Negative for tumour cells—SurePath, staining Papanicolaou, lens 40×. Clinically most probably oral lichen planus (OLP). The background is completely clear. Bacterial flora can still be appreciated clinging to the cell surfaces. A group of five mature squamous cells with reactive changes: cytoplasmic hypereosinophilia and amphophilia, and megalocytosis of the central cell with corresponding mild nuclear enlargement. Small perinuclear halos of the two cells in the left field. All nuclei are round to ovoid with smooth contours and finely granular, evenly dispersed chromatin.
