The specimens have been stained with hematoxylin and eosin (H&E) which is the commonest stain used in light microscopy because it stains various structures quite simply(Ovalle et al, 2013, p.g.479). The diagrams show signs of inflammation. Mucosa is damaged and crypts can be…
The eggs of E. vermicularis which can be seen in the picture are roughly 25 x 60 um in size. The organism has a thin shell and one of the sides is compressed. The eggs and shell of organism have taken up the pink dye which makes them recognizable.
The presence of E. vermicularis in the appendix can give the symptoms of acute appendicitis (Wiebe, 1991, p.g. 336). The appendix is a vestigial organ present in the human body. The inflammation of this organ leads to appendicitis. Acute appendicitis is one of most common diseases that lead to inflammation of the gastrointestinal tract. Acute appendicitis is caused due to the obstruction of the lumen, diminished blood supply, pinworm infections caused by Enterobius vermicularis, bacterial infections or due to ischemic damage to mucosal lining of organ (Becker and Hofler, 2002, pg.777). The best described pathogenesis of appendicitis is an obstruction in the appendiceal lumen. The obstruction can be due to lodging of foreign body, lymphoid hyperplasia, fecolith or tumours. The pathogenesis of appendicitis can be understood by the course that the disease takes. In the primary stage, there is obstruction of the lumen which causes accumulation of fluid leading to elevation of intraluminal pressure and lastly resulting in distension of lumina. Suppurative appendicitis occurs due to increased intraluminal pressure which increases the capillary perfusion leading to venous obstruction and hence causing arterial compromise. These crucial events lead to ischemia of the mucosal surface and allow bacterial infestation. As the disease progresses, it causes mural infection which is characterized by oedematous thickening of the appendicular walls. When observed grossly the appendix appears hyperaemic and enlarged. If this progressive condition is not managed surgically it may lead to perforation and gangrene. Gangrenous appendicitis may present as friable serosa with green or black discoloration. If ...

In general, lymphoma is represented by a solid cancer cells or tumors found in the lymph node. Depending on the stage and the type of cancer cell, people who are diagnosed with lymphoma can be treated with either chemotherapy, radiotherapy, or bone marrow transplant (Parham, 2005, p.
ve of the diseased organ. Recently guidelines suggest an adequate biopsy specimen to be 20- 25 mm long and consisting of 11 complete portal tracts (Cholongitas et al, 2006); this might be less when it comes to focal lesions, such as in this particular patient.
Glycogen is preserved in the slides using the alcoholic preservation methods. The use of formalin solution will help to reduce the shrinkage and polarization of the tissue. Periodic Acid Schiff (PAS) stain is the most commonly used stain to identify the structures containing large amounts of glycogen, glycoprotein, mucin, proteoglycan and other basement membranes.
Liver slides for glycogen and ileum slides for mucin staining (using Alcian Blue) were prepared as well with use of diastase digestion. Introduction The Periodic Acid Schiff (PAS) stain is a stain routinely employed in several cellular pathology laboratories.
Since this case involves a human being and thus human materials, which is a scarce situation. Surgical materials or rather tissues are the best source of human tissue due to the ability to remove the normal tissue together with the affected/diseased tissues.
Lymphoma can be diagnosed through an excisional biopsy, by obtaining a minute sample of tissue from the affected body site (maybe the lymph nodes in the neck, armpits or groin, or even the stomach, skin or brain).
The Periodic Acid Schiff (PAS) stain is a stain routinely employed in several cellular pathology laboratories. Several tissue components can be demonstrated by this stain. It is an important diagnostic tool in most
In the first section of the tissue examination, Haematoxylin and Eosin stain is used to give a good visibility of the cells and nucleus of the tissue and their activity state. Haematoxylin is a dye that is
