A pathologist deals with the causes and nature of disease and contributes to diagnosis, prognosis, and treatment through knowledge gained by the laboratory application of the biologic, chemical, and physical sciences. A pathologist uses information gathered from the microscopic examination of tissue specimens, cells, and body fluids, and from clinical laboratory tests on body fluids and secreti...

The anatomic pathologist performs an important role in the diagnosis or exclusion of infectious diseases. The morphologic interpretation of biopsies and cytologic preparations allows for the definitive establishment or exclusion of a wide variety of diseases. Once the pathologist has determined that a disease is likely to be due to an infection and has characterized the inflammatory response, a...

Pseudoepitheliomatous hyperplasia (PEH), a neglected entity by oral pathologist possesses utmost importance in the field of research. Of all the investigative challenges, PEH, a reactive epithelial proliferation is seen secondary to lesions with infectious, inflammatory, reactive, and degenerative origin. Small sized samples, incomplete excision, improper orientation, and dense inflammatory cha...

Laboratory reports should be signed to indicate to the clinician that someone in the laboratory accepts a responsibility for the content of the report. Failure to sign is likely to produce a loss ofconfidence in the laboratory. In any case, laboratory reports should be subjected to some form of check before issue and the signature should be the evidence that such a check has been carried out. A...

Transthoracic needle biopsy (TNB) of pulmonary nodules requires the skills of two specialists: (1) the radiologist and (2) the pathologist. From the radiologist’s perspective, the goal is very simple: to obtain a sufficient amount of material through the needle to allow the pathologist to make a diagnosis with a minimum of complications to the patient. Similarly, the goal of the pathologist is ...

Telecytologic diagnosis of cervical-vaginal smears is potentially useful because it could allow more efficient use of cytopathologist resources and expertise. A pathologist in one location could, in principle, review cytotechnologists' findings using a video display hundreds or thousands of miles away. Currently, bandwidth restrictions limit practical implementation of such a system to review o...

For a long time, the pathologist has mainly been dedicated to morphological diagnosis, including macroscopic and microscopic examination of organs tissues. Moreover, interaction between cli...
