Cellular level | Cell: seen in longitudinal tissue plane rather than transverse/depth |
---|---|
 | Cellular morphology, expected histology |
 | Nuclear staining pattern- orientation, size, shape, limits |
 | Nucleolar staining morphological pattern, orientation |
Tissue Level | Cell-cell regularity |
 | Extracellular matrix- homogenous, heterogeneous |
 | Margin- discrete, blurred |
 | Underlying cells, micro-vessel density |
