Architectural Features: 3D = 3D Overlapping Clusters; T = Tubular Formations; P = Papillary Formations; SC = Cellular Discohesion/Single Cells

Cytoplasmic Quantity: S = Scant; M = Moderate

⁺= present

⁻= absent

NA = not assessable

Nuclear Size Variation: M = monomorphic; P = moderately pleomorphic (2x size variation)

Nuclear Shape: R = round/oval; F = fusiform

Chromatin Pattern (when assessable): C = coarse; V = vesicular

Nuclear Contours: G = grooves/indentations; M = molding

Nucleoli – Number: - = not seen; 1 = single; >1 = multiple

Nucleoli – Size (when present): I = inconspicuous; P = prominent

Nucleoli - Location (when present): C = central; P = peripheral
