【摘要】 将聚合酶链式反应(PCR)技术与光镜、电镜下的形态学观察相结合,对63例女性生殖道疣样病损活检标本进行综合研究。PCR检测结果:在26例新鲜组织中,人乳头状瘤病毒(HPV)6/11b型阳性者21例(80.8%);在12例石蜡包埋组织中,HPV6/11b阳性者7例(58.3%),总阳性率为73.7%。光镜观察:21例HPV阳性病例中,19例显示典型的尖锐湿疣病变,另2例未发现典型的挖空细胞,基底细胞增生也不明显;HPV阴性病例绝大部分无典型尖锐湿疣表现,但有1例在中、表层也出现了成堆的挖空细胞。电镜观察发现:HPV阳性病例的超微结构显示一定程度的规律性。提示:尖锐湿疣系HPV感染所引起,将光镜、电镜的形态学观察与PCR技术检测HPV相结合,对之进行综合诊断,可减少尖锐湿疣的误诊与漏诊;HPV阳性的湿疣组织中,病毒颗粒的出现机率极小,研究中发现的与病毒感染有关的超微病变,可试作电镜下诊断尖锐湿疣的依据

【Abstract】 HPVDNA and corresponding ultrastructural changes were studied with polymerase chain reaction(PCR) and electron microscopy (EM) in 63 female genital condylomatoid biopsy specimens.The PCR examinational results revealed that Type 6/11b HPVDNA was detected in 21 of the 26 fresh specimens (80.8%) and in 7 of 12 paraffinembedded tissue specimens (58.3%),the total HPVDNA positivity rate being 73.7%.Under light microscope,19 of 21 HPVDNA positive cases showed typical pathological changes of condyloma acuminatum (CA),while in the other 2 cases no such changes could be found.No typical CA appearance was found in the HPVDNA negative cases except one case which showed a large number of koilocytes in the stratum spinosum that near the surface.Ultrastructure of HPVDNA positive cases under EM displayed some characteristic changes,which were likely related to virus infection.It could be of great value in decreasing misdiagnosis of CA to combine PCR examination with light and electron microscopic observation in the diagnosis of genital condyloma latum.Virus particles were seldom found in the CA specimens.The characteristic changes of HPV positive CA might be used in the diagnosis of CA under EM.
