What are the advantages of cytology for sampling inflammation in animals?

Sampling is quick, safe, and inexpensive. Cells can often be safely retrieved from lesions near vulnerable structures in conscious animals, making anesthesia and surgical biopsy unnecessary. Sampling demands little equipment or skill. Results can be quickly available. Signup and view all the answers

What are the limitations of cytology in the diagnosis of neoplasia?

In the diagnosis of neoplasia, cytology has limitations such as false negatives and false positives. False negatives may occur due to poor exfoliation of a neoplasm, failure to sample tumor tissue, or extensive necrosis/inflammation present. False positives may occur due to dysplasia, which can mimic neoplasia, or inflammatory lesions where all cells in the healing response reflect somewhat neoplastic lesions.

What information can histopathology provide that cytology cannot?

Histopathology provides information on tissue architecture, adequacy of excision, invasion, and is often the next diagnostic procedure. It can provide information on tissue architecture, which is often not preserved in cytology samples. Signup and view all the answers

What is the difference between fine needle sample (FNS) and biopsy as diagnostic procedures?

FNS (Fine Needle Sample) is a minimally invasive procedure that requires minimal patient prep and restraint, can be done in conscious animals, and provides quick microscopic review. However, it does not preserve tissue architecture. Biopsy, on the other hand, is a more invasive procedure that requires more patient prep, restraint, and anesthesia. It involves fixing the tissue in formalin, preserving tissue architecture, and is often more conclusive than FNS. Signup and view all the answers

What are the characteristics of epithelial cells in cytology samples?

Epithelial cells in cytology samples are high yield, associated with one another, form rafts, sheets, acini, and have a cuboidal, columnar, cobblestone-like appearance. They have distinct cytoplasmic borders. Signup and view all the answers
