A case of squamous-cell carcinoma arising in association with perianal condyloma acuminatum was studied by light microscopy. The eight previously reported cases of malignant transformation of perianal and anorectal condylomata acuminatum are reviewed and the salient features described. Light microscopic examination of the case reported here demonstrated several foci of subtle and abrupt transition from condyloma acuminatum to epithelial dysplasia and to carcinomain situ with focal frank invasion. This study further substantiates the existence of malignant transformation of condyloma acuminatum, particularly in perianal skin.  相似文献

Objective This study was performed to identify the presence of previously reported thyroglobulin (Tg) gene single nucleotide polymorphisms (SNPs) in Han Chinese Asians, and to investigate their potential relation to autoimmune thyroid disease (AITD). Methods Polymorphisms were determined by polymerase chain reaction-restriction fragment length polymorphism analysis (PCR-RFLP) in 228 Chinese patients with AITD (146 with Graves’ disease and 82 with Hashimoto’s thyroiditis) and 131 healthy Chinese controls. Results (1) The occurrence of four common Tg gene SNPs (E10SNP24 T/G and E10SNP158 T/C in exon 10, E12SNP A/G in exon 12, and E33SNP C/T in exon 33) was confirmed in this Chinese population. No differences in allele and genotype frequencies were found between AITD patients and control subjects, or between male and female individuals in any group. Neither were differences in allele frequencies observed when Graves’ disease (GD) or Hashimoto’s thyroiditis (HT) patients were analyzed separately. (2) Haplotype analysis of these four SNPs revealed that the G-C-A-C haplotype was significantly associated with HT (P < 0.01, OR = 3.06, OR 95% CI [1.326–7.089]) and with serum anti-Tg antibody (Tg-Ab) positive AITD patients (P = 0.028, OR = 3.34). Conclusion Our study confirms the existence of four SNPs among Han Chinese. In addition, the association of one SNP haplotype with HT suggests that Tg may be an AITD susceptibility gene.  相似文献

AIM: To investigate the correlation between C/T single nucleotide polymorphism (SNP) in the promoter of the DNA methyltransferase 3B (D/VMT3B) gene and risk for development and progression of primary hepatocellular carcinoma (HCC). METHODS: One hundred case subjects were selected consecutively from Tongji Hospital (Wuhan, China). from March to November 2006. They did not receive radiotherapy or chemotherapy for newly diagnosed and histopathologically confirmed HCC. One hundred and forty control subjects having no history of cancerous or genetic diseases were healthy volunteers to Wuhan Blood Center in the same period. Frequency was matched for sex, age, alcohol consumption and cigarette smoking status of the case subjects. C/T polymorphism of the DNMT3B promoter was analyzed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequencing analysis. The association between genotypes of DNMT3B and clinicopathological parameters among cases was also studied. RESULTS: The CC genotype HCC patients and controls. was not detected in both In control subjects, the frequency of TT and CT genotypes was 99.3% and 0.7% respectively, and that of T and C alleles was 99.6% and 0.4% respectively. The frequency of CT genotype was higher in HCC (3.0%). The frequency of T and C alleles was 98.5% and 1.5% respectively. However, the genotype and allelotype distribution in HCC patients was not significantly different from that in controls. CONCLUSION: C/T polymorphism is not associated with the increased risk of HCC. DNMT3B genetic polymorphism is variable in different races, ethnic groups or geographic areas. Further study is needed to clarify the role of DNMT3B SNP in the development of HCCamong other populations.  相似文献

Methods A case-control study was adopted. The genotype, allele and haplotype frequency of three polymorphic sites (-1654C/T,-1641A/G and -1476A/T) were determined and analyzed by direct sequencing in 110 patients with PTE and 100 healthy controls. The plasma PC level was detected by enzyme linked immunosorbent assay. group (P < 0.01 or P < 0.05). There was no statistical significance on the family history of thromboembolism and cardiovascular diseases, trauma history, history of oral contraceptives, smoking distribution of PC gene - 1654C/T site between the two groups. T allele frequency was higher in case group, C allele frequency was higher in control group. There was no statistical significance on genotype Haplotype analysis showed that three polymorphism sites of PC gene composed three kinds of haplotype ( - 1654T/- 164 1A/- 1476A, - 1654C/- 164 1A/- 1476A and - 1654C/- 1641G/- 1476T ). There was statistical significance on frequency distribution of TAA and CAA haplotypes between the two groups CAA was lower than that in subjects carried CAA and non-carried TAA, but there was no statistical significance between the two groups. Conclusions PC gene regulatory region polymorphism may be associated with the susceptibility to PTE in Shanghai Han population, but it is further confirmed that the association of PC gene polymorphism with plasma PC level.  相似文献
