摘要:

目的 探讨角化棘皮瘤组织中人乳头瘤病毒(HPV)感染率,及HPV DNA阳性细胞的分布特征。方法 原位杂交方法检测46例KA和34例正常人皮肤石蜡切片组织标本中HPV6/11、16/18、31/33亚型。结果 31例角化棘皮瘤黏膜型HPV DNA阳性,总阳性率67.39%,两种以上HPV混合感染达83.87%(26/31),各亚型均以游离型为主;阳性信号位于细胞核内或核边缘,阳性细胞多分布于火山口底部棘层的浅中部及其周围唇部,分布形式多为带状、片状或灶状聚集。正常皮肤对照组HPV DNA各亚型检测均阴性。结论 角化棘皮瘤患者HPV6/11、16/18、31/33感染率高于正常人群,且以游离形式存在为主,推测HPV感染在角化棘皮瘤的发病机制中起作用。

Abstract:

Objective To detect the infection rate of human papillomavirus (HPV) types in keratoacanthoma (KA) tissue, and to study the distribution of HPV DNA-positive cells. Methods In situ hybridization was performed to detect HPV subtypes 6/11, 16/18, and 31/33 in paraffin-embeded tissue samples from 46 patients with KA and 34 nomal human controls. Results Mucosal HPV DNA was positive in 31 (67.39%) of the 46 KA samples, and mixed infection rate of HPV amounted to 83.87% (26/31) in these positive samples. The DNA of tested mucosal HPV types existed mainly in episomal status. Positive reactions were observed within or at the edge of nuclei. HPV infected cells showed a stripe-, slice-like or focal distribution mainly in superficial middle lamina of spinous layer at the bottom or lateral margin of crater-shaped epidermal depression. No mucosal HPV DNA was noted in normal control samples. Conclusions Compared with normal controls, patients with KA are infected with mucosal HPV at a higher frequency, and mucosal HPV DNA mainly exists in episomal status in KA tissue, hinting that HPV infection play a certain role in the pathogenesis of KA.
