Pathological results. a Dystrophic arteries and a large number of inflammatory cells, mainly including lymphocyte infiltrations, were observed in the portal area (hematoxylin and eosin (H&E) staining, magnification 100×). b Eosinophil infiltrations were seen in the tumor area (H&E staining, magnification 200×). c H&E staining revealed malignant epidermoid cells and mucus-producing cells with intracytoplasmic mucin. The tumor cells infiltrated into the stroma with occasional keratinization (magnification 200×). d Alcian blue stain-positive material highlights the mucin in mucin-producing cells (magnification 200×)
