scar carcinoma

An approach to pathological diagnosis of burn scar carcinoma of skin

皮肤烧伤瘢痕癌的病理诊断探讨

The displacement phenomenon of K-ras proteins may be related to the occurrence of skin scar carcinoma .

K-ras蛋白的移位现象，可能与瘢痕癌的发生有相关性。

Burning scar carcinoma ( a report of 11 cases )

Correlation between Cx43 and survivin expression in skin scar carcinoma

皮肤瘢痕癌变组织中Cx43、Survivin表达的相关性

The results show that the immunohistochemical methods of PCNA and s-100 protein staining are useful in differentiation between burn scar carcinoma and pseudoepitheliomatous hyperplasia .

因此PCNA及S－100免疫组化染色有助于皮肤烧伤瘢痕癌与皮肤烧伤假上皮瘤样增生的鉴别。

H-ras , N-ras and K-ras proteins were related to the differentiation of tumor cell , these proteins may gradually lose in the evolution of skin scar carcinoma .

H-ras、N-ras、K-ras蛋白与肿瘤细胞的分化有相关性，可能在瘢痕癌演进过程中逐渐丢失。

The codons 12 and 13 of Ras family were not examined to have the mutation in skin scar carcinoma , the mutation situs of Ras family is to be further explored .

瘢痕癌中尚未发现Ras基因家族12、13位密码子的突变，其突变位点有待进一步探讨。

Proliferating cell nuclear antigen ( PCNA ) and s-100 protein in 5 cases of burn scar carcinoma demonstrated by immunohistochemical staining procedures were compared with those in pseudo-epitheliomatous hyperplasia arising from burn scars .

本文对5例皮肤烧伤瘢痕癌进行了PCNA及S－100免疫组化染色观察，并与皮肤烧伤假上皮瘤样增生进行了对比。

The Expressions of Cx43 Protein and Cx43 mRNA in Skin Scar and Scar Carcinoma

Cx43蛋白和Cx43mRNA在皮肤瘢痕及瘢痕癌组织中的表达

Methods : We used pathological skin scar tissues and skin scar carcinoma tissues to compare with normal skin tissues .

方法：以病理性皮肤瘢痕、皮肤瘢痕癌组织为研究对象，以正常皮肤组织为对照。

Compared with normal skin and skin pathological scar , the high expression of H-ras , N-ras and K-ras proteins may be related to the occurrence of skin scar carcinoma .

瘢痕癌与正常皮肤和皮肤病理性瘢痕相比较，H-ras、N-ras、K-ras蛋白的高表达，可能与皮肤瘢痕癌的发生有关。

But the differences of expression was no statistically significant between normal skin group and pathological skin scar group . ( 3 ) CyclinD1and its mRNA showed negative expression in normal skin epidermis , weakly positive expression in pathological scar epithelium , strongly positive expression in scar carcinoma group .

CyclinD1蛋白、CyclinD1mRNA在正常皮肤表皮呈阴性表达，在病理性瘢痕上皮中呈弱阳性表达，在瘢痕癌组织中呈强阳性表达。
