基底细胞腺瘤由单一成份组成,有四种亚型:(1)实性,(2)小梁状,(3)管状,(4)膜状。小管状腺瘤为另一种单一成份组成的腺瘤,不能与基底细胞腺瘤,特别是小梁型相混淆。作者分析了112例唾液腺,其中73例为小管状腺瘤,39例为基底细胞腺瘤。对77个肿瘤切片作HE染色,其中13个肿瘤既作PAS染色,又作了奥新兰(pH2.5)、粘卡红、Gomori′s醛复红、Perl′s普鲁士兰或甲苯胺兰染色。对2例基底细胞腺瘤、3例小管状腺瘤作了电镜制片观察。小管状腺瘤主要由呈双层排列的柱状细胞组成,其间有数量不等的类基底细胞散在分布。基底细胞腺瘤除导管样结构外,主要 Basal cell adenomas consist of a single component and there are four subtypes: (1) solid, (2) trabecular, (3) tubular, and (4) membranous. Small tubular adenomas are another single-component adenoma that cannot be confused with basal cell adenomas, particularly trabecular ones. The authors analyzed 112 cases of salivary glands, of which 73 were small tubular adenomas and 39 were basal cell adenomas. Seventy-seven tumor sections were HE-stained. Thirteen tumors were stained with either PAS or ointment (pH 2.5), stuck-red, Gomori’s aldehyde red, Perl’s Prussian blue, or toluidine blue. dyeing. Two cases of basal cell adenomas and three cases of small tubular adenomas were observed by electron microscopy. Small tubular adenomas are mainly composed of columnar cells arranged in a bilayer with a heterogeneous distribution of basal cells. Basal cell adenomas, except for duct-like structures, are mainly
