Seven cases of sinus piriform cancer have been studied in which a pharyngolaryngectomy was performed after a biopsy had confirmed the diagnosis. The macroscopic study of the tumors shows a clear predominance of exophytic forms besides their tendency to spread in the endolaryngeal structures in a submusous way. The microscopic study indicates that in all the cases epidermoid carcinoma were predominating those that moderate cellular differentiation. The surgical pieces were embedded in celloidin and sectioned both in the horizontal and frontal plane, afterwards being stained with hematoxylin and eosin.
对7例梨状窦癌进行了研究，这些病例在活检确诊后均接受了咽喉切除术。肿瘤的宏观研究显示，除了倾向于以黏膜下方式扩散至喉内结构外，外生性形态明显占主导。微观研究表明，所有病例均以表皮样癌为主，细胞分化程度中等。手术标本用火棉胶包埋，分别在水平和额状平面切片，然后用苏木精和伊红染色。
