Cytology

We use cytology to diagnose and determine treatment needs for a variety of conditions.  We collect cells, stain them and examine them microscopically.  Cytology slides may be sent to a pathologist for an opinion.



Conjunctival Scraping Cytology The first picture is from a cat with conjunctivitis.  A conjunctival scraping was completed. There are multiple cell types and bacteria.
 The second picture is from a Fine Needle Aspirate.  Fine Needle Aspirates (FNAs) can be done quickly and easily in the exam room.  Most pets do not require sedation.  We made a diagnosis of Mast Cell Tumor that was later confirmed and graded after the mass was excised and sent to the pathologist.  The ability to determine what a mass is before excising it gives us greater knowledge of how aggressive to be in surgery.  With benign masses, we can be conservative.  But, with tumors such as this Mast Cell Tumor, we needed to be aggressive with wide surgical margins.
 
 No Description
 No Description This is also from a FNA.  Many of the cells have a spindle shape.  Spindle cells arise from tissue such as nerves and connective tissue.
 These are fat cells, consistent with typical Lipoma.  Lipomas are benign tumors of fat.   No Description resized to 600 pixels wide
 No Description resized to 300 pixels wide This is a demodectic mite from a skin scraping. This is a common mite found in puppies and immunocompromised animals.
 Pleural fluid cytology.  A kitty with difficulty breathing and weakness developed fluid in his chest.  
  Broncho-alveolar lavage was completed on as a part of the work up for a coughing cat.  The kitty is now being treated successfully for asthma.
 This cytology from a fine needle aspirate of a lump was for a high grade malignant fibrous histiocytoma.  This was determined by the pathologist from a biopsy taken after the FNA.  
   This is an impression smear which is collected simply from squishing a microscope slide to a tissue.  This was from a foot which had an irregular mass on it on a young dog.  The lump was ultimately diagnosed as a papilloma.  This papilloma was a viral wart which eventually resided when the pup's immune system controlled it.
 This toe was swollen and bothering the dog.
The site was not responding to antibiotics.  A FNA was completed to determine if this  was a cancer or not. 
This was not a cancer and eventually resolved without surgery!
