Anatomical pathology

Anatomical pathology is the branch of pathology that looks at tissue
structure and biopsies; it is extensively used in tumor diagnosis.

The procedures used in anatomical pathology :

   * examination with the naked eye (this is important especially for large
     tissue fragments)
   * examination of stained sections on glass slides with a microscope (most
     commonly haematoxylin and eosin - a pink and blue stain)
   * examination with special stains for iron, organisms, calcium, elastic
     tissue, mucins etc
   * examination with immunoperoxidase and immunofluorescence stains -
     special antibody type stains especially useful in tumour pathology, in
     some inflammatory skin diseases and renal biopsies
   * Electron microscopy
   * Tissue cytogenetics
