Epithelial Cells:

Epithelial cells are round, cuboidal, or polygonal and tend to adhere tightly to each other and exfoliate in clusters or sheets.
They have a sharp cytoplasmic outline and exfoliate in moderate numbers.
Cells with more than one nucleus are uncommon..
Inflammatory reactions are cytologic responses in which inflammatory cells--neutrophils, eosinophils, lymphocytes, monocytes or macrophages--are the predominant cells seen.
Inflammatory reactions may be further classified as neutrophilic, mixed, macrophagic or granulomatous..
Malignant epithelial cells usually demonstrate cytologic criteria of malignancy particularly as they become more aggressive or advanced.
However, some carcinomas (e.g. the rare perianal carcinomas) do not always show features of malignancy but behave in a malignant fashion.
Epithelial cells generally have the following features:
( c) Intercellular “ windows ” The cytological features of mesothelial cells reveal sheets and loosely formed clusters of intermediate-sized cells with large centrally located nuclei, vesicular chromatin, small prominent nucleoli, dense cytoplasm, and intercellular “windows.” .
Interpretation of cytologic material may include:
Virally infected epithelial cells found in urine
