The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions. [8]
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
Initial reports questioned whether this was a true medical disorder, or whether the inflammation was secondary to another condition, such as gastroesophageal reflux disease. The cause of lymphocytic esophagitis is unknown. The disease may cause different symptoms and be caused by different processes in childhood as compared to adulthood.
Histopathology of eosinophilic esophagitis, showing multiple intraepithelial eosinophils (bilobed cells with reddish cytoplasm on H&E stain), and edema seen as white clearings. Endoscopic mucosal biopsy remains the gold standard diagnostic test for EoE and is required to confirm the diagnosis. [8]
Gastritis is the inflammation of the lining of the stomach. [1] It may occur as a short episode or may be of a long duration. [1] There may be no symptoms but, when symptoms are present, the most common is upper abdominal pain (see dyspepsia). [1]
Hemosiderin deposition in the liver is a common feature of hemochromatosis and is the cause of liver failure in the disease. Selective iron deposition in the beta cells of pancreatic islets leads to diabetes [4] [2] due to the distribution of transferrin receptor on the beta cells of islets [3] and in the skin leads to hyperpigmentation.
Histopathology of a pulmonary artery with fat embolism (seen as multiple empty globular spaces on this H&E stain since its processing dissolves fat). There is a bone marrow fragment in the middle, and multiple single hematopoietic cells in the blood, being evidence of fracture as the source of the embolism.
H&E stain. In liver pathology , a ground glass hepatocyte , abbreviated GGH , is a liver parenchymal cell with a flat hazy and uniformly dull appearing cytoplasm on light microscopy . The cytoplasm's granular homogeneous eosinophilic staining is caused by the presence of HBsAg .
