Cytology of cells: ovoid, slightly irregular nuclei and minimal clear cytoplasm. There are single plasma cells in infiltrate. There is slight syringothropism of lymphocytes.  
IMMUNO: CD20+, CD43+, Bcl2+, CD23-/+ (some cells <5% and plasmacytes focally), CD10/Bcl 6-, CyclinD1-.  
Germinal centres of follicles: CD10+, Bcl6+, Bcl2-. Some with irregular contour, maybe colonized.  
PROPOSED DGN.: Cutaneous B marginal zone lymphoma. Very strong CD43+ and focal CD23 positivity?
