We studied the electron microscopic and immu-
nohistochemical findings in two elderly patients with
spindle cell carcinoma of thecornea and conjunctiva.By light microscopy, correctdiagnosis was made by
finding the transition between the pleomorphic spindle
shaped tumor cells and the ovcrlying squamous
epithelium. Ultrastructural findings indicated that
squamous ceIJ origin included tonofilament-associated
desmosomes and keratohyaline granules in the tumor
cells. Positive immunohistochemical staining with
antikeratin antibodies provided further evidence to
prove the origin of spindle ceIJ carcinoma. Follow-up
of the two patients showed the malignant tumor to bc
quite aggressive in terms of intraocular invasion in the
first patient and local recurrence in the second. 相似文献

24只新西兰兔,随机分为4组。右膝髌骨手术方法造成髌骨倾斜状态为实验侧,左膝实施假手术为对照侧,定期处死动物后进行软骨组织病理观察以及纤维连接蛋白的免疫组化(LAB法)定位。结果:术后12周实验膝髌内侧面软骨中层、深层细胞与细胞外基质变性并形成裂隙,与髌软骨软化的病理改变相似。上述软骨变性部位软骨细胞浆内以及细胞外软骨基质纤维连接蛋白明显增多,特别是软骨细胞周缘与基质交界处增多最显著。表明纤维连接蛋白增多部位与髌软骨软化部位一致,纤维连接蛋白增多与髌软骨软化的发生密切相关。 相似文献
