Histopathology

Histopathology (compound of three Greek word's: ἱστός histos "tissue", πάθος pathos "disease-suffering", and -λογία -logia) refers to the microscopic examination of tissue in order to study the manifestations of disease. Specifically, in clinical medicine, histopathology refers to the examination of a biopsy or surgical specimen by a pathologist, after the specimen has been processed and histological sections have been placed onto glass slides. In contrast, cytopathology examines free cells or tissue fragments.
