Objective: To observe the effectiveness of chlortetracycline (aureomycin) treatment on vulval white lesions and to explore its possible pathogenesis. Materials and Methods: From January 2001 to April 2011, 194 patients with vulvar non-neoplastic epithelial disorders were divided into three groups according to therapy regimens received, ie, chlortetracycline treatment group (72 cases), chlortetracycline + beclomethasone treatment group (66 cases), and beclomethasone treatment group (56 cases); their local changes of vulvar lesions were observed and efficacy of these treatment profiles was evaluated after one year. Results: Effective rates of chlortetracycline group, chlortetracycline + clobetasol group and clobetasol groups were 86.1% (62/72), 87.9% (58/66), and 62.5% (35/56), respectively. There was a significant difference among these three groups (Hc = 10.7766, p = 0.0046), the curative rate of clobetasol group was markedly lower than that of the former two groups (p = 0.0072 and p = 0.0019), but was not statistical significant (p = 0.6077) when compared between the former groups. Conclusion: The occurrence of vulvar non-neoplastic epithelial disorders may be associated with chlamydia and mycoplasma infection, the chlortetracycline is an effective drug for this illness, the mechanism of which might be related to killing pathogens directly and inhibiting inflammatory mediators.
