Histopathology involves detailed microscopic study of diseased tissues after use of special techniques for preparation of specimens.
Histopathology is often used in clinical medicine. Typically it involves examining a biopsy often of a sample or specimen surgically removed from a patient. A pathologist detailed study. Depending on his or her specialist training and main area of work, the pathologist may be more accurately referred to as a histopathologist because medical specialists who study and interpret diseased tissues in microscopic detail are histopathologists. However, in the cases of some pathologists, examination of diseased tissues in microscopic detail may only be a relatively minor part of their overall professional responsibilities so the term “histopathologist” may not always be use.
