“…The cytomorphologic features of infection with Trichomonas vaginalis, historically described as including inflammatory ''cannonball'' squamous cells with perinuclear halos, reactive nuclear changes, and attachment of Trichomonas organisms to squamous cells, are well recognized in LBP tests. 10,11 The high level of concordance to the reference diagnosis for all 3 preparation types in this study and for both reader types indicates that practitioners are familiar with these features and are able to apply them accurately. Papanicolaou tests with Trichomonas are infrequently misdiagnosed as epithelial abnormalities (2.4%; 4057 of 167 956) in the CAP-PAP program, pathologists almost twice as likely to make this error as cytotechnologists.…”

Performance is high in the detection of Trichomonas vaginalis in the College of American Pathologists Interlaboratory Comparison Program in Gynecologic Cytology. Liquid-based Papanicolaou and proficiency testing minimally affected participant performance. Cytotechnologists performed better over time and across preparation types than did pathologists, although pathologists showed performance results parallel to that of the cytotechnologists. Awareness of the performance differences by pathologists and cytotechnologists, as well as their difference in proficiency among liquid-based techniques, may help ensure accurate results in clinical practice.

Objectives: Cytolytic vaginosis is a very rare entity that may be clinically misdiagnosed as vulvovaginal candidiasis. The aim of this study was to determine the incidence of cytolytic vaginosis in patients displaying symptoms similar to vulvovaginal candidiasis and to develop a clinicopathological diagnostic and therapeutic approach. Materials and Methods: In total, 3000 cervical smear samples were evaluated at our center between 2015 and 2018. Patients whose PAP smears demonstrated significant epithelial cytolysis, naked nuclei, excessive increase in lactobacilli population, absent or minimal neutrophils and no microorganisms were subjected to a symptom assessment questionnaire and had their vaginal pHs measured. They were classified into two groups according to their complaints, symptoms and vaginal pHs: Cytolytic vaginosis and Asymptomatic intravaginal lactobacillus overgrowth. A standardized NaHCO3 Sitz bath therapy was applied to the cytolytic vaginosis group. Results: Fifty-three of the patients (1.7%) were diagnosed as cytolytic vaginosis. After Sitz bath therapy, there was a statistically significant decrease in the cytolysis and lactobacillus scores of the patients. Vaginal discharge of 43 (81%) patients ceased completely while that of the remaining 10 (19%) patients decreased after the therapy. The improvement was statistically significant ( P < 0.001). There was a complete resolution in 28 (96%) patients with severe; and in 21 (94%) patients with intermediate vaginal discomfort, after the therapy. Dyspareunia was resolved in 35 (97%) patients ( P < 0.001). Conclusion: Cytolytic vaginosis is a rare entity that can be diagnosed with the help of cytopathology and has a therapy based on the modulation microbiota by decreasing the vaginal pH.

“…La Trichomona vaginalis (Figura 1C) solo se registró en la citología en base líquida utilizando los criterios morfológicos asociados con esta infección. 33,34 En la actualidad la adquisición por parte de la Facultad de Citohistología del equipo manual para la técnica de base líquida de la casa comercial Becton Dickinson, nos permite enriquecer nuestra experiencia en el campo de la investigación, proponiendo nuevos temas tanto en citología vaginal como no ginecológica, y la aplicación de otras técnicas como la prueba de detección del HPV. 35,36 Haciendo una revisión acerca del tema se encuentra una publicación del Ministerio de Salud y Protección Social y del Instituto Nacional de Cancerología Empresa Social del Estado en su "PLAN NACIONAL PARA EL CONTROL DEL CÁNCER EN COLOM-BIA 2012-2020".…”

ResumenObjetivo: estandarizar la técnica de citología en base líquida mediante el uso del medio fijador (BDSUREPAth) y de citocentrífuga e identificar las posibles ventajas sobre citología convencional en muestra compartida de tomas cervicouterinas. Métodos: se incluyeron 92 muestras de mujeres que asistieron a las campañas del programa de proyección social de la Fundación Universitaria de Ciencias de la Salud, Bogotá DC, Colombia. Resultados: de las 92 muestras, 89 fueron negativas para citología convencional y 75 para base líquida, observándose un mayor número de casos con anormalidades en células escamosas en citología en base líquida. Conclusiones: las células escamosas mantienen su tonalidad citoplasmática siendo basófilas o acidófilas, conservando lo translúcido de los citoplasmas; las células glandulares preservan su patrón en panal de abejas o empalizada. Mediante citología en base liquida se obtienen fondos más limpios, las atipias de las células epiteliales fueron más fáciles de identificar al igual que los microorganismos patógenos. Palabras clave: citología, citología convencional, citología base líquida. Abreviaturas: VPH, virus del papiloma humano; ASC-US, células escamosas atípicas de significado indeterminado.Objective: to standardize the use of BD SurePath and centrifuged liquid-based cytology and identify possible advantages over the use of conventional cytology by comparing results on shared cervical samples analysis. Methods: we included 92 samples collected from women who attended the social projection campaign conducted by Fundación Universitaria de Ciencias de la Salud, Bogotá DC, Colombia. Results: out of the 92 samples, 89 were negative by conventional cytology and 75 by liquid-based cytology, evidencing a greater number of cases where squamous cell anomalies were detected using liquid-based cytology. Conclusions: squamous cells cytoplasma maintains its tone, being basophilic and acidophilic, conserving translucence; glandular cells preserve their honeycomb or palisade pattern. Liquid-based cytology gives a more clean background and improves identification of epithelial cell atypia as well as pathogenic microorganisms.
