The Anatomic Pathology Division of the Pathology Department offers various services, including the Autopsy Service, Surgical Pathology, Cytopathology and Neuropathology analysis. This group has a collection of paraffin embedded tissues that can be accessed for immunohistochemical analysis. A centralized Histology Laboratory, which provides routine processing, sectioning and staining of body tissues, as well as a wide variety of special stains and advanced immunohistochemical procedures are available on a charge basis. On-site technicians will section requested tissues and perform immunohistochemical labeling on a charge basis. Optionally, sections can be mounted on slides and the investigator may process immunohistochemical labeling. This section prepares 250,000 slides a year for pathologic examination. In the Cytopathology Laboratory, cellular morphology studies are performed on a variety of specimens, including gynecologic smears, body fluids and fine needle aspirations. The Cytopathology Laboratory examines 8,000 gynecologic specimens and 2,500 non-gynecologic specimens annually. About 300 fine needle aspirations are performed each year.
