Surgical Pathology: A specimen is ordered as a "surgical pathology" specimen when a core biopsy has been obtained.Even if slides are made and a cytojar is used along with the core biopsy, it is still ordered as a surgical pathology. Examples of surgical pathology specimens include lung, liver, and GI biopsies collected in formalin, with a needle wash in a cytojar and smears made.
Cytology: A specimen is ordered as a "cytology" when no core biopsy has been obtained. This is when the aspirate is used to make cytology smears and placed in the cytojar ONLY. Examples of cytology specimens include fine needle aspirations of thyroid, pancreas, cysts etc.
