Histopathology and Cytology

The Histopathology Laboratories provide a full range of anatomic pathology tests and services. Techniques include frozen section and fixed tissue light microscopy, immunohistochemical and immunofluorescent staining. Special areas of expertise include dermatopathology, gastrointestinal, breast, head, and neck, endocrine, renal, dermatopathology, neuropathology (including muscle and nerve) and ophthalmic pathology.

Cytology (also known as cytopathology) involves examining cells from bodily tissues or fluids to determine a diagnosis. Healthcare providers use cytology in many different areas of medicine, but cytology tests are most used to screen for or diagnose cancer.

There are two main kinds, or branches, of cytology: exfoliative cytology and intervention cytology.

  • Exfoliative cytology include: Gynecological samples: A Pap smear,
  • Gastrointestinal tract samples: during an endoscopy procedure for cytology testing.
  • Skin or mucus samples: scrape off cells from skin or mucous membranes, such as the inside of nose or mouth, for cytology testing.
  • Respiratory samples: can collect fluids such as spit and mucus (also called phlegm or sputum) that cough up for a respiratory cytology test.
  • Urinary samples: can collect a urine (pee) sample from you to use for a cytology test.
  • Discharge or secretion samples: If you experience abnormal bodily discharge, such as from eye, vagina or nipple,

Intervention cytology include:The most common type of intervention cytology is fine-needle aspiration (FNA)

  • Fluid-filled lumps (cysts) under your skin.
  • Solid lumps (nodules or masses) under your skin.
  • Your lymph nodes.
  • Your pericardial fluid, which is the fluid in the sac around your heart.
  • Your pleural fluid, which is in the space between your lung and the inside of your chest wall.
