Cytology
- Touch Imprints ("Impression
Smears")
- Rapid Dx of some
external lesions & excised
tissues (may be subsequently
examined by histopath)
- Yield fewer cells than scrapings
- Risk of only detecting
surface
inflammation/blood or
contaminants
- Rapid Dx of some
external lesions & excised
tissues (may be subsequently
examined by histopath)
- Scrapings
- Dx of some external lesion & excised tissue
- Collects more cells
than impression
smears
- Collects more cells

- Parasitology on
skin
- Scapel perpendicylar to
surface being scraped
- Blunt spatula for delicate
tissues (Ex. Conjunctiva)
- Blunt spatula for delicate

- Dx of some external lesion & excised tissue
- Fine Needle Aspirates (FNA)
- Cutaneous masses, Internal
masses & organs, lymph nodes, etc.
- Avoids superficial
contamination
- Collects samples from deep
