Tissue descriptors, also tissue characteristics, are things to think about when describing tissue to someone else.
Architecture/arrangement
- Gland forming.
- Palisading.
- Rosettes.
- Sheets.
- Nests.
- Cords.
- Epithelial specific.
- Stratified.
- Pseudostratified.
Borders of the cell
- Distinct.
- Indistinct.
- Spacing between cells (e.g. intercellular bridges).
Cytology
- Size - relative to RBC.
- Variability.
- NC ratio.
- Morphology.
- Epithelioid.
- Spindle.
- Columnar.
- Cuboidal.
- Nucleus.
- Shape.
- Stratification.
- Basal.
- Peripheral.
- Central.
- Multinucleation.
- Nucleoli.
- Number.
- Size.
- Chromatin.
- Inclusions.
- Consistency.
- Bland.
- Clearing.
- Stippled (salt 'n pepper).
- Cytoplasm.
- Colour.
- Consistency.
- Inclusions.
Other
- Vessels.
- Necrosis.
- Hemorrhage.
- Mitoses.
- Atypical mitoses.
- Inflammatory cells.
Simplified classification
- Arrangement - sheets, glands, nests, mixed population.
- Morphology - spindle, epithelioid, polygonal.
- Borders - distinct, indistinct, spaces.
- Cytoplasm - colour, other.
- DNA (nucleus) - number, location, size, nucleoli.
