Background: A combination of epithelial cells and lymphocytes results in a varied histomorphology of thymomas and consequent varied classification systems. Aim: To correlate the Marino and Muller-Hermelink (MMH) classification with the invasive behaviour of

conclusions our data showed that inhalation of diazinon during pregnancy increased the hepatocyte area and hepatocyte apoptosis while it decreased the sinusoid area of the fetal liver. materials and methods twenty-five pregnant balb/c mice (25 - 30 gr) were divided into five equal groups in the animal lab of baqiyatallah university of medical sciences, tehran, iran. the normal group was without...

BACKGROUND Leiomyosarcomas (LMS) and endometrial stromal sarcomas (ESS) may display overlapping histomorphology, which may challenge diagnostic accuracy. Since LMS and ESS have vastly different clinical behavior and adjuvant therapy recommendations, accurate diagnosis is critical. CASE We present the case of an 83-year-old female with postmenopausal bleeding who underwent total abdominal hyst...

Case report from a 12-years old russian girl with pulmonary alveolar microlithiasis. The diagnosis was confirmed by histologic examination from biopsy specimen of the lung. The differential diagnosis and the histomorphology are discussed.

Enhanced surface photooxidation property associated with the ZnS nanoparticles caused the reduction of dissolved oxygen content in water in a dose dependent manner, when ZnS nanoparticles of different sizes are exposed to the water in various concentrations. This property was more prominent for ZnS nanoparticles with smaller sizes. Mystus tengara, exposed to ZnS nanoparticles, responded to hypo...

Formalin fixation is a mainstay of modern histopathologic analysis, yet the practice is poorly standardized and a significant potential source of preanalytical errors. Concerns of workflow and turnaround time drive interest in developing shorter fixation protocols, but rapid protocols can lead to poor histomorphology or inadequate downstream assay results. Additionally, assays such as immunohis...

Intestinal Behçet’s Disease (BD) may manifests with several signs varying from superficial and deep ulcers to massive bleeding and colon perforation. Both mucosal ulcer and inflammation observed as a result of the affected small diameter vessels and ischemic damage findings due to the affected large diameter vessels are significantly associated with morbidity and mortality. In addition, differe...
