a SurePath™, staining Papanicolaou, lens 10x. Clinically: Follow-up of oral lichen planus. Cell-rich thin-layer preparation, mature squamous epithelia, individual nucleus less keratinized plaques, with tendency to hypereosinophilia, partly also amphophilia of the cytoplasm, individual hydrophilic swollen nuclei. Diagnosis: Malignant cells not present. b SurePath™, staining Papanicolaou, lens 40×. Clinically: Follow-up of oral lichen planus. Central a cell with partly eosinophilic, partly basophilic cytoplasm (amphophilia), nuclei of the two basophilic cells below are slightly enlarged with coarse chromatin as an expression of degenerative changes. Diagnosis: Malignant cells not present
