Background: Recent data have shown that the human papillomavirus (HPV) vaccine could impact on a decrease in high-grade cervical intraepithelial lesions (HSIL) in women who have undergone surgical treatment. This study aimed to evaluate the efficacy of human papilloma virus (HPV) vaccination against persistent/recurrent disease in patients undergoing conization for high-grade squamous intraepithelial lesion/cervical intraepithelial neoplasia-grade 2-3 (HSIL/CIN 2-3). Methods: From January 2009 to March 2019, 563 patients with HSIL/CIN 2-3 underwent conization. The population was divided into two groups according to vaccination status: vaccinated-group (V-Group) and non-vaccinated-group (NV-Group). Bivalent or quadrivalent vaccines were administered indiscriminately. A follow-up was scheduled every 6–12 months according to clinical guidelines. The mean follow-up was 29.6 vs. 36.5 months in the V-group and NV-group, respectively. Results: 277 (49.2%) women were vaccinated, while 286 (50.8%) were not. Overall, persistent/recurrent HSIL/CIN 2-3 was presented by 12/277 (4.3%) women in the V-Group and 28/286 (9.8%) in the NV-Group (HR: 0.43, 95% Confidence interval 0.22–0.84, p = 0.014). Vaccination was associated with a 57% reduction in HSIL persistence/recurrence after treatment. When no disease was present in the first 6-month follow-up visit, persistence/recurrence rates were very low in both groups: 1.1% in the V-Group vs. 1.5% in the NV-Group (p > 0.05). The factor associated with a high-risk of HSIL persistence/recurrence was the presentation of a positive co-test in the first control after treatment (p < 0.001). Conclusions: Our results corroborate the benefit of HPV vaccination in woman treated for HSIL/CIN 2-3, showing a reduction of persistent/recurrent HSIL/CIN 2-3.

RESUMENLa úlcera de Lipschütz es una entidad poco frecuente e infradiagnosticada. Se presenta el caso de una paciente de 24 años sin antecedente de contacto sexual que consultó por aparición súbita de úlceras vulvares dolorosas, en el contexto de un cuadro pseudogripal. Se discuten los principales diagnósticos diferenciales, dado que es una enfermedad no relacionada con enfermedades de transmisión sexual y poco reconocida por los profesionales de la salud, que precisa de manejo conservador.Palabras clave: Úlcera genital aguda, úlcera de Lipschütz, enfermedad vulvar. ABSTRACTLipschütz ulcer is a rare underdiagnosed entity. We present the case of a 24-year-old patient without history of sexual contact who consulted for sudden occurrence of painful vulvar ulcers, in the context of flu-like symptoms. The main differential diagnoses are discussed, as it is a disease unrelated to sexually transmitted diseases and little recognized by health professionals, which requires conservative management.
