-probe and transbr...

Objective To evaluate the value of multiple guided technologies based on radial probe endobronchial ultrasound (R-EBUS) in the application of the diagnosis of solitary pulmonary peripheral lesions (PPLs). Methods Analysis of diagnostic yield in 4 groups patients with different combined multiple guided technologies based on R-EBUS, 94 patients with 94 solitary PPLs from Mar, 2013 to Nov, 2014 in...

anticoagulation drugs are frequently used to prevent deep vein thrombosis in high-risk patients. subcutaneous low molecular weight heparin (lmwh) is increasingly used in both hospitalized patients and outpatient settings. this necessitates familiarity of both health care providers and patients with such treatment and vigilance on possible complications. here we present a case of hematoma of rec...

palisaded encapsulated (solitary circumscribed) neuromas (pens) are relatively common intraoral neurogenic tumors, which occur most frequently on the hard palate. herein, we describe the clinicopathological characteristics of a palisaded encapsulated neuroma of the tongue. this tumor was an exophytic sessile mass measuring 0.3× 0.4 cm with rubbery consistency on the anterior one-third of the do...

malignant peripheral nerve sheath tumor (mpnst) is a rare malignant tumor that develops either from a preexisting neurofibroma or de novo. the cell of origin is believed to be the schwann cell and possibly other nerve sheath cells. in this report, we describe a rare case of mpnst that arise from the socket of second left maxillary molar that has been already extracted in a young man. he was ref...

In this experiment the effect of inoculation with Azospirillum on the flag leaf and spike rachis anatomical features and also on grain yield and grain weight was investigated for the first time in bread and durum wheats during 2015-2016 growing season under semi-arid condition. The crop yield increased due to the inoculation with Azospirillum with a maximum yield increase of about 8.0 per cent ...
