上皮细胞瘤

Cancer of ovarian and transparent cell is most constant tumour of as epithelial as the ovarian surface of confuse of interblend of tumour of cell of the former reproduction that send a gender sex, especially with yolk bursa tumour and asexuality cell tumour are differentiated harder.

梗概： 卵巢透明细胞癌是最常和原发性生殖细胞肿瘤相混淆的卵巢表面上皮性肿瘤，尤其和卵黄囊瘤和无性细胞瘤较难鉴别。

Epithelium type tumour cell's Epithelium structure having various diversity the mammilla shape tubulous be in charge of the mammilla shape tape meritorious service slice a shape for instance.

恶性璋皮瘤的病理组织学分型有上皮型、纤维型和混合型三种。上皮型肿瘤细胞的上皮有各种不同的结构，例如乳头状、管状、管乳头状、带状功片状。

A core needle biopsy misdiagnosed PASH in 13 cases out of 28 cases and vacuum-assisted biopsy correctly identified PASH in all 3 cases.

4细胞性纤维腺瘤和囊肉瘤：PASH缺乏真正的间叶细胞过生长的现象，其细胞缺乏多形性，无核分裂象，也没有纤维腺瘤或囊肉瘤的上皮成分的生长类型。

In other areas, sheets of epithelioid cells with prominent nuclear pleomorphism were seen; scattered tumor giant cells and multinucleated tumor cells were also present (Figure 1, B ).

在其他区域，可以见到成片的具有明显多型现象的上皮样细胞；散在的瘤巨细胞和多核瘤细胞也可以见到(图1B)。

Result of HE and special dye1.1 result of HE More cells are found in subsequent cholesteatoma. Cholesterol crystal, both sequestrum and neogenesis bone , gland metaplasia, Polykaryocyte are found in subepidermis of subsequent cholesteatoma.

结果1、HE染色结果：可见后天性胆脂瘤上皮的细胞层次增多，上皮内及上皮下有不同程度的急性、慢性炎细胞浸涧；上皮下有时可见胆固醇肉芽肿、死骨与新骨形成、腺体化生等病理改变。

Results With the expression in normal salivary gland as a standard, low C-erbB-2 mRNA expression was seen in adenolymphoma, basal cell adenoma. However, various degrees of over-expression of C-erbB-2 oncogene mRNA were detected in pleomorphic adenoma, mucoepidermoid carcinoma,acinic cell carcinoma ,adenoid cystic carcinoma ,papillary cystic carcinoma,and myoethelial cell carcinoma.

结果 正常涎腺和涎腺肿瘤中发现不同程度C-erbB-2mRNA的表达，以正常涎腺组织的表达水平为基准，在腺淋巴瘤、基底细胞腺瘤呈现低表达、无表达或与正常涎腺组织表达水平相似，多形性腺瘤、粘液表皮样癌、腺泡细胞癌、腺样囊性癌、乳头状囊腺癌和肌上皮癌则呈现不同程度的过表达。

We conclude that (1) S100A1 is a specific and sensitive immunohistochemical marker to differentiate nephrogenic adenoma from prostatic adenocarcinoma;(2) AMACR immunostaining does not seem to be a useful marker in distinguishing between these 2 lesions;(3) given that both S100A1 and AMACR have been reported to be expressed in renal tubular cells and in a subset of renal cell neoplasms, our findings confirm the histogenetic relationship between nephrogenic adenoma and renal tubular epithelium.

我们总结认为：（1）鉴别肾源性腺瘤和前列腺腺癌，S100A1既特异又敏感；（2）AMACR免疫染色鉴别这两种病变，效用不佳；（3）文献报道S100A1和AMACR均表达于肾小管上皮和部分肾细胞肿瘤，在此前提下，我们的结果证实了肾源性腺瘤和肾小管上皮之间的组织发生关系。

HPV infection can arouse the cleavage and proliferation of cholesteatoma epithelium and may play certain role in the occurrence and development of middle ear cholesteatoma. Aggressive, papillomatous growth and koilocytes can be served as the initial proof of HPV infection in cholesteatoma of the middle ear.

HPV感染可能激发中耳胆脂瘤上皮的分裂增殖，在中耳胆脂瘤发生发展中起一定的作用；侵蚀性乳头瘤样生长和空晕细胞改变可以作为中耳胆脂瘤组织中HPV感染的病理学证据。

There were all kinds of tissue cells in the teratomas acquired from in-vitro differentiation, such as, neuro epithelium, skeletal muscle, respiratory epithelium. This further proved the isolated mouse ES cells could differentiate into three germ layers of tissue types.

体内分化实验所获得的畸胎瘤中存在各种组织细胞，如一些神经上皮样组织；横纹肌；呼吸上皮样组织等，这进一步证明所分离获得的小鼠ES细胞具有三个胚层的分化能力。
