![]() ![]() Electrocautry in parotid surgery causes oncocytic changes in acinar cell If electrocautry are used for coagulation can drive surface epithelium into the connective tissue thus producing a pseudocysts and loss of cytoplasmic and nuclear feature. Some of the commonly used surgical instrument for the biopsy can penetrate the specimen and it can cause voids or tears and compression of surface epithelium into the connective tissue. It can be avoided by using block injection technique or injecting well away from the site. Large amount of anesthetics solution injected into site can lead to hemorrhage, vacuolation of epithelium and it may separate the connective tissue from epithelium. These colored solution are used carefully and this should be mentioned clearly because it may interfere tissue processing and staining procedure. Sometime tincture iodine is used as decontaminant for biopsy site. Some commonly used reagents are Indian blue,alcian blue or alcian green ,silver nitrate. ![]() These types of artifact are produced before the tissue is being fixed.Some of the coloring agent is used for marking the biopsy site and for appropriate orientation of the specimen margins. Artifact can occurs at any stage, which can be classified as the following Presence of artifact can lead to inaccurate diagnosis.Hence,it is important to know and understand the commonly occurring artifact, so that we can avoid misdiagnosis. ![]() when it is present it may confuse with normal tissue or any pathological changes. Some artifact are easily distinguished and some are not. Available from: Īn artifact is defined as any structure or feature in the histological section, which is not normally present in the normal tissue, and it may come from outside sources. Histological section pathological embedding microtomyĭownload this article as: Copy the following to cite this article: It is therefore important to identify the common occurring artifacts during interpretation of oral biopsies. These artifacts may occur during surgical removal, fixation, processing, embedding, microtomy and staining procedures. Defects are common in this lengthy procedure and they are referred as Artifact.Accuracy of the histopathological diagnosis depends on eliminating or minimizing the artifact in histological section. processing of tissue specimen is a length procedure. Microscopic examination of histological section of the tissue does not always related to normal histology or pathology.

This JPEG image has been so highly compressed that it has too many unsightly compression artifacts, making it unsuitable for the cover of our magazine.Sudha Jimson, L. (computing) A perceptible distortion that appears in a digital image, audio or video file as a result of applying a lossy compression algorithm.An object made or shaped by some agent or intelligence, not necessarily of direct human origin.The spot on his lung turned out to be an artifact of the X-ray process. A structure or finding in an experiment or investigation that is not a true feature of the object under observation, but is a result of external action, the test arrangement, or an experimental error.* "The very act of looking at a naked model was an artifact of male supremacy" (Philip Weiss).Something viewed as a product of human conception or agency rather than an inherent element.(archaeology) An object, such as a tool, weapon or ornament, of archaeological or historical interest, especially such an object found at an archaeological excavation.An object made or shaped by human hand. ![]()
