肿瘤细胞为实性片状及条索状浸润性生长，以胞浆透亮的非典型中间型细胞为主，幷见较多粘液腺腔，未见明显表皮样细胞，符合粘液表皮样癌【 Low grade: mucinous and intermediate cells with bland nuclei form glandular spaces】。（High grade: solid and infiltrative growth pattern of atypical epidermoid and intermediate cells with cytoplasmic clearing and small number of mucinous cells; <20% intracystic component）。鉴别诊断：透明细胞癌、腺鳞癌及腺泡细胞癌等。
（粘液表皮样癌分级系统：AFIP point system:
● 2 points if <20% intracystic component
● 2 points if necrosis
● 2 points if neural invasion
● 3 points if 4+ mitotic figures/10 HPF
● 4 points if anaplasia
● Low grade if total score is 0-4 points, intermediate grade if 5-6 points, high grade if 7+ points）
