A cytopathologist may perform a Fine Needle Aspiration Cytology (FNAC) in the case of smaller infected sites such as lymph nodes only.
Following the diagnosis of the presence of the illness, the tissue samples are screened and examined under a microscope. To successfully treat lymphoma, it is vital to know what type of lymphoma is taking over the patients system. There are two types of lymphoma; in Hodgkin’s lymphoma, the lymphoma tumors invade the lymphatic system, overall weakening the sufferer. Hodgkin’s lymphoma is singled out by an even spread of infected cells (lymphocytes) over the body’s lymph nodes. It spreads from lymph node to the next, forming a gross and maybe a fatal cycle, rather similar to that of the plague, which is painful and unbearable for the victim. Hodgkin’s lymphoma is diagnosed by the appearance of Reed-Sternberg cells (different giant cells originally derived from B lymphocytes), seen under light microscopy of biopsies or NFAC’s.
The other type of lymphoma is Non-Hodgkin’s lymphoma. It causes swelling of the infected lymph nodes, and its onset maybe aggressive (fast), or indolent (slow/gradual). Non-Hodgkin’s lymphoma may occur at any age, and cause obsolete swellings about the body. Collection of fluid due to the diseased lymphatic system causes most of the swellings (with the exception
Cellular/ Cyto pathology (basically means study of cells) is the branch of medicine which deals with the diagnosis of diseases. This practice was founded/ invented by Rudolf Virchow in 1858. As the name suggests, cells are primarily used to diagnose illnesses. The cells are obtained via biopsies or Fine Needle Aspiration Cytology – involves the sucking of cells from the diseased tissue by using a very fine needle/ syringe. Smears may also be used (such as the Pap smear – to diagnose cervical diseases), but only in complicated cases. These methods of extracting body cells for ...

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.
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.
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
Neutrophil infiltration can also be appreciated in submucosa and muscularis externa. Diagram also shows aggregates of lymphoid follicles which can be appreciated by the purple colour they have taken up after staining. H&E staining have stained an organism in the second
