摘要：

目的 探讨人乳头瘤病毒（HPV）与皮肤Bowen病发病的相关性。方法 41例皮肤Bowen病患者皮损以及48例健康对照皮肤，采用多对引物，应用巢式PCR进行HPV DNA检测，同时应用半定量PCR进行病毒定量，对HPV DNA阳性标本进一步采用原位杂交方法分析组织内病毒的分布状况。结果 41例皮肤Bowen病患者皮损HPV DNA阳性检出率为12%（5例），其中黏膜型3例（2例HPV16，1例HPV33），病毒定量相当于101 ~ 103拷贝，原位杂交显示在多数肿瘤细胞核中有广泛阳性表达，而肿瘤邻近的正常组织无信号表达；皮肤型2例（HPV27和HPV76各1例），原位杂交均无阳性表达。此外，对照组中有1例检出HPV DNA，属于疣状表皮发育不良相关型HPV23，检出率为2.1%，与皮肤Bowen病皮损中HPV检出率比较，差异无统计学意义。2例患者皮肤型病毒定量较低，与正常对照组中检出的1例HPV23相似，均相当于10-2 ~ 10-3拷贝。结论 某些皮肤Bowen病的发病与黏膜型HPV密切相关。

Abstract:

Objective To assess the relationship between human papillomavirus （HPV） and extragenital Bowen′s disease. Methods Regular PCR with consensus primers for L1 region as well as mix primers and nested PCR were performed to detect the DNA of a broad range of cutaneous and mucosal HPV types in tissue samples from lesions of 41 patients with extragenital Bowen′s disease and from normal skin of 48 human controls. Semiquantitative PCR and tyramide-based in situ hybridization （ISH） were also conducted to determine the load and localization of HPV DNA in HPV-positive samples. Results HPV DNA was detected in lesions from 5 （12%） of the 41 patients with extragenital Bowen′s disease. Of the 5 HPV-positive patients, 3 carried mucosal HPV types （HPV16 in 2 cases, HPV 33 in 1 case） with a viral load of 101 to 103 copies, 2 cutaneous HPV types （HPV27 in 1 case and HPV76 in 1 case）. As ISH showed, there was a generalized expression of mucosal HPV DNA in most tumor cell nuclei but not in peritumoral normal tissue, and no expression of cutaneous HPV DNA was observed in lesions. HPV DNA was detected in 1 （2.1%） control tissue sample, which proved to be epidermodysplasia verruciformis-associated HPV23. There was no significant difference in the detection rate of HPV DNA between the patients and controls. The viral load of cutaneous HPV types amounted to 10-2 to 10-3 copies in the 2 patients, which was similar to that of HPV 23 in the normal control. Conclusion Mucosal HPV types may be closely associated with the development of extragenital Bowen′s disease.
