a SurePath™, staining Papanicolaou, lens 10x. Clinical: erosion of oral mucosa (mandible), condition after extraction 3 years ago, 1–2 packs of cigarettes daily. Cell-rich thin-layer preparation, mature squamous epithelia, some nucleusless keratinized plaques, plenty of fibrin and lysed blood in the background, individual squamous epithelia with shifted nucleus-plasma ratio and arranged in differently sized, partly two-, mostly three-dimensional clusters. Diagnosis: Malignant cells present. The cell picture corresponds to a keratinising squamous cell carcinoma. b SurePath™, staining Papanicolaou, lens 40x. Clinical: erosion of oral mucosa (mandible), condition after extraction 3 years ago, 1–2 packs of cigarettes daily. Fibrillary material in the background (tumor diathesis), small group of tumor cells with large, mostly deformed nuclei and some recognizable macronucleoli. Diagnosis: Malignant cells present. The cell picture corresponds to a keratinising squamous cell carcinoma
